On the chromospheric activity of stars with planets
B. L. Canto Martins, M. L. das Chagas, S. Alves +3
Context. Signatures of chromospheric activity enhancement have been found for a dozen stars, pointing to a possible star-planet interaction. Nevertheless in the coronal activity re…
The circumstellar envelope of IRC+10216 from milli-arcsecond to arcmin scales
I. C. Leao, Patrick De Laverny, D. Mekarnia +2
Aims.Analysis of the innermost regions of the carbon-rich star IRC+10216 and of the outer layers of its circumstellar envelope have been performed in order to constrain its mass-lo…
A snapshot of the inner dusty regions of a RCrB-type variable
I. C. Leao, Patrick De Laverny, O. Chesneau +2
R Coronae Borealis variable stars are suspected to sporadically eject optically thick dust clouds causing, when one of them lies on the line-of-sight, a huge brightness decline in…
