“Assessing and understanding variations in the outcome of star formation”

ABSTRACT

Star formation is a multi-physics and multi-scale process whose outcome is likely to depend on the physical conditions prevailing in different galactic environments. Assessing the existence of such a dependence requires the use of large observational datasets while understanding its origin requires the development of theoretical models that can take into account the diverse physical conditions found across star forming regions in the Milky Way and in nearby galaxies.

I will discuss how several processes such as turbulent fragmentation, feedback from massive stars, and large scale gas+star instabilities can help explain the observed scatter in the star formation scaling relations in galactic disks. I will also discuss some of the observed cluster-to-cluster variations of the stellar initial mass function in our galaxy and in the Andromeda galaxy.

STUDENTS – after the talk, you’re encouraged to return to the 2nd floor Atrium lounge to meet with the speaker.

COFFEE – coffee and cookies will be available in the 2nd floor Atrium lounge at 1:15 p.m.

CELL PHONES – as a courtesy to the speaker and audience, please set your cellphones to “silent” mode. Thanks!
