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 evolutionary stages as parts of a whole. In this way, the program aims to provide an integrative approach rather than focusing on each stellar stage separately. Continua a leggere Characterizing Planetary Systems Across the HR Diagram

Beta Pictoris b, measured the rotation rate of the exoplanet

Observations from ESO’s Very Large Telescope (VLT) have, for the first time, determined the rotation rate of an exoplanet. Beta Pictoris b has been found to have a day that lasts only eight hours. This is much quicker than any planet in the Solar System, its equator is moving at almost 100.000 kilometres per hour. This new result extends the relation between mass and rotation seen in the Solar System to exoplanets. Similar techniques will allow astronomers to map exoplanets in detail in the future with the European Extremely Large Telescope (E-ELT).

IAU Symposium 299: Exploring the Formation and Evolution of Planetary Systems

This symposium will bring together experts on the growth of planetary systems in protoplanetary discs through their early evolution to the final systems we observe around main-sequence stars today. Our goal is to enhance the interaction between those who study the formation of planets and those who study evolved exoplanets—two communities who do not typically interact strongly due to differences in instrumentation. Bringing these two communities together will allow us to ask provocative new questions, stimulate new avenues of research, and encourage the formation of new collaborations. The timing of this meeting is chosen to highlight early high-resolution imaging of planetary systems in formation by the interferometers ALMA, EVLA, LBTI and PRIMA, and direct imaging of exoplanets by a new generation of instruments: GPI (Gemini), SPHERE (VLT), HiCIAO/SCExAO (Subaru), FLAO/LUCIFER (LBT). We encourage inclusion of results from current and future facilities. We also encourage theoretical efforts to understand these results and inspire further observations. The IAUS 299 is being organized by the National Research Council of Canada Herzberg Institute of Astrophysics and the Dunlap Institute for Astronomy & Astrophysics, University of Toronto. The organizers would like to acknowledge the sponsorship of the International Astronomical Union, the University of Victoria and the Gemini Observatory.
