Stellar mass ejections
M. Jardine, J. -F. Donati, S. G. Gregory
It has been known for some time now that rapidly-rotating solar-like stars possess the stellar equivalent of solar prominences. These may be three orders of magnitude more massive…
Large-scale magnetic topologies of M dwarfs
J. Morin, J. -F. Donati, X. Delfosse +2
We present here the first results of a spectropolarimetric analysis of a small sample (about 20) of active stars ranging from spectral type M0 to M8, which are either fully-convect…
Large-scale magnetic topologies of early M dwarfs
JF Donati, J Morin, P Petit +12
We present here additional results of a spectropolarimetric survey of a small sample of stars ranging from spectral type M0 to M8 aimed at investigating observationally how dynamo…
Radio emission from exoplanets: the role of the stellar coronal density and magnetic field strength
M. Jardine, A. C. Cameron
The search for radio emission from extra-solar planets has so far been unsuccessful. Much of the effort in modelling the predicted emission has been based on the analogy with the w…
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…
X-Ray flares in Orion Young Stars. II. Flares, Magnetospheres, and Protoplanetary Disks
Konstantin V. Getman, Eric D. Feigelson, Giuseppina Micela +3
We study the properties of powerful X-ray flares from 161 pre-main sequence (PMS) stars observed with the Chandra X-ray Observatory in the Orion Nebula region. Relationships betwee…
