Discovery of the longest-period rapidly oscillating Ap star HD177765
D. Alentiev, O. Kochukhov, T. Ryabchikova +3
We present the discovery of a long-period, rapidly oscillating Ap star, HD177765. Using high-resolution time-series observations obtained with UVES at the ESO VLT telescope, we fou…
Magnetic field measurements and their uncertainties: the FORS1 legacy
S. Bagnulo, J. D. Landstreet, L. Fossati +1
During the last decade, the FORS1 instrument of the ESO VLT has been extensively used to study stellar magnetism. A number of interesting discoveries of magnetic fields in several…
First HARPSpol discoveries of magnetic fields in massive stars
E. Alecian, O. Kochukhov, C. Neiner +14
In the framework of the Magnetism in Massive Stars (MiMeS) project, a HARPSpol Large Program at the 3.6m-ESO telescope has recently started to collect high-resolution spectropolari…
Characterizing the magnetic fields of the first tau Sco analogues
V. Petit, O. Kochukhov, D. L. Massa +3
The B0.2 V magnetic star tau Sco stands out from the larger population of massive OB stars due to its high X-ray activity, peculiar wind diagnostics and complex magnetic field. Rec…
Magnetism, chemical spots, and stratification in the HgMn star phi Phoenicis
V. Makaganiuk, O. Kochukhov, N. Piskunov +7
Mercury-manganese (HgMn) stars have been considered as non-magnetic and non-variable chemically peculiar (CP) stars for a long time. However, recent discoveries of the variability…
Magnetic Field and Atmospheric Chemical Abundances of the Magnetic Ap Star HD 318107
J. D. Bailey, J. D. Landstreet, S. Bagnulo +5
New spectra have been obtained with the ESPaDOnS spectropolarimeter supplemented with unpolarised spectra from the ESO UVES, UVES-FLAMES, and HARPS spectrographs of the very peculi…
