V/116                     Galactic O star catalog        (Maiz-apellaniz+, 2004)

A galactic O star catalog. Maiz-Apellaniz J., Walborn N.R., Galue H.A., Wei L.H. <Astrophys. J. Suppl. Ser., 151, 103-148 (2004)> =2004ApJS..151..103M
ADC_Keywords: Stars, O ; MK spectral classification ; Photometry, UBV ; Photometry, infrared ; Photometry, uvby Keywords: binaries: general - catalogs - open clusters and associations: general - stars: distances - stars: early-type - stars: fundamental parameters Abstract: We have produced a catalog of 378 Galactic O stars with accurate spectral classifications that is complete for V<8 but includes many fainter stars. The catalog provides cross-identifications with other sources; coordinates (obtained in most cases from Tycho-2 data); astrometric distances for 24 of the nearest stars; optical (Tycho-2, Johnson, and Stroemgren) and NIR photometry; group membership, runaway character, and multiplicity information; and a Web-based version with links to on-line services.

Note (2): Binary status: SB1O = well-known single-lined spectroscopic binary; SB20 = well-known double-lined spectroscopic binary; SB10? = uncertain single-lined spectroscopic binary; SB20? = uncertain double-lined spectroscopic binary; C = apparent constant radial velocity; U = unknown status; E = eclipsing or ellipsoidal variable. Note (3): Uncertain determinations are indicated by a colon. Note (4): Based on the following recipe. 1] Stars listed as runaways in Hoogerwerf et al., 2001A&A...365...49H or Mason et al., 1998AJ....115..821M, have a "yes" 2] Other stars in clusters/associations or stars in Mason et al., 1998AJ....115..821M, not listed as runaways have a "no". 3] Other stars with "Field:"' in the previous column have a "no:".

Global notes: Note (G1): Produced according to the criteria recommended by the IAU Lortet et al. (1994A&AS..107..193L). The first character is always a G (indicates Galactic coordinates), the next six express the Galactic longitude in degrees in the format LLL.ll, the eighth character is the latitude sign, the next five express the absolute value of the Galactic latitude in degrees in the format BB.bb, the fourteenth is an underscore, and the fifteenth and sixteenth are a running number to differentiate stars which would otherwise have the same catalog number. Note that a previous web-based version of this catalog used a different nomenclature with arcminutes instead of decimal degrees.
