Spectral Synthesis of Spectral Populations using Balmer Linespectrum to synthetic spectra built by adding contributions of stars (or star clusters) of various ages. When the population is young, its visible spectrum is dominated by Balmer lines. These lines have rarely been used for spectral synthesis because Balmer lines in emission are superimposed to the c

Radiation Driven Winds of Hot Stars: Theory of O-Star Atmospheres as a Spectroscopic Toolms relating to the fomation of UV line spectra the use of accurate atomic data, the inclusion of EUV radiation by shock heated matter, the simulation of photospheric line blocking. A new tool for O-star diagnostics is presented. This is based on the use of wind models to calculate synthetic high res

The Chemical Composition of B-supergiant Atmospheresst luminous Ia stars is close to its equilibrium value. The is also some evidence for more moderate CN abundance anomalies in the B2Ib and B2II supergiants. These results, together with other recent work, imply that the effects of the CNO bi-cycle on the composition of B-supergiant atmospheres are m

LTE and NLTE Abundances in A-Supergiants a Test of Their Evolutionary Statuses between the scenarios depend on the input assumptions for several physical parameters, ., treatments for convection parameters and mass loss rates. A review of the predictions of evolution calculations for 10–30 solar mass stars is given by Fitzpatrick & Garmany (1991).
