A term related to but different from Coronal mass ejections.

See CDS Object Type list. http://simbad.u-strasbg.fr/simbad/sim-display?data=otypes

  ·  ·  Candidate_S*     	S*?     	Possible S Star    
  ·  ·  Candidate_OH     	OH?     	Possible Star with envelope of OH/IR type    
  ·  ·  Candidate_CH     	CH?     	Possible Star with envelope of CH type    
  ·  ·  Candidate_WR*     	WR?     	Possible Wolf-Rayet Star    
  ·  ·  Candidate_Be*     	Be?     	Possible Be Star   

For example, CDS classifiers find it useful to be able to classify an object as "Possible S Star" when the referenced authors believe the object might be an S Star but aren't certain.

Is there a way to add "Possible" as a modifier instead of adding a large set of concepts?

Added a category for subdwarfs. Many people study them as a group.

Stellar types-->Subdwarfs-->A subdwarfs
Stellar types-->Subdwarfs-->B subdwarfs
Stellar types-->Subdwarfs-->O subdwarfs
Stellar types-->Subdwarfs-->F subdwarfs
Stellar types-->Subdwarfs-->K subdwarfs
Stellar types-->Subdwarfs-->M subdwarfs
Stellar types-->Subdwarfs

Moved "Irregular variable stars" out from "Late-type giants". Not all Irregular variables are giants, e.g. T tauri and soft gamma ray repeaters.

I suggest relabelling 'Mercury' as 'Mercury (planet)', as with 'Earth (planet)'. This will help disambiguate usage for the chemical element.

Added "Blue compact dwarf galaxies" and group it with "Ultracompact dwarf galaxies" in a new "Compact dwarf galaxy category." - These were terms in the APT vocab.

Cosmology->Astronomical radiation sources
-> Gamma-ray sources
-> Visible sources

Currently Siderostats is both a child and sibling of "stellar tracking devices." This should only be a child of "Stellar tracking devices," so the concept needs to be unlinked from "Instrumentation."

Moved "Emission line stars" out from "Variable stars" because not all emission line stars are variable.

Stellar astronomy->Stellar physics->Star formation->Star forming region

Added "Shell star" category. In the APT vocab. Defined here as "A hot main-sequence star, usually of spectral class B, A, or F, whose spectrum shows bright emission lines presumed to be due to a gaseous ring or shell surrounding the star."

Stellar astronomy-->Stellar types-->Chemically peculiar stars-->Shell stars

Rename "Methods" to something like "Observational regimes." Check into the literature to see how "regime" is used in context.

Moved RR Lyrae variables from under Population II Cepheid stars. RR Lyrae are different from Cepheid stars.

Move the following concepts OUT of "astronomical research" and into some other grouping concept relating to people in astronomy, uncertain what this should be.

Amateur astronomers
Astronomers
Astrophysicists
Sociology of astronomy

Looks to be a frequently used term for a particular kind of luminosity. Also used similarly: "Blackbody brightness"

Galactic and extragalactic astronomy->Galaxy clusters
->Rich clusters
->Poor clusters
->High-redshift clusters

Add concept "Solar dynamo" as child of "Solar cycle."

Best practices in controlled vocabularies for plural vs. singular nouns (section 6.5 of Z39.19 http://www.niso.org/apps/group_public/download.php/12591/z39-19-2005r2010.pdf):

Count Nouns are subject to the question "How many?" i.e. "How many books?" "How many galaxies?"
Mass Nouns are subject to the question "How much?" i.e. "How much copper paint?" "How much interstellar dust?"

Exceptions:
Noun as a class with more than one member, i.e. "paints" to describe many different types of paint.
Domain use, i.e. "ear" in a medical vocabulary, since they are generally considered as singular in the domain.
Abstract concepts, such as activities, emotions, properties, should be expressed as singular.
Proper names should be singular, such as "Milky Way Galaxy" or "Solar System."

Make Plural:
Dust shell
Rotating shell
Convective zone
Convective envelope
Stellar interior
Stellar structure
Carbon flash
Circumstellar envelope
Stellar inner core

Make Singular?
Stellar masses (falls under the exception of "properties"?)
Stellar mass functions (check other functions)
(consider all concepts under "Stellar properties")

Appears to be a particular kind of radiation. Also seen phrased "blackbody isotropic radiation" but less frequently

Added "Exoplanet System" - This is a term that was in our Astronomer's Proposal Tool (APT) target descriptor vocabulary and is a natural complement to the existing terms in this category (Exoplanets, Planet hosting stars)

Make "Observatories" sibling of "Instrumentation."

I also have a large-ish list of pairs of concepts that are both siblings and ancestors, e.g.:
Galactic and extragalactic astronomy,Galaxy physics,Galaxy dynamics,,,,,,,
Galactic and extragalactic astronomy,Galaxy physics,Galaxy processes,Galaxy dynamics,,,,,,
I will attach the list but maybe we should start a Google doc somewhere and we can make it a group effort to fix these as we have time? Some of them are obvious how to fix, but not all. Just a thought. I'll let you decide!

First I would set "Planetary Atmosphere" and "Planetary Magnetosphere", as two different terms next to the other. I'm sure I've ever seen the magnetosphere defined as a layer of the atmosphere of a planet. Furthermore, all planetary body hosting a magnetic field has a magnetosphere, not only Earth. At the moment, in the UAT, only "Earth Atmosphere" has a "magnetosphere" child concept.

