Two massive rocky planets transiting a K-dwarf 6.5 parsecs away

Michael Gillon, Brice-Olivier Demory, Valerie Van Grootel +14

HD 219134 is a K-dwarf star at a distance of 6.5 parsecs around which several low-mass planets were recently discovered. The Spitzer space telescope detected a transit of the inner…

Gaia-ESO Survey: Gas dynamics in the Carina Nebula through optical emission lines

F. Damiani, R. Bonito, L. Magrini +28

We present observations from the Gaia-ESO Survey in the lines of H, [N II], [S II] and He I of nebular emission in the central part of the Carina Nebula. We investigate the prop…

Supersaturation and activity-rotation relation in PMS stars: the young Cluster h Per

C. Argiroffi, M. Caramazza, G. Micela +4

The magnetic activity of late-type MS stars is characterized by different regimes, and their activity levels are well described by Ro, the ratio between P_rot and the convective tu…

Using the transit of Venus to probe the upper planetary atmosphere

Fabio Reale, Angelo F. Gambino, Giuseppina Micela +3

The atmosphere of a transiting planet shields the stellar radiation providing us with a powerful method to estimate its size and density. In particular, because of their high ioniz…

Non-thermal processes in colliding-wind massive binaries: the contribution of Simbol-X to a multiwavelength investigation

M. De Becker, R. Blomme, G. Micela +5

Several colliding-wind massive binaries are known to be non-thermal emitters in the radio domain. This constitutes strong evidence for the fact that an efficient particle accelerat…

Simbol-X capability of detecting the non-thermal emission of stellar flares

C. Argiroffi, G. Micela, A. Maggio

We investigate the capability of detecting, with Simbol-X, non-thermal emission during stellar flares, and distinguishing it from hot thermal emission. We find that flare non-therm…
