The young protostellar disk in IRAS16293-2422 B is hot and shows signatures of gravitational instability
Joaquin Zamponi, María José Maureira, Bo Zhao +4
Deeply embedded protostars are actively fed from their surrounding envelopes through their protostellar disk. The physical structure of such early disks might be different from tha…
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…
FAUST II. Discovery of a Secondary Outflow in IRAS 15398-3359: Variability in Outflow Direction during the Earliest Stage of Star Formation?
Yuki Okoda, Yoko Oya, Logan Francis +66
We have observed the very low-mass Class 0 protostar IRAS 15398-3359 at scales ranging from 50 au to 1800 au, as part of the ALMA Large Program FAUST. We uncover a linear feature,…
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…
