APEX this week: Planet formation with ALMA and JWST
This week at APEX we are delighted to welcome Dr Sebastiaan Krijt, a Senior Lecturer in Astrophysics at the University of Exeter. This will be a hybrid event, held at UCL and online.
APEX this week: Planet formation with ALMA and JWST
21 Mar 2025, 13:00 – 14:00
Our final Astrobiology and Planetary Exploration (APEX) seminar this term takes place on Friday 21st March at 13:00 GMT and features the following talk:
- Sebastiaan Krijt (Exeter): Planet formation with ALMA & JWST: Signatures of past and ongoing pebble migration in protoplanetary discs
An abstract for Sebastiaan’s talk can be found below.
Please note the day and location for APEX this term: Fridays at lunchtime, 1-2 pm GMT, in the G22 Lecture Theatre on the ground floor of the UCL North West Wing building.
A hybrid (in-person and online) format will continue this term but, of course, we warmly encourage in-person attendance to support our visiting speakers.
We have a special APEX seminar on Friday 25th April with Dr Jan Špaček from the ALFA Mars project. Details can be found on the current programme. Otherwise, we resume the series next academic year in October 2025.
If you are not on our regular mailing lists and are interested in attending these seminars, please contact joanna.fabbri AT ucl.ac.uk.
Talk abstract
Planet formation with ALMA & JWST: Signatures of past and ongoing pebble migration in protoplanetary discs
The properties of planetary systems depend sensitively on the physical and chemical structure of the protoplanetary discs in which they form. At the same time, the processes associated with planet formation can dramatically influence the evolution of protoplanetary discs. In this talk, I will focus on the ways in which planet formation via core accretion can shape the chemical environment of growing protoplanets. In particular, I will discuss the consequences of dust coagulation, pebble drift, planetesimal formation and pebble accretion on gas-phase molecular and elemental abundances, highlighting exciting ongoing efforts to study for the signatures of these processes with ALMA and JWST.

APEX Seminars
The Astrobiology and Planetary Exploration (APEX) seminar series takes place this term on Friday lunchtimes, from 1-2pm, in the G22 Lecture Theatre of UCL’s North West Wing building in the Bloomsbury Campus. As in previous years, we will operate a hybrid (online and in-person) model for both speakers and attendees. Details of the forthcoming APEX programme can be found via the link below.
Some of our past APEX talks can also be viewed online.
