Course description

.
Syllabus: This course studies star formation processes
starting from molecular clouds and going to pre-main sequence stars.
The main sections are cloud collapse and fragmentation, the ignition
of deuterium burning and fusion, outflows, shocks and ionization, and
the disrobing process
(the emergence of stars from clouds). Special topics
include the different routes of high and low mass star formation, the
development of disks and proto-planetary systems, and galactic-scale
phenomena. The emphasis is on observations, especially from the new
space-based observatories.
