J/other/SAAOC/15.53 Southern reddened luminous stars. II. (Kilkenny 1993) ================================================================================ A Study of Reddened Luminous Stars in the Southern Milky Way II. Hbeta Photometry, Reddening and Distances Kilkenny D. =1993SAAOC..15...53K (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Stars, luminous ; Photometry, H-beta ; Reddening ; Stars, distances Abstract: H{beta} photometry is given for 263 reddened and very reddened stars from the Stephenson & Sanduleak (1971, Cat. ) catalogue of Luminous Stars in the Southern Milky Way (LSS). The results are combined with the uvby photometry presented in Paper I to determine reddenings, E(b-y), and distances for the stars and to estimate the spectral types and luminosity classes from derived T_eff_ and M_V_ values.
