Magnetic field topology and chemical spot distributions in the extreme Ap star HD 75049
O. Kochukhov, N. Rusomarov, J. A. Valenti +7
Intermediate-mass, magnetic chemically peculiar (Ap) stars provide a unique opportunity to study the topology of stellar magnetic fields in detail and to investigate magnetically d…
Are there tangled magnetic fields on HgMn stars?
O. Kochukhov, V. Makaganiuk, N. Piskunov +7
Several recent spectrophotometric studies failed to detect significant global magnetic fields in late-B HgMn chemically peculiar stars, but some investigations have suggested the p…
Magnetically Controlled Accretion on the Classical T Tauri Stars GQ Lupi and TW Hydrae
C. M. Johns-Krull, W. Chen, J. A. Valenti +8
We present high spectral resolution () Stokes polarimetry of the Classical T Tauri stars (CTTSs) GQ Lup and TW Hya obtained with the polarimetric upgrade to th…
Doppler imaging of HD 184905
V. A. Makaganiuk, G. Barisevičius
A Doppler imaging analysis of HD 184905 is pre-sented. Based on time series of high resolution and high signal-to-noise ratio observations we have refined vsini and v_rad with the…
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…
