Slingshot prominences: coronal structure, mass loss and spin down
M. Jardine, A. Collier Cameron, J. -F. Donati +1
The structure of a star's coronal magnetic field is a fundamental property that governs the high-energy emission from the hot coronal gas and the loss of mass and angular momentum…
Does magnetic field impact tidal dynamics inside the convective zone of low-mass stars along their evolution?
A. Astoul, S. Mathis, C. Baruteau +5
The dissipation of the kinetic energy of wave-like tidal flows within the convective envelope of low-mass stars is one of the key physical mechanisms that shapes the orbital and ro…
The Mass-Activity relationships in M and K dwarfs. I. Stellar parameters of our sample of M and K dwarfs
Eric R. Houdebine, D. J. Mullan, J. G. Doyle +3
Empirical correlations between stellar parameters such as rotation or radius and magnetic activity diagnostics require estimates of the effective temperatures and the stellar radii…
Sliced Inverse Regression: application to fundamental stellar parameters
S. Kassounian, M. Gebran, F. Paletou +1
We present a method for deriving stellar fundamental parameters. It is based on a regularized sliced inverse regression (RSIR). We first tested it on noisy synthetic spectra of A,…
