Magnetic fields of cool giant and supergiant stars: models versus observations
Heidi Korhonen
The recent years have brought great advances in our knowledge of magnetic fields in cool giant and supergiant stars. For example, starspots have been directly imaged on the surface…
Contemporaneous Imaging Comparisons of the Spotted Giant Geminorum Using Interferometric, Spectroscopic, and Photometric Data
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +8
Nearby, active stars with relatively rapid rotation and large starspot structures offer the opportunity to compare interferometric, spectroscopic, and photometric imaging technique…
No Sun-like dynamo on the active star Andromedae from starspot asymmetry
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +12
Sunspots are cool areas caused by strong surface magnetic fields inhibiting convection. Moreover, strong magnetic fields can alter the average atmospheric structure, degrading our…
Magnetic field geometry and chemical abundance distribution of the He-strong star CPD -57 3509
S. Hubrig, N. Przybilla, H. Korhonen +9
The magnetic field of CPD -57 3509 was recently detected in the framework of the BOB (B fields in OB stars) collaboration. We acquired low-resolution spectropolarimetric observatio…
