A 1.3 mm SMA Survey of 29 Variable Young Stellar Objects
Hauyu Baobab Liu, Michael M. Dunham, Ilaria Pascucci +16
Young stellar objects (YSOs) may undergo periods of active accretion (outbursts), during which the protostellar accretion rate is temporarily enhanced by a few orders of magnitude.…
The circumestellar disk of the B0 protostar powering the HH 80-81 radio jet
J. M. Girart, R. Estalella, M. Fernández-López +6
We present subarcsecond angular resolution observations carried out with the Submillimeter Array (SMA) at 880 m centered at the B0-type protostar GGD27~MM1, the driving source o…
ALMA observations of dust polarization and molecular line emission from the Class 0 protostellar source Serpens SMM1
Charles L. H. Hull, Josep M. Girart, Łukasz Tychoniec +10
We present high angular resolution dust polarization and molecular line observations carried out with the Atacama Large Millimeter/submillimeter Array (ALMA) toward the Class 0 pro…
Molecular outflow launched beyond the disk edge
Felipe O. Alves, Josep M. Girart, Paola Caselli +5
One of the long-standing problems of star formation is the excess of angular momentum of the parent molecular cloud. In the classical picture, a fraction of angular momentum of the…
Unveiling the Role of the Magnetic Field at the Smallest Scales of Star Formation
Charles L. H. Hull, Philip Mocz, Blakesley Burkhart +7
We report ALMA observations of polarized dust emission from the protostellar source Ser-emb 8 at a linear resolution of 140 au. Assuming models of dust-grain alignment hold, the ob…
Magnetized converging flows towards the hot core in the intermediate/high-mass star-forming region NGC 6334 V
Carmen Juárez, Josep M. Girart, Manuel Zamora-Avilés +7
We present Submillimeter Array (SMA) observations at 345 GHz towards the intermediate/high-mass cluster-forming region NGC 6334 V. From the dust emission we spatially resolve three…
