Abstract:
O stars are excellent tracers of the intervening ISM because of their
high luminosity, blue intrinsic SED, and relatively featureless
spectra. We are currently conducting the Galactic O-Star Spectroscopic
Survey (GOSSS), which is generating a large sample of O stars with
accurate spectral types within several kpc of the Sun.
We aim to obtain a global picture of the properties of dust extinction
in the solar neighborhood based on optical-NIR photometry of O stars
with accurate spectral types.
We have processed a carefully selected photometric set with the
CHORIZOS code to measure the amount [E(4405-5495)] and type
[R5495] of extinction towards 562 O-type stellar systems. We have
tested three different families of extinction laws and analyzed our
results with the help of additional archival data.
Description:
File table1.dat contains the values for the amount and type of
extinction for 562 Galactic O stars, as well as their corrected V
magnitudes, their spectroscopic parallaxes uncorrected for binarity
and a comparison between the quality of the fits using the CCM
(Cardelli et al., 1989ApJ...345..245C 1989ApJ...345..245C), F99 (Fitzpatrick,
1999PASP..111...63F 1999PASP..111...63F), and MA14 (Maiz Apellaniz et al.,
2014A&A...564A..63M 2014A&A...564A..63M) families of extinction laws.
