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…
No magnetic field in the spotted HgMn star mu Leporis
O. Kochukhov, V. Makaganiuk, N. Piskunov +7
Chemically peculiar stars of the mercury-manganese (HgMn) type represent a new class of spotted late-B stars, in which evolving surface chemical inhomogeneities are apparently unre…
Data Reduction Techniques for High Contrast Imaging Polarimetry. Applications to ExPo
H. Canovas, M. Rodenhuis, S. V. Jeffers +2
Imaging polarimetry is a powerful tool for detecting and characterizing exoplanets and circumstellar environments. Polarimetry allows a separation of the light coming from an unpol…
First detection of linear polarization in the line profiles of active cool stars
O. Kochukhov, V. Makaganiuk, N. Piskunov +6
The application of high-resolution spectropolarimetry has led to major progress in understanding the magnetism and activity of late-type stars. During the last decade, magnetic fie…
Chemical spots in the absence of magnetic field in the binary HgMn star 66 Eridani
V. Makaganiuk, O. Kochukhov, N. Piskunov +7
According to our current understanding, a subclass of the upper main sequence chemically peculiar stars, called mercury-manganese (HgMn), is non-magnetic. Nevertheless, chemical in…
