Star Formation in Crowds

Star formation changes with the environment and high mass stars define the neighborhood


Star formation is the defining process in the evolution of galaxies.

Our present understanding of star formation has primarily been informed by low-mass

stars in nearby clouds, but these nearby regions do not reflect typical

conditions over the history of the universe. The denser and more crowded

regions that likely represent our own origins exist within our own Galaxy, and

ALMA allows us to explore these regions in ways previously impossible. I will

show that high-density regions lead to the preferential formation of clusters over

isolated stars. n these dense, clustered regions, the stellar initial mass

function (IMF) is governed, and perhaps changed, by feedback from high-mass

stars. With the new ability to identify individual protostars in distant

regions, we can now directly measure how many stars are forming and determine

how the prerequisites for gas to collapse into stars change with the environment.

Finally, I will describe the recently-begun ALMA-IMF large program that will

expand these studies to a Galactic scale.
