X-ray activity phased with planet motion in HD 189733?
I. Pillitteri, H. M. Guenther, S. J. Wolk +2
We report on the follow-up XMM-Newton observation of the planet-hosting star HD 189733 we obtained in April 2011. We observe a flare just after the secondary transit of the hot Jup…
Starspots on the fastest rotators in the Beta Pic moving group
D. Garcia-Alvarez, A. F. Lanza, S. Messina +7
Aims: We carried out high-resolution spectroscopy and BV(I)_C photometric monitoring of the two fastest late-type rotators in the nearby Beta Pictoris moving group, HD199143 (F7V)…
The Dynamics of Stellar Coronae Harboring Hot-jupiters II. A Space Weather Event on A Hot-jupiter
O. Cohen, V. L. Kashyap, J. J. Drake +2
We carry out a numerical simulation depicting the effects of a Coronal Mass Ejection (CME) event on a close-in giant planet in an extrasolar system. We drive the CME in a similar m…
