Hot HB stars in globular clusters - Physical parameters and consequences for theory. V. Radiative levitation versus helium mixing
S. Moehler, A. V. Sweigart, W. B. Landsman +1
Atmospheric parameters (effective temperature Teff, surface gravity log g), masses and helium abundances are derived for 42 hot horizontal branch (HB) stars in the globular cluster…
The Schweizer-Middleditch star revisited
M. R. Burleigh, U. Heber, D. O'Donoghue +1
We have re-observed and re-analysed the optical spectrum of the Schweizer-Middleditch star, a hot subdwarf which lies along almost the same line-of-sight as the centre of the histo…
First VLT spectra of white dwarfs in a globular cluster
S. Moehler, U. Heber, R. Napiwotzki +2
We present the first spectra obtained with the Very Large Telescope for white dwarfs in a globular cluster. Estimates of atmospheric parameters are obtained and compared to evoluti…