I would see something like this:
Solar System Astronomy : Planetary science : Planetary Magnetosphere : Magnetospheric radio emissions
Solar System Astronomy : Planetary science : Planetary Magnetosphere : Earth Magnetosphere : Magnetospheric radio emission

If you want to see at "working case", used for data description, have a look to the SPASE Region concept:
http://spase-group.org/data/reference/spase-2_2_6/spase-2_2_6_xsd.htm#Region

Added category of "Y dwarfs" under "Brown dwarfs"

Move "Analytical mathematics" from "Astronomical research" to "Techniques."

Stellar astronomy->Stellar types->Evolved stars->Subgiant stars->O subgiants

Added category for transients - X-ray source means something that is always there. A transient wouldn't be seen except for a brief period of time where it goes off and then you don't see it anymore. These were in APT but not in UAT.

High energy astrophysics -->Transients -->Gamma Ray bursters
High energy astrophysics -->Transients -->Gamma Ray transients
High energy astrophysics -->Transients -->UV transients
High energy astrophysics -->Transients -->X-ray transients
High energy astrophysics -->Transients

Also, there are a couple of concepts that might have duplicates:
semiregular variables vs. semi-regular variables
circumstellar shell vs. circumstellar shells

Cleaned up binary star sections. There were some things that weren't under the Interacting binaries section that should be. Eruptive binaries is an uncommon term, so removed it. "Close binaries" and "Interacting binaries" are almost the same thing, but technically not. I was tempted to merge these into one category, but was advised to keep them separate by our scientists.

See attached for more detail.

Merge "Helioseismology" into "Solar interior."

Reorganized Main sequence category - Main sequence stars are synonymous with dwarf stars, so anything that's not a dwarf should (not?) be in this category.

Main sequence stars-->Early-type main sequence stars-->A dwarfs
Main sequence stars-->Early-type main sequence stars-->B dwarfs
Main sequence stars-->Early-type main sequence stars-->O dwarfs
Main sequence stars-->Early-type main sequence stars
Main sequence stars-->Intermediate-type main sequence stars-->F dwarfs
Main sequence stars-->Intermediate-type main sequence stars-->F dwarfs-->Fp stars
Main sequence stars-->Intermediate-type main sequence stars-->G dwarfs
Main sequence stars-->Intermediate-type main sequence stars
Main sequence stars-->Late-type main sequence stars-->K dwarfs
Main sequence stars-->Late-type main sequence stars-->L dwarfs
Main sequence stars-->Late-type main sequence stars-->M dwarfs
Main sequence stars-->Late-type main sequence stars-->T dwarfs
Main sequence stars-->Late-type main sequence stars
Main sequence stars-->Yellow stragglers
Main sequence stars-->Zero-age main sequence stars
Main sequence stars

Cleaned up the "Irregular galaxies" category. The morphological classification of irregular galaxies typically contains three types Type 1 / magellanic irregular, type 2 / amorphous irregular and Dwarf Irregular. "I galaxies" isn't meaningful according to our scientists. We could add "Irr I galaxies" as a synonym for magellanic irregular and "Irr II galaxies" as a syonym for amorphus. (It's possible that "I galaxies" was supposed to mean "Irr I galaxies" but it's not clear to me.)

Add these concepts as children of "Solar interior":

Solar convection
Solar meridional circulation
Solar differential rotation

I am still working with the developers of the Astronomer's Proposal Tool (APT) at STScI, who are planning on using the UAT to replace their existing target vocabulary. I am pretty sure that many of the terms they currently use for describing calibration "targets" are not in the thesaurus. I was thinking that they could go under

Observational Astronomy -> Techniques -> Calibration

Add "Sunspot number" as child concept of "Sunspot cycle."

Move "astronomical site protection" to be under "observatories."

Added "Low surface brightness galaxies" - According to the NED glossary an L galaxy is "In Morgan's classification, an elongated galaxy of low surface brightness" so we moved this underneath the new category.

Galactic and extragalactic astronomy-->Galaxies-->Low surface brightness galaxies-->L galaxies

Add "P-modes" and "G-modes" under "Helioseismic pulsations."

Suggest revising the terms under 'Stellar abundances'. At present, they are

• Beryllium
• Boron
• Helium
• Lithium

These are chemical elements, not types of abundance, and therefore don't meet any of the three BT/NT relationships:

• All-and-some
• Whole/part
• Class/instance

I suggest revising the terms to:

• Beryllium abundance
• Boron abundance
• Helium abundance
• Lithium abundance
  i.e. making four new terms, with the relevant chemical elements linked as reltaed terms.

...the term "Magnetospheric radio emissions [Exoplanets]" [..] is presented as a narrower term than "Gravitational microlensing [Exoplanets]". I can't really understand on what ground that link was made. My suggestion would be that there is a "Magnetospheric radio emissions" (outside the exoplanet context), as those radio emissions are observed and studied since the 50's... while exoplanetary radio emissions have not been detected yet.

To me they [magnetospheric radio emissions and gravitational microlensing] are both possible detection methods for exoplanets, but there is no apparent hierarchical link between them.

More properly "Solar system planets," with no concept in the UAT being simply "planets."

Add related concept "Exoplanet" ?

And I just noticed that we used "O giant stars" instead of "O giants" like the rest of the "? giants" labels. These should probably be consistent.
