The Birth of the Planets

Planet Hunters

by Prof Tom Ray (DIAS)

Monday, 26th April 2021 (at 19:30 Irish Summer Time).
Venue: online zoom.

You can join the meeting a few minutes before the event by clicking on this Zoom link.

With the recent discovery of vast numbers of exoplanets and new facilities such as the Atacama Millimetre Array (ALMA) our ideas of how planets form have changed radically in the past decade. In this talk, Prof. Tom Ray will describe some of these new findings and also look forward to what the near-future might reveal with the launch of the James Webb Space Telescope and the building of the Extremely Large Telescope in Chile.

Tom Ray is a Senior Professor at the Dublin Institute of Advanced Studies. His main research interests are in star and planet formation.
