    Default Which catalog is best?



    I am looking for a good catalog of stars.

    Nothing fancy - bare minimum would be:

    Star Name
    Spectral Class
    R.A.
    Dec
    Distance from Sol


    That's it.

    A text file, comma separated value file, database or spreadsheet would be
    great.
    The simplier the better.

    If it could go out to 200 to 300 light years, it would be great.

    I'd buy a CD, pay-pal or Visa or whatever.

    Stars, binaries, dwarfs, etc....

    Any help or suggestions would be appreciated.

    Most astronomical data is available online for free, starting at
    http://cdsweb.u-strasbg.fr.

    I'm not sure what you want to do with your data, but I warn you that
    you are likely to be biting off more than you can chew; star catalogs
    can be pretty overwhelming.

    I recommend starting with the Yale Bright Star Catalog; it is simple,
    high-quality, complete, and not terribly huge -- just 9000 stars,
    basically all the ones that are visible to the naked eye. After you've
    played with that, you will have a better idea where you want to go next.

    No catalog is complete to 200 light-years from Earth; in fact, the
    overwhelming majority of stars within 200 l-y haven't even been detected
    yet, much less cataloged. We are still discovering new stars just 20 l-y
    from Earth!

    Another way to start would be with the Tycho catalog.

    The ESO has just announced a paper:

    "The Geneva-Copenhagen survey of the Solar neighbourhood: Ages,
    metallicities and kinematic properties of ~14,000 F and G dwarfs"

    by B. Nordström et al. The full article is available in PDF format here.

    http://www.edpsciences.org/papers/aa...ses/aa0959.pdf

    In the paper the give the address of the electronic form of the catalog
    of the 14k stars. IIRC this goes to about 140 ly, within this distance
    I estimate there are about 3x that many stars. This is a guess based
    on the Initial Mass Function ( more K & M stars, fewer OBAs ), but
    it is only a guess. Based on this a complete catalog to 300 ly would
    have about 330k entries.

    Dark skies,

    An attempt to exhaustively survey _all_ stars down through M-type subdwarves
    within a mere 10 parsecs (~32.6 ly) of Sol is curently being carried out
    by the RECONS group: <http://www.chara.gsu.edu/RECONS/>. To detect stars
    out to 300 ly would obviously be much harder, since they would be up to
    ~100 times dimmer, and there will be ~1000 times as many stars to survey.

    The 2MASS survey is attempting to detect all objects brighter than
    1 mJy in the J, H, and K_s infrared bands,
    <http://www.ipac.caltech.edu/2mass/overview/about2mass.html>;
    this survey will hopefully detect many nearby L- and T-type brown dwarves,
    <http://www.ipac.caltech.edu/2mass/overview/dwarfs.html>.
    but will represent an exhaustive survey of them.

    CORRECTION --- I wrote:


    The last line above should read: "Will _NOT_ represent an exhaustive survey
    of them"... :-(
