Astro2020 Science White Paper: Measuring Protostar Masses: The Key to Protostellar Evolution
John J. Tobin, Stella Offner, Patrick Sheehan +10
Knowledge of protostellar evolution has been revolutionized with the advent of surveys at near-infrared to submillimeter wavelengths. This has enabled the bolometric luminosities a…
Astro2020 Science White Paper: The Formation and Evolution of Multiple Star Systems
John J. Tobin, Marina Kounkel, Stella Offner +13
Significant advances have been made over the past decade in the characterization of multiple protostar systems, enabled by the Karl G. Jansky Very Large Array (VLA), high-resolutio…
The fastest components in stellar jets
Hans Moritz Günther, Catherine Espaillat, Kevin France +8
Young stars accrete mass from a circumstellar disk, but at the same time disk and star eject outflows and jets. These outflows have an onion-like structure where the innermost and…
Low Mass Stars as Tracers of Star Formation in Diverse Environments
S. Thomas Megeath, Marina Kounkel, Stella Offner +8
Background: low-mass stars are the dominant product of the star formation process, and they trace star formation over the full range of environments, from isolated globules to clus…
Variability in the Assembly of Protostellar Systems
Joel D. Green, Yao-Lun Yang, Tom Megeath +17
Understanding the collapse of clouds and the formation of protoplanetary disks is essential to understanding the formation of stars and planets. Infall and accretion, the mass-aggr…
