Complex organic molecules with three carbon atoms are found in the earliest stages of star formation. In particular, propenal (CHCHO) is a species of interest due to its im…
Constraining the Infalling Envelope Models of Embedded Protostars: BHR 71 and its Hot Corino
Y. -L. Yang, N. J. Evans, A. Smith +7
The collapse of the protostellar envelope results in the growth of the protostar and the development of a protoplanetary disk, playing a critical role during the early stages of st…
Understanding the origin of the magnetic field morphology in the wide-binary protostellar system BHR 71

We present 1.3 mm ALMA observations of polarized dust emission toward the wide-binary protostellar system BHR 71 IRS1 and IRS2. IRS1 features what appears to be a natal, hourglass-…
The Mass Evolution of Protostellar Disks and Envelopes in the Perseus Molecular Cloud
Bridget C. Andersen, Ian W. Stephens, Michael M. Dunham +8
In the standard picture for low-mass star formation, a dense molecular cloud undergoes gravitational collapse to form a protostellar system consisting of a new central star, a circ…
