Surface magnetism of cool stars
O. Kochukhov, P. Petit, K. G. Strassmeier +10
Magnetic fields are essential ingredients of many physical processes in the interiors and envelopes of cool stars. Yet their direct detection and characterisation is notoriously di…
B field in OB stars (BOB): The outstandingly strong magnetic field in the evolved He-strong star CPD-62 2124
N. Castro, L. Fossati, S. Hubrig +12
The origin and evolution of magnetism in OB stars is far from being well understood. With approximately 70 magnetic OB stars known, any new object with unusual characteristics may…
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…
Time-series Doppler images and surface differential rotation of the effectively-single rapidly-rotating K-giant KU Pegasi
Zs. Kővári, A. Künstler, K. G. Strassmeier +6
According to most stellar dynamo theories, differential rotation (DR) plays a crucial role for the generation of toroidal magnetic fields. Numerical models predict surface differen…
Time-series Doppler imaging of the red giant HD 208472. Active longitudes and differential rotation
O. Özdarcan, T. A. Carroll, A. Künstler +4
HD 208472 is among the most active RS~CVn binaries with cool starspots. Decade-long photometry has shown that the spots seem to change their longitudinal appearance with a period o…
Anti-solar differential rotation on the active sub-giant HU Virginis
G. Harutyunyan, K. G. Strassmeier, A. Künstler +2
Measuring surface differential rotation (DR) on different types of stars is important when characterizing the underlying stellar dynamo. It has been suggested that anti-solar DR la…
