Membership, binarity and accretion among very low-mass stars and brown dwarfs of the Sigma Orionis cluster
M. J. Kenyon, R. D. Jeffries, Tim Naylor +2
Intermediate resolution (R=7000) spectroscopy is presented for 76 photometrically selected very low mass (0.04<M<0.3M_{sun}) candidate members of the Sigma Orionis cluster. More th…
Photospheric magnetic field and surface differential rotation of the FK Com star HD 199178
P. Petit, J. -F. Donati, J. M. Oliveira +11
We present spectropolarimetric observations of the FK Com star HD 199178 obtained between 1998 December and 2003 August at the Telescope Bernard Lyot (Observatoire du Pic du Midi,…
Multi-Site observations of SU Aurigae
Y. C. Unruh, J. -F. Donati, J. M. Oliveira +20
We present results from the 1996 MUSICOS (MUlti-SIte COntinuous Spectroscopy) campaign on the T Tauri star SU Aurigae. We find a 2.7-d periodicity in the He I (587.6 nm) line and s…
