Gas infall via accretion disk - late findings
Alberto Sanna INAF, Cagliari, IT | |
In this seminar, I will present novel, high-angular resolution observations of one of the closest, massive, young-stellar-objects to the Sun. For the first time, these observations reveal the details of how fast circumstellar gas collapses and slowly spins to pile up near a young star at high rates of 10-3 Msun/yr, within disk radii of only 700au and less. I will discuss both state-of-the-art simulations and a toy model which reproduce our observations in detail, commenting on (1) how these new findings advance our knowledge of (proto-)stellar disks at large and (2) how they can drive future observations in the field. | |
