High-Mass star formation triggered by frequent cloud-cloud collisions
For over four decades it has been debated whether external triggering
can substantially enchance starformation. One highly plausible
candidate si the influence from high-mass stars, via their UV
radiation, winds and supernova explosion. However, recent work has
suggested that collisions between molecular clouds may play a
previously underestimated role in tiggering high-mass star formation. I
will present new milecular observations of high-mass star forming
regions including yound super star cluster and Spitzer Bubbles and
discuss that high-mass star formation has been tiggered by cloud-cloud
collisons at a relative velocity of 10-20 km s-1. Such collisons are
taking place once every 100 yrs in the Galaxy and may be one to the
dominat modes of high-mass star formation. November 29, 2012
