B fields in OB stars (BOB): on the detection of weak magnetic fields in the two early B-type stars beta CMa and epsilon CMa
L. Fossati, N. Castro, T. Morel +15
Within the context of the "B fields in OB stars (BOB)" collaboration, we used the HARPSpol spectropolarimeter to observe the early B-type stars beta CMa (HD44743; B1 II/III) and ep…
Antisolar differential rotation of the K1-giant sigma Geminorum revisited
Zs. Kovari, L. Kriskovics, A. Künstler +6
Context. Surface differential rotation and other global surface flows on magnetically active stars are among the observable manifestations of the stellar dynamo working underneath.…
Probing the Structure of the Accretion Region in a Sample of Magnetic Herbig Ae/Be Stars
M. A. Pogodin, J. A. Cahuasqui, N. A. Drake +10
We present the results of a study of the temporal behaviour of several diagnostic lines formed in the region of the accretion-disk/star interaction in the three magnetic Herbig Ae…
Abundance analysis, spectral variability, and search for the presence of a magnetic field in the typical PGa star HD19400
S. Hubrig, F. Castelli, J. F. Gonzalez +6
The aim of this study is to carry out an abundance determination, to search for spectral variability and for the presence of a weak magnetic field in the typical PGa star HD19400.…
B fields in OB stars (BOB): The discovery of a magnetic field in a multiple system in the Trifid Nebula, one of the youngest star forming regions
S. Hubrig, L. Fossati, T. A. Carroll +12
Recent magnetic field surveys in O- and B-type stars revealed that about 10% of the core-hydrogen-burning massive stars host large-scale magnetic fields. The physical origin of the…
Detecting and quantifying stellar magnetic fields -- Sparse Stokes profile approximation using orthogonal matching pursuit
T. A. Carroll, K. G. Strassmeier
In the recent years, we have seen a rapidly growing number of stellar magnetic field detections for various types of stars. Many of these magnetic fields are estimated from spectro…
