Stauffer et al. (2010) provides precise J2000, epoch 2000 coordinates, and cross-identifications to sources in the 2MASS Point Source Catalog for nearly all stars in the Gliese, Gliese-Jahreiss, and Woolley catalogs of nearby stars. The GJ Stars interactive table contains data from Table 1 of Stauffer et al. (2010).
The following table lists all of the data columns in the Gliese-Jahreiss (GJ) Stars table (gjstars
) that can be accessed using the GJ Stars interactive table. These column names can also be specified in pre-filtered table queries.
Database Column Name |
Table Label | Description | Displayed String Name | Limit Column |
---|---|---|---|---|
gj_name† | Name |
Star name from the nearby star catalog:
|
||
alt_name† | Alternate Name | Star name when star appears in more than one of the nearby star catalog. For stars with both Gliese and Woolley names, the Wo name is listed; otherwise star name from the Hipparcos catalog, when available. | ||
rastr† | RA [sexagesimal] | Right ascension of the star for equinox and epoch 2000 in sexagesimal format. | ||
decstr† | Dec [sexagesimal] | Declination of the star for equinox and epoch 2000 in sexagesimal format. | ||
ra | RA [decimal degrees] | Right ascension of the star for equinox and epoch 2000 in decimal degrees. | ||
dec | Dec [decimal degrees] | Declination of the star for equinox and epoch 2000 in decimal degrees. | ||
pmra† | Proper Motion (RA) [mas/yr] | Angular change in right ascension over time as seen from the center of mass of the Solar System. | pmrastr | pmralim |
pmdec† | Proper Motion (Dec) [mas/yr] | Angular change in declination over time as seen from the center of mass of the Solar System. | pmdecstr | pmdeclim |
tm_name† | 2MASS Name | Name of the star as given by the 2MASS catalog. | ||
j2m† | J-band (2MASS) [mag] | Brightness of the star as measured using the J (2MASS) band in units of magnitudes. | ||
h2m† | H-band (2MASS) [mag] | Brightness of the star as measured using the H (2MASS) band in units of magnitudes. | ||
k2m† | Ks-band (2MASS) [mag] | Brightness of the star as measured using the Ks (2MASS) band in units of magnitudes. | ||
gj_comment† | Comments |
Comment flags:
|
||
coordsrc† | Coordinate Source | Source of the position of the star, either the Hipparcos or 2MASS catalogs, or an additional source such as the LSPM catalog (Lepine et al. 2005) |
