Observationally derived magnetic field strength and 3D components in the HD 142527 disk
Satoshi Ohashi, Takayuki Muto, Yusuke Tsukamoto +5
In protoplanetary disks around young stars, magnetic fields play an important role for disk evolution and planet formation. Polarized thermal emission from magnetically aligned gra…
Chemistry of Complex Organic Molecules in the V883 Ori Disk Revealed by ALMA Band 3 Observations
Yoshihide Yamato, Shota Notsu, Yuri Aikawa +3
Complex organic molecules (COMs) in protoplanetary disks are key to understanding the origin of volatiles in comets in our solar system, yet the chemistry of COMs in protoplanetary…
Dust enrichment and grain growth in a smooth disk around the DG Tau protostar revealed by ALMA triple bands frequency observations
Satoshi Ohashi, Munetake Momose, Akimasa Kataoka +10
Characterizing the physical properties of dust grains in a protoplanetary disk is critical to comprehending the planet formation process. Our study presents ALMA high-resolution ob…
Formation of dust clumps with sub-Jupiter mass and cold shadowed region in gravitationally unstable disk around Class 0/I protostar in L1527 IRS
Satoshi Ohashi, Riouhei Nakatani, Hauyu Baobab Liu +4
We have investigated the protostellar disk around a Class 0/I protostar, L1527 IRS, using multi-wavelength observations of the dust continuum emission at , 2.1, 3.3, and 6.…
No evidence of the significant grain growth but tentative discovery of disk substructure in a disk around the Class I Protostar L1489 IRS
Satoshi Ohashi, Hiroshi Kobayashi, Jinshi Sai +1
For revealing the first step of the plant formation, it is important to understand how and when dust grains become larger in a disk around a protostar. To investigate the grain gro…
Ring formation by coagulation of dust aggregates in early phase of disk evolution around a protostar
Satoshi Ohashi, Hiroshi Kobayashi, Riouhei Nakatani +6
Ring structures are observed by (sub-)millimeter dust continuum emission in various circumstellar disks from early stages of Class 0 and I to late stage of Class II young stellar o…
