Coordinated X-ray and Optical observations of Star-Planet Interaction in HD 17156
A. Maggio, I. Pillitteri, G. Scandariato +14
The large number of close-in Jupiter-size exoplanets prompts the question whether star-planet interaction (SPI) effects can be detected. We focused our attention on the system HD 1…
Global Architecture of Planetary Systems (GAPS), a project for the whole Italian Community
Ennio Poretti, Caterina Boccato, Riccardo Claudi +13
The GAPS project is running since 2012 with the goal to optimize the science return of the HARPS-N instrument mounted at Telescopio Nazionale Galileo. A large number of astronomers…
CSI 2264: Accretion process in classical T Tauri stars in the young cluster NGC 2264
Alana Sousa, Silvia Alencar, Jérôme Bouvier +12
Our goal is to relate the photometric and spectroscopic variability of classical T Tauri stars, of the star-forming cluster NGC 2264, to the physical processes acting in the stella…
The GAPS Programme with HARPS-N@TNG IX. The multi-planet system KELT-6: detection of the planet KELT-6 c and measurement of the Rossiter-McLaughlin effect for KELT-6 b
M. Damasso, M. Esposito, V. Nascimbeni +39
Aims. For more than 1.5 years we monitored spectroscopically the star KELT-6 (BD+312447), known to host the transiting hot Saturn KELT-6b, because a previously observed long-term t…
The HARPS-N Rocky Planet Search I. HD219134b: A transiting rocky planet in a multi-planet system at 6.5 pc from the Sun
F. Motalebi, S. Udry, M. Gillon +36
We present here the detection of a system of four low-mass planets around the bright (V=5.5) and close-by (6.5 pc) star HD219134. This is the first result of the Rocky Planet Searc…
UV variability and accretion dynamics in the young open cluster NGC 2264
Laura Venuti, Jerome Bouvier, Jonathan Irwin +8
We explore UV and optical variability signatures for several hundred members of NGC 2264 (3 Myr). We performed simultaneous u- and r-band monitoring over two full weeks with CFHT/M…
