Variable magnetic field geometry of the young sun HN Peg (HD 206860)
S. Boro Saikia, S. V. Jeffers, P. Petit +3
The large-scale magnetic field of solar-type stars reconstructed from their spectropolarimetric observations provide important insight into their underlying dynamo processes.We aim…
Stellar magnetism: empirical trends with age and rotation
A. A. Vidotto, S. G. Gregory, M. Jardine +12
We investigate how the observed large-scale surface magnetic fields of low-mass stars (~0.1 -- 2 Msun), reconstructed through Zeeman-Doppler imaging (ZDI), vary with age t, rotatio…
Modelling the Hidden Magnetic Field of Low-Mass Stars
P. Lang, M. Jardine, J. Morin +4
Zeeman-Doppler imaging is a spectropolarimetric technique that is used to map the large-scale surface magnetic fields of stars. These maps in turn are used to study the structure o…
PolarBase: a data base of high resolution spectropolarimetric stellar observations
P. Petit, T. Louge, S. Théado +5
PolarBase is an evolving data base that contains all stellar data collected with the ESPaDOnS and NARVAL high-resolution spectropolarimeters, in their reduced form, as soon as they…
