J/A+AS/128/309 ubvy-beta photometry of CarOB1 and CarOB2 stars (Kaltcheva 1998) ================================================================================ Stroemgren and H{beta} photometry of OB stars in the region of the Carina Spiral Feature Kaltcheva N.T. =1998A&AS..128..309K (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Stars, OB ; Photometry, uvby, beta ; Associations, stellar Keywords: stars: early-type - stars: distances - Galaxy: structure - stars: HR diagram Abstract: Stromgren and H{beta} photometry of 130 stars in the Carina section of the Milky Way is presented. The color excesses and the distances of all stars are obtained. A good agreement is found between the CM and HR diagrams and the spatial distribution of these stars.
