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…
Impact of Magnetic Braking on High-mass Close Binary Formation
Naoto Harada, Shingo Hirano, Masahiro N. Machida +1
Combining numerical simulations and analytical modeling, we investigate whether close binary systems form by the effect of magnetic braking. Using magnetohydrodynamics simulations,…
Supermassive Star Formation in Magnetized Atomic-Cooling Gas Clouds: Enhanced Accretion, Intermittent Fragmentation, and Continuous Mergers
Shingo Hirano, Masahiro N. Machida, Shantanu Basu
The origin of supermassive black holes (with ) in the early universe (redshift ) remains poorly understood. Gravitational collapse of a massive…
ALMA Observations toward the S-shaped Outflow and the Envelope around NGC1333 IRAS 4A2
Chen-Yu Chuang, Yusuke Aso, Naomi Hirano +2
We have analyzed the ALMA archival data of the SO ( and ), CO (), and CCH () lines from the class 0 protobinary system, NG…
Large-scale variation in reionization history caused by Baryon-dark matter streaming velocity
Hyunbae Park, Paul R. Shapiro, Kyungjin Ahn +2
At cosmic recombination, there was supersonic relative motion between baryons and dark matter, which originated from the baryonic acoustic oscillations in the early universe. This…
The Effect of Misalignment between Rotation Axis and Magnetic Field on Circumstellar Disk
Shingo Hirano, Yusuke Tsukamoto, Shantanu Basu +1
The formation of circumstellar disks is investigated using three-dimensional resistive magnetohydrodynamic simulations, in which the initial prestellar cloud has a misaligned rotat…
