Exploring the ecology of star formation

Feb 8, 2018 11:00 AM to Feb 8, 2018 12:00 PM at Building 8, Room 241

 Most stars (and thus most planets) are born in clusters where feedback from nearby high-mass stars will impact everything from the fragmentation of gas into stars to the formation and evolution of planets. Stellar feedback may stimulate star formation by inducing otherwise stable clouds of gas and dust to collapse or it may starve future star formation by blowing away the rest of the natal cloud. Whether feedback helps or hinders star and planet formation remains debated. Ecological studies that root the formation of stars and planets in their typical birth environment are therefore essential to address the role of feedback in regulating star formation. In this talk, I will focus on one proto-typical high-mass star forming region to address three pieces of this puzzle: (1) how high-mass stars - the dominate source of the feedback - form; (2) how feedback from those stars affects the natal gas of the next generation; and (3) how feedback affects the birthplace of planets in the circumstellar disks around those stars.
