This week’s (14th Oct) virtual Wednesday talk will be by Carlo Manara (ESO), who will present “Protoplanetary disk evolution and planet formation across time and space”
Members of the School can access this seminar via Microsoft Teams
ABSTRACT: In the last years we have expande our understanding of when, where, and how planets form. In particular, we are starting to constrain the timescale on which planets form, and to have a better understanding of the properties of their natal disks. Whether these properties of protoplanetary disks are similar in different stellar environments is still matter of debate. The mechanisms driving disk evolution, which are tested by combining spectroscopic and millimetre observations of disks and their stars, can be different in more massive clusters with respect to the nearby low-mass star-forming regions.
I will report on our extensive surveys in several star-forming regions from the nearby Lupus and Chamaeleon I regions, to the further away sigma Orionis and lambda Orionis cluster, carried out with VLT/X-Shooter spectroscopy and with high-resolution ALMA sub-mm data to show what we have learned on how protoplanetary disks evolve.
