Characterizing Planetary Systems Across the HR Diagram

Characterizing Planetary Systems Across the HR Diagram

The University of Cambridge Institute of Astronomy will host a 5 day scientific meeting to further our understanding of the formation and evolution of planetary systems. The meeting will focus on the full lifetime of planetary systems, from pre- to post-main sequence host star stages, and the connections that can be made by viewing these…

The outer regions of extrasolar planetary systems

The outer regions of extrasolar planetary systems

Over the past two decades we learned that extrasolar planets are common in the Galaxy and that they exhibit an astonishing diversity in all accessible parameters. Planets that orbit close to their host star, i.e. at orbital distances of less than 1 AU, are easier to access observationally, thus represent the bulk of the exoplanet…

Gliese 832c, una super-Terra vicina potenzialmente abitabile

Un gruppo internazionale di astronomi guidati da Robert A. Wittenmyer della University of New South Wales (UNSW) in Sydney, Australia riportano la scoperta di una nuova super-Terra potenzialmente abitabile nel sistema stellare Gliese 832, una nana rossa nella costellazione della Gru che si trova relativamente vicina, 16 anni-luce. La stella è già nota perchè ospita un oggetto gioviano…
