Astronomy on Tap: Baby Planets (Leiden, in het Engels)

Op maandag 30 augustus vindt er voor het eerst in lange tijd weer een fysiek Astronomy on Tap in Leiden plaats. Het thema van de avond is Baby Planets. Sprekers zijn de sterrenkundigen Alice Booth en Pooneh Nazari. En natuurlijk zijn er weer ook leuke spelletjes waarmee prijzen gewonnen kunnen worden. Het evenement start om 20.00 uur in Grandcafé de Burcht. Aanmelden is gratis, maar wel verplicht vanwege de coronamaatregelen. De voertaal is Engels. Er is ook een livestream via YouTube.

Alice Booth: "Evaporating ices feeding forming planets"
Planets form in the disks of gas, dust and ice around young stars. Using the Atacama Large Millimeter Array we can now map the composition of the gas planets are accreting. One key question in astronomy is if complex organic molecules, the precursors of pre-biotic molecules responsible for life on Earth, are present in planet forming disks. These species have gone undetected in many young solar systems so far because they tend to be locked up in ices. Recent observations have revealed a rich reservoir of molecules in a disk due to ice sublimation. Thus, showing that complex molecules are present when planets are actively forming.

Pooneh Nazari: "What do baby planets eat?"
Pooneh is a PhD student in the astrochemistry group at the Leiden Observatory. Her work focuses on the chemistry in the environment around stars that are being born. Particularly, she is interested in looking at the stuff around young stars with large telescopes and finding clues on what goes into baby planets. In her talk, she will tell us about this phase of stars, and in particular about the baby planets around such stars and their diet.
