Magnetic fields in O-type stars measured with FORS1 at the VLT
S. Hubrig, M. Schoeller, R. S. Schnerr +4
The presence of magnetic fields in O-type stars has been suspected for a long time. The discovery of such fields would explain a wide range of well documented enigmatic phenomena i…
New insights into the nature of the peculiar star theta Carinae
S. Hubrig, M. Briquet, T. Morel +3
We acquired high resolution spectroscopic and low resolution spectropolarimetric observations to achieve the following goals: a) to improve the orbital parameters to allow a more i…
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…
Detection of variable Si II, Mn II and Fe II emission lines in the magnetic Bp star a Centauri
S. Hubrig, J. F. Gonzalez
The nature of non-variable high-excitation emission lines detected in the optical spectra of normal late-B type and chemically peculiar HgMn and PGa stars is still poorly understoo…
Heavy Calcium in CP Stars
C. R. Cowley, S. Hubrig, F. Castelli +2
Large wavelength shifts of infrared triplet lines of Ca II have been observed in the spectra of HgMn and magnetic Ap stars. They have been attributed to the heavy calcium isotopes,…
