An image of the dust sublimation region in the nucleus of NGC 1068
GRAVITY Collaboration, O. Pfuhl, R. Davies +40
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…
Gas flow and accretion via spiral streamers and circumstellar disks in a young binary protostar
Felipe O. Alves, Paola Caselli, Josep M. Girart +4
The majority of stars are part of gravitationally bound stellar systems, such as binaries. Observations of protobinary systems constrain the conditions that lead to stellar multipl…
The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars I. Identifying and Characterizing the Protostellar Content of the OMC2-FIR4 and OMC2-FIR3 Regions
John J. Tobin, S. Thomas Megeath, Merel van 't Hoff +31
We present ALMA (0.87~mm) and VLA (9~mm) observations toward OMC2-FIR4 and OMC2-FIR3 within the Orion integral-shaped filament that are thought to be the nearest regions of interme…
Dust Polarization Toward Embedded Protostars in Ophiuchus with ALMA. III. Survey Overview
Sarah I. Sadavoy, Ian W. Stephens, Philip C. Myers +7
We present 0.25 arcsec resolution (35 au) ALMA 1.3 mm dust polarization observations for 37 young stellar objects (YSOs) in the Ophiuchus cloud. These data encompass all the embedd…
The specific angular momentum radial profile in dense cores: improved initial conditions for disk formation
Jaime E. Pineda, Bo Zhao, Anika Schmiedeke +5
The determination of the specific angular momentum radial profile, , in the early stages of star formation is crucial to constrain star and circumstellar disk formation theor…
Polarization in Disks
Ian Stephens, Zhi-Yun Li, Haifeng Yang +24
Polarized dust emission outside of disks reveal the magnetic field morphology of molecular clouds. Within disks, however, polarized dust emission can arise from very different mech…
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…
