Zeeman-Doppler Imaging of Late-Type Stars -- The Surface Magnetic Field of II Peg
T. A. Carroll, M. Kopf, I. Ilyin +1
Late-type stars in general possess complicated magnetic surface fields which makes their detection and in particular their modeling and reconstruction challenging. In this work we…
Multifrequency variability of the blazar AO 0235+164. The WEBT campaign in 2004-2005 and long-term SED analysis
C. M. Raiteri, M. Villata, M. Kadler +3
A huge multiwavelength campaign targeting the blazar AO 0235+164 was organized by the Whole Earth Blazar Telescope (WEBT) in 2003-2005 to study the variability properties of the so…
On the CO Near-IR Band and the Line Splitting Phenomenon in the Yellow Hypergiant Rho Cassiopeiae
N. Gorlova, A. Lobel, A. Burgasser +3
We report on multi-epoch optical and near-infrared spectroscopy around the first overtone ro-vibrational band of CO in the pulsating yellow hypergiant Rho Cas, one of the most mass…
Supernova 2006aj and the associated X-Ray Flash 060218
J. Sollerman, A. O. Jaunsen, J. P. U. Fynbo +23
We have studied the afterglow of the gamma-ray burst (GRB) of February 18, 2006. This is a nearby long GRB, with a very low peak energy, and is therefore classified as an X-ray Fla…
Mass-loss and Recent Spectral Changes in the Yellow Hypergiant Rho Cassiopeiae
A. Lobel, J. Aufdenberg, I. Ilyin +1
The yellow hypergiant Rho Cassiopeiae (F-G Ia0) has recently become very active with a tremendous outburst event in the fall of 2000. During the event the pulsating supergiant dimm…
Magnetic fields in Herbig Ae stars
S. Hubrig, M. Schoeller, R. V. Yudin
Herbig Ae stars are young A-type stars in the pre-main sequence evolutionary phase with masses of ~1.5-3 M_o. They show rather intense surface activity (Dunkin et al. 1997) and inf…
