Imaging the circumstellar environment of the young T Tauri star SU Aurigae
S. V. Jeffers, M. Min, H. Canovas +2
The circumstellar environments of classical T Tauri stars are challenging to directly image because of their high star-to-disk contrast ratio. One method to overcome this is by usi…
Three-dimensional magnetic and abundance mapping of the cool Ap star HD 24712 I. Spectropolarimetric observations in all four Stokes parameters
N. Rusomarov, O. Kochukhov, N. Piskunov +8
High-resolution spectropolarimetric observations provide simultaneous information about stellar magnetic field topologies and three-dimensional distributions of chemical elements.…
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…
The color dependent morphology of the post-AGB star HD161796
M. Min, S. V. Jeffers, H. Canovas +3
Context. Many protoplanetary nebulae show strong asymmetries in their surrounding shell, pointing to asymmetries during the mass loss phase. Questions concerning the origin and the…
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…
