A Comparative Analysis of Streamers and their Properties in the Youngest Protostars
Presenter: Travis Thieme (ASIAA)
Streamers are commonly observed around the youngest protostars and their properties are important for understanding the dynamical environments in which protostellar disks are formed. We present a comparative analysis of streamers identified around protostars in the Early Planet Formation in Embedded Disks (eDisk) large program. We consistently model our sample of streamers using infalling, parabolic trajectories under the assumptions of the gravitational collapse of a rotating, spherically symmetric protostellar core. We use our modeling results to investigate several important questions about streamers: 1) Can our streamline model consistently match with a large sample of streamers?, 2) How does the choice of parameters influence our streamline modeling?, 3) Are streamers common around protostellar disks in the earliest stages of star formation?, and 4) How do the properties of streamers compare and evolve over time?
