Models of Rotating Infall for the B335 Protostar
Neal J. Evans, Yao-Lun Yang, Joel D. Green +7
Models of the protostellar source, B335, are developed using axisymmetric three-dimensional models to resolve conflicts found in one-dimensional models. The models are constrained…
FAUST III. Misaligned rotations of the envelope, outflow, and disks in the multiple protostellar system of VLA 16232417
Satoshi Ohashi, Claudio Codella, Nami Sakai +69
We report a study of the low-mass Class-0 multiple system VLA 1623AB in the Ophiuchus star-forming region, using HCO (), CS (), and CCH () lines as…
Accretion Flows or Outflow Cavities? Uncovering the Gas Dynamics around Lupus 3-MMS
Travis J. Thieme, Shih-Ping Lai, Sheng-Jun Lin +6
Understanding how material accretes onto the rotationally supported disk from the surrounding envelope of gas and dust in the youngest protostellar systems is important for describ…
No impact of core-scale magnetic field, turbulence, or velocity gradient on sizes of protostellar disks in Orion A
Hsi-Wei Yen, Bo Zhao, Patrick M. Koch +1
We compared the sizes and fluxes of a sample of protostellar disks in Orion A measured with the ALMA 0.87 mm continuum data from the VANDAM survey with the physical properties of t…
A protostellar system fed by a streamer of 10,500 au length
Jaime E. Pineda, Dominique Segura-Cox, Paola Caselli +5
Binary formation is an important aspect of star formation. One possible route for close-in binary formation is disk fragmentation. Recent observations show small scale…
Effect of grain size distribution and size-dependent grain heating on molecular abundances in starless and pre-stellar cores
O. Sipilä, B. Zhao, P. Caselli
We present a new gas-grain chemical model to constrain the effect of grain size distribution on molecular abundances in starless and pre-stellar cores. We introduce grain-size depe…
Rapid Elimination of Small Dust Grains in Molecular Clouds
Kedron Silsbee, Alexei Ivlev, Paola Caselli +2
We argue that impact velocities between dust grains with sizes less than in molecular cloud cores are dominated by drift arising from ambipolar diffusion. This effe…
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…
On the Effects of Self-Obscuration in the (Sub-)Millimeter Spectral Indices and Appearance of Protostellar Disks
Roberto Galván-Madrid, Hauyu Baobab Liu, Andrés F. Izquierdo +5
In this paper we explore the effects of self-obscuration in protostellar disks with a radially decreasing temperature gradient and a colder midplane. We are motivated by recent rep…
