Abstract: Star formation is ubiquitous in the Galaxy, but the physical and
chemical conditions in star-forming sites might differ due to the
environment. For example, due to the negative metallicity gradient,
abundances of molecules and dust are expected to decrease with the
distance from the Galactic Center, and subsequently influence the
cooling budget and the star formation efficiency. Magnetic fields
(B-fields) are also believed to play an important role in star
formation processes and in the evolution of the molecular cloud.
In this talk I will present results in investigating the role of
metallicity and B-fields in molecular clouds where new stars are born
in our Galaxy. I will present results of infrared studies where we
characterized the gas accretion onto young stellar objects and the gas
cooling in embedded cluster in the Canis Major region at l~224°
(CMa-l224) in the outer Galaxy, using data from NASA/IRTF and
SOFIA/FIFI-LS, respectively. I will also present results concerning
roles of B-fields and stellar radiation from a nearby high-mass star
in regulating the star formation and shaping the nearby molecular
cloud Rho Ophiuchus-A.
