Now\, for a definite registration\, please check your doodle-entry and edit/add if necessary: http://doodle.com/poll/vksby8fhihss2gts \nAbstract:\nCombining photometric transits with radial velocity measurements yields planetary radius\, mass and thus bulk density. The possible range of interior structures that can be modelled from mass and radius is generally large. Also\, to date only few dozen of low-mass exoplanets (Mini-Neptunes and super-Earth) have uncertainties on mass and radius below 20 %. As a consequence\, the diversity among super-Earths and Mini-Neptunes is largely unknown. In the context of photometric experiments like NGTS\, TESS and CHEOPS and incoming RV facilities like ESPRESSO and NIRPS\, the workshop aims to adress the following main topics: \n– Precision and accuracy of planetary mass & radius measurements:\nPossible improvements and the importance of stellar parameters. \n– Characterization of planet interiors:\nQuantifying parameter degeneracy and the required data precision for determining interior types. \n– Planet formation and evolution:\nWhat we can learn from the distribution of exoplanets. \nPlace: Bern\, Uni Bern\, main building\, room 304\, Hochschulstrasse 6\, 3012 Bern \nConfirmed speakers and their topics are:\n Jose Almenara (UniGe) on photo-dynamical analysis of TTVs to derive precise densities\nFatemeh Motalebi (UniGe) on spectroscopic and photometric observations with HARPS-N\nJonas Haldemann (UniBe) on data precision that is needed to determine planetary interiors\nChristoph Mordasini (UniBe) on the transition from gaseous to solid planets \nIf you are interested in contributing a short presentation\, or suggesting a topic to be discussed\, please send an email to caroline.dorn@space.unibe.ch or Francois.Bouchy@unige.ch by end of March. \nLunch/snacks/coffee will be provided and travel expenses will be reimbursed by PlanetS. \nRegarding the expenses:\n– each institute pays for the travel of participants locally first and then sends a collective bill to the Academic Platform\n– the Academic Platform pays for the travel\, but not for overnight stays for 1-day workshops\nYou’ll soon receive the final schedule for the workshop day.\nBest wishes\,\nCaroline and François \n URL:https://nccr-planets.ch/event/workshop-exoplanet-densities-observations-modeling/ LOCATION:University of Bern\, main building\, room 304\, Hochschulstrasse 6\, 3012 Bern\, Switzerland CATEGORIES:Internal,Workshop END:VEVENT END:VCALENDAR
