The Formation of Stars -- From Filaments to Cores to Protostars and Protoplanetry Disks
James Di Francesco, Helen Kirk, Doug Johnstone +16
Star formation involves the flow of gas and dust within molecular clouds into protostars and young stellar objects (YSOs) due to gravity. Along the way, these flows are shaped sign…
Investigating the Complex Velocity Structures within Dense Molecular Cloud Cores with GBT-Argus
Che-Yu Chen, Shaye Storm, Zhi-Yun Li +12
We present the first results of high-spectral resolution (0.023 km/s) NH observations of dense gas dynamics at core scales (~0.01 pc) using the recently commissioned Argus…
KFPA Examinations of Young STellar Object Natal Environments (KEYSTONE): Hierarchical Ammonia Structures in Galactic Giant Molecular Clouds
Jared Keown, James Di Francesco, Erik Rosolowsky +23
We present initial results from the K-band focal plane array Examinations of Young STellar Object Natal Environments (KEYSTONE) survey, a large project on the 100-m Green Bank Tele…
Droplets II: Internal Velocity Structures and Potential Rotational Motions in Pressure-dominated Coherent Structures
Hope How-Huan Chen, Jaime E. Pineda, Stella S. R. Offner +6
We present an analysis of the internal velocity structures of the newly identified sub-0.1 pc coherent structures, droplets, in L1688 and B18. By fitting 2D linear velocity fields…
Confirmation of Enhanced Long Wavelength Dust Emission in OMC 2/3
Brian Mason, Simon Dicker, Sarah Sadavoy +8
Previous continuum observations from the MUSTANG camera on the Green Bank Telescope (GBT) of the nearby star-forming filament OMC 2/3 found elevated emission at 3.3 mm relative to…
The JCMT BISTRO Survey: The Magnetic Field of the Barnard 1 Star-Forming Region
Simon Coudé, Pierre Bastien, Martin Houde +118
We present the POL-2 850 m linear polarization map of the Barnard 1 clump in the Perseus molecular cloud complex from the B-fields In STar-forming Region Observations (BISTRO) s…
The Green Bank Ammonia Survey: A Virial Analysis of Gould Belt Clouds in Data Release 1
Ronan Kerr, Helen Kirk, James Di Francesco +14
We perform a virial analysis of starless dense cores in three nearby star-forming regions : L1688 in Ophiuchus, NGC 1333 in Perseus, and B18 in Taurus. Our analysis takes advantage…
Efficient methanol production on the dark side of a prestellar core
Jorma Harju, Jaime E. Pineda, Anton I. Vasyunin +23
We present ALMA maps of the starless molecular cloud core Ophiuchus/H-MM1 in the lines of deuterated ammonia (ortho-NH2D), methanol (CH3OH), and sulphur monoxide (SO). The dense co…
The JCMT BISTRO Survey: The Magnetic Field In The Starless Core Ophiuchus C
Junhao Liu, Keping Qiu, David Berry +128
We report 850~m dust polarization observations of a low-mass (12 ) starless core in the Ophiuchus cloud, Ophiuchus C, made with the POL-2 instrument on the…
The central 1000 AU of a pre-stellar core revealed with ALMA. I. 1.3 mm continuum observations
Paola Caselli, Jaime E. Pineda, Bo Zhao +8
Stars like our Sun form in self-gravitating dense and cold structures within interstellar clouds, called pre-stellar cores. Although much is known about the physical structure of d…
Magnetic Field Structure of Dense Cores using Spectroscopic Methods
Sayantan Auddy, Philip C. Myers, Shantanu Basu +3
We develop a new ''core field structure'' (CFS) model to predict the magnetic field strength and magnetic field fluctuation profile of dense cores using gas kinematics. We use spat…
