An automatic procedure for a determination of the effective temperature and gravity. Application to 100 O-type stars.
Abstract
We have developed an automatic procedure to determine Teff and log g from the comparison of observational data with their theoretical values. After a description of the method we compare our results for a sample of 100 O-type stars with the classifications of Conti and Walborn and with the determinations of Morrison by photometric indices. The agreement is fair and we present a HR diagram for O-type stars based on our data.
