J/BaltA/11/1    Interstellar extinction curves of OB stars   (Wegner 2002)

Atlas of interstellar extinction curves of OB stars covering the whole available wavelength range. Wegner W. <Baltic Astronomy, 11, 1 (2002)> =2002BaltA..11....1W

The data were taken from the ANS photometric catalogue (Cat. II/97) and from the compilations of IR photometric measurements. The data curves have been obtained with the aid of "artificial standards" Papaj et al. (1993A&A...273..575P) and Wegner (1994MNRAS.270..229W, 1995, Interstellar Absorption Structures in the Direction of Nearby OB stars, Wyd. Uczelniane WSP, Bydgoszcz, p. 1-383). The visual magnitudes and spectral classifications of O and B type stars with EB-V≥0.05 were taken from the SIMBAD database. The curves are given in the form of plots and tables Eλ-V/EB-V versus 1/λ. The observed variety of extinction laws among slightly reddened stars is apparently due to the various physical parameters of interstellar clouds. File Summary:
