The Interplay between Ambipolar Diffusion and Hall Effect on Magnetic Field Decoupling and Protostellar Disc Formation
Bo Zhao, Paola Caselli, Zhi-Yun Li +3
Non-ideal MHD effects have been shown recently as a robust mechanism of averting the magnetic braking "catastrophe" and promoting protostellar disc formation. However, the magnetic…
Hall Effect in Protostellar Disc Formation and Evolution
Bo Zhao, Paola Caselli, Zhi-Yun Li +3
The Hall effect is recently shown to be efficient in magnetized dense molecular cores, and could lead to a bimodal formation of rotationally supported discs (RSDs) in the first cor…
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…
Formation and Evolution of Disks around Young Stellar Objects
Bo Zhao, Kengo Tomida, Patrick Hennebelle +9
Recent observations have suggested that circumstellar disks may commonly form around young stellar objects. Although the formation of circumstellar disks can be a natural result of…
Transition from ordered pinched to warped magnetic field on a 100 au scale in the Class 0 protostar B335
Hsi-Wei Yen, Bo Zhao, Patrick Koch +6
We present our observational results of the 0.87 mm polarized dust emission in the Class 0 protostar B335 obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) at a…
Impact of magneto-rotational instability on grain growth in protoplanetary disks: I. Relevant turbulence properties
Munan Gong, Alexei V. Ivlev, Bo Zhao +1
Turbulence in the protoplanetary disks induces collisions between dust grains, and thus facilitates grain growth. We investigate the two fundamental assumptions of the turbulence i…
