First time-series optical photometry from Antarctica
K. G. Strassmeier, R. Briguglio, T. Granzer +11
Beating the Earth's day-night cycle is mandatory for long and continuous time-series photometry and had been achieved with either large ground-based networks of observatories at di…
A search for pulsational line profile variations in the delta Scuti star HD21190 and the Ap Sr star HD218994
J. F. Gonzalez, S. Hubrig, I. Savanov
We present the results of our recent search for pulsational line profile variations in high time resolution UVES spectra of the most evolved Ap star known, the delta Scuti star HD2…
Discovery of pulsational line profile variations in the delta Scuti star HD21190 and in the Ap Sr star HD218994
J. F. Gonzalez, S. Hubrig, D. W. Kurtz +2
Asteroseismology has the potential to provide new insights into the physics of stellar interiors. We have obtained UVES high time resolution observations of the delta Scuti star HD…
A study of the magnetic helium variable emission-line star HD 125823
S. Hubrig, N. Nesvacil, F. Gonzalez +2
The 5.9 M_sun star HD 125823 is a striking helium variable with a period of 8.82 d, ranging in helium spectral type from He-strong B2 to He-weak B8. For the first time we present h…
Inhomogeneous surface distribution of chemical elements in the eclipsing binary AR Aur: A new challenge for our understanding of HgMn stars
S. Hubrig, J. F. Gonzalez, I. Savanov +4
We present the results of a high spectral resolution study of the eclipsing binary AR Aur. AR Aur is the only known eclipsing binary with a HgMn primary star exactly on the ZAMS an…
Vertical distribution of chromium in the atmospheres of HgMn stars
I. Savanov, S. Hubrig
We use multiplet 30 Cr II lines in the wings of H_beta to test the hypothesis of an anomalous concentration of Cr in the upper layers of the atmospheres of a sample of 10 HgMn star…
