Magnetic field topology of the cool, active, short-period binary system Coronae Borealis
L. Rosén, O. Kochukhov, E. Alecian +4
The goal of this work is to study the cool, active binary star CrB, focussing on its magnetic field. We used Stokes data from the twin spectropolarimeters Narval at the…
Magnetic fields of young solar twins
L. Rosén, O. Kochukhov, T. Hackman +1
The goal of this work is to study the magnetic fields of six young solar-analogue stars both individually, and collectively, to search for possible magnetic field trends with age.…
Zeeman-Doppler imaging of active young solar type stars
Thomas Hackman, Jyri Lehtinen, Lisa Rosén +2
By studying young magnetically active late-type stars, i.e. analogues to the young Sun, one can draw conclusions on the evolution of the solar dynamo. We determine the topology of…
First Zeeman Doppler imaging of a cool star using all four Stokes parameters
Lisa Rosén, Oleg Kochukhov, Gregg A. Wade
Magnetic fields are ubiquitous in active cool stars but they are in general complex and weak. Current Zeeman Doppler imaging (ZDI) studies of cool star magnetic fields chiefly empl…
Zeeman Doppler imaging of a cool star using line profiles in all four Stokes parameters for the first time
L. Rosén, O. Kochukhov, G. A. Wade
Magnetic fields in cool stars are ubiquitous but can still be challenging to characterize due to their complexity and relatively low strength. The polarization signature amplitudes…
How reliable is Zeeman Doppler Imaging without simultaneous temperature reconstruction?
Lisa Rosén, Oleg Kochukhov
Aims: The goal of this study is to perform numerical tests of Zeeman Doppler Imaging (ZDI) to asses whether correct reconstruction of magnetic fields is at all possible without tak…
