The surface gravities of cool dwarf stars revisited
On the base of high-resolution spectra and standard model atmosphere analyses we propose to employ the pressurebroadenedMg Ib lines to derive the gravity parameter for F and G stars. These lines are advocated to be a much more robust and reliable tracer compared to the ionization equilibrium of, say, Fe I/Fe II, which is susceptible to overionization effects and uncertainties in the temperature...
متن کاملSurface gravities of very metal-poor stars from Hipparcos parallaxes
Wediscuss some consequences for the determination of the surface gravity parameter of very metal-poor halo dwarfs in the new light shed upon these objects from the Hipparcos astrometry. Whereas it has become clear that standard spectroscopic LTE iron ionization equilibria are prone to systematic errors, in the sense, that stages of evolution are predicted that are actually not yet reached, the ...
متن کاملThe Effective Temperatures of Hot Stars
We review the eeective temperature scale of hot (10kK) stars, including results from direct, continuum and ionization equilibrium techniques. We discuss the impact of recent developments in theoretical model atmospheres for OB subdwarfs, dwarfs and supergiants, white dwarfs and Wolf Rayet stars and present a revised T ee scale for OB stars. Direct techniques coupled with Kurucz model atmosphere...
متن کاملThe Effective Temperatures of O-type Stars from UV spectroscopy
We present an analysis of high resolution spectra in the far-UV − UV range (∼905-2000Å) with non-LTE, spherical, hydrodynamical, line-blanketed models, of three O-type Galactic stars, and derive their photospheric and wind parameters. These data extend previously analyzed samples and fill a gap in spectral type coverage. The combined sample confirms a revised (downward) Teff scale with respect ...
متن کاملMasses and Gravities of Blue Horizontal Branch ( Bhb ) Stars
Previous spectroscopic analyses of Blue Horizontal Branch (BHB) stars in six globular clusters revealed too low masses in four clusters when compared to canonical evolutionary theory, while the masses of the BHB stars in NGC 6752 and M 5 are found to be consistent with theory. We recalculated BHB star masses using new cluster distances derived by Reid (1997a,b) from Hipparcos parallaxes of loca...
