Lunch talk

This is a talk given at lunch time, usually in the conference room at noon.


Friday, January 22, 2021 - 2:00pm to 3:00pm
Jorge Zavala (University of Texas)

Probing interstellar medium and galaxy evolution with infrared emission lines

Friday, October 16, 2020 - 2:00pm to 3:00pm
Shengqi Yang (NYU)

Far-infrared (FIR) and submillimeter (submm) lines emitted from the interstellar medium (ISM) not only reflect the ISM physical properties that are correlated with the star formation (SF) process, but also trace the underlying density distribution and promise cosmological studies.

The Core-Collapse Supernova Critical Condition and the Birth of Millisecond Proto-Magnetar Winds

Friday, December 4, 2020 - 2:00pm to 3:00pm
Matthias Raives (OSU)

The mechanism powering core-collapse supernovae remains uncertain. I will discuss aspects of the critical condition for explosion, focusing on the model problem of spherical accretion onto a standing accretion shock.

The high-energy environment and atmospheric escape of small exoplanets

Friday, October 2, 2020 - 10:00am to 11:00am
Leonardo dos Santos (University of Geneva)

Similarly to stars, planets also lose mass with time, even our own Earth. In particular, hot extrasolar planets orbiting close to their host stars are subject to large mass loss rates due to heating by high-energy irradiation and subsequent atmospheric escape.
