Large-scale magnetic topologies of mid-M dwarfs
J. Morin, J. -F. Donati, P. Petit +13
We present in this paper the first results of a spectropolarimetric analysis of a small sample (~ 20) of active stars ranging from spectral type M0 to M8, which are either fully-co…
Strength distribution of solar magnetic fields in photospheric quiet Sun regions
J. C. Ramirez Velez, A. Lopez Ariste, M. Semel
The magnetic topology of the solar photosphere in its quietest regions is hidden by the difficulties to disentangle magnetic flux through the resolution element from the field stre…
PCA detection and denoising of Zeeman signatures in stellar polarised spectra
M. J. Martinez Gonzalez, A. Asensio Ramos, T. A. Carroll +3
Our main objective is to develop a denoising strategy to increase the signal to noise ratio of individual spectral lines of stellar spectropolarimetric observations. We use a multi…
