Detection of a large-scale organized 2 kG order magnetic field in the Herbig Ae star HD179218
S. P. Järvinen, S. Hubrig, M. Schöller +5
While about two dozen Herbig Ae/Be stars have been reported to be magnetic, only two of them, HD101412 and HD190073, have had their magnetic field geometries studied in the past. T…
The magnetic fields in Be stars are stronger than previously suggested
S. Hubrig, S. P. Järvinen, M. Schöller +1
Recent observational studies suggest that Be stars most likely are formed through the process of mass transfer in binary systems. In view of the wide consensus that the origin of t…
Searching for magnetic fields in pulsating A-type stars: the discovery of a strong field in the probable delta Sct star HD340577 and a null result for the gamma Dor star HR8799
S. Hubrig, S. P. Jarvinen, J. D. Alvarado-Gomez +2
Numerous delta Sct and gamma Dor pulsators are identified in the region of the Hertzsprung-Russell diagram that is occupied by chemically peculiar magnetic Ap stars. The connection…
The magnetic, spectroscopic, and photometric variability of the Wolf-Rayet star WR55
S. P. Järvinen, S. Hubrig, R. Jayaraman +2
Studies of magnetic fields in the most evolved massive stars, the Wolf-Rayet stars, are of special importance because they are progenitors of certain types of supernovae. The first…
Magnetic field measurements of sharp-lined Ap stars
S. P. Järvinen, S. Hubrig, R. Jayaraman +2
Previous observations suggested that Ap and Bp stars exhibit a bimodal distribution of surface magnetic field strengths and that actually only few or no stars exist with magnetic d…
The evolutionary state of the chemically peculiar members of the open cluster NGC2516
N. V. Kharchenko, A. E. Piskunov, S. Hubrig +1
We aim at establishing safe membership and evolutionary status of 11 chemically peculiar (CP) stars that are residing in the domain of the open cluster NGC2516 and are frequently r…
Detection of anomalous element distribution in the extremely slowly rotating magnetic O9.7 V star HD 54879
S. P. Järvinen, S. Hubrig., M. Schöller +4
The O9.7 V star HD 54879 is currently the only massive magnetic star whose magnetic field geometry and rotation period are not constrained. Over the last three years, we gathered a…
B fields in OB stars (BOB): Concluding the FORS2 observing campaign
M. Schoeller, S. Hubrig, L. Fossati +16
The "B fields in OB stars" (BOB) collaboration is based on an ESO Large Programme, to study the occurrence rate, properties, and ultimately the origin of magnetic fields in massive…
B fields in OB stars (BOB): low-resolution FORS2 spectropolarimetry of the first sample of 50 massive stars
L. Fossati, N. Castro, M. Schoeller +10
Within the context of the collaboration "B fields in OB stars (BOB)", we used the FORS2 low-resolution spectropolarimeter to search for a magnetic field in 50 massive stars, includ…
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…
Weak magnetic fields in central stars of planetary nebulae?
M. Steffen, S. Hubrig, H. Todt +4
It is not yet clear whether magnetic fields play an essential role in shaping planetary nebulae (PNe), or whether stellar rotation alone and/or a close binary companion can account…
Characterising the magnetic fields of the Herbig Ae/Be stars HD97048, HD150193, HD176386, and MWC480
S. Hubrig, M. Schoeller, I. Ilyin +6
Our knowledge of the presence and the role of magnetic fields in intermediate-mass pre-main-sequence stars remains very poor. We present the magnetic properties of four Herbig Ae/B…
The strong magnetic field of the large-amplitude beta Cephei pulsator V1449 Aql
S. Hubrig, I. Ilyin, M. Briquet +5
Only for very few beta Cephei stars has the behaviour of the magnetic field been studied over the rotation cycle. During the past two years we have obtained multi-epoch polarimetri…
Rotationally modulated variations and the mean longitudinal magnetic field of the Herbig Ae star HD 101412
S. Hubrig, Z. Mikulasek, J. F. Gonzalez +8
Despite of the importance of magnetic fields for the full understanding of the properties of accreting Herbig Ae/Be stars, these fields have scarcely been studied over the rotation…
The nature of the recent extreme outburst of the Herbig Be/FU Ori binary Z CMa
T. Szeifert, S. Hubrig, M. Schöller +3
Z CMa is a binary system which consists of two young stars: A Herbig AeBe component "Z CMa NW" embedded in a dust cocoon and a less massive component "Z CMa SE", which is classifie…
