Asymmetric dust accumulation of the PDS 70 disk revealed by ALMA Band 3 observations
Kiyoaki Doi, Akimasa Kataoka, Hauyu Baobab Liu +5
The PDS 70 system, hosting two planets within its disk, is an ideal target for examining the effect of planets on dust accumulation, growth, and ongoing planet formation. Here, we…
Detection of Dimethyl Ether in the Central Region of the MWC 480 Protoplanetary Disk
Yoshihide Yamato, Yuri Aikawa, Viviana V. Guzmán +9
Characterizing the chemistry of complex organic molecules (COMs) at the epoch of planet formation provides insights into the chemical evolution of the interstellar medium (ISM) and…
Early Planet Formation in Embedded Disks (eDisk) XIV: Flared Dust Distribution and Viscous Accretion Heating of the Disk around R CrA IRS 7B-a
Shigehisa Takakuwa, Kazuya Saigo, Miyu Kido +22
We performed radiative transfer calculations and observing simulations to reproduce the 1.3-mm dust-continuum and CO (2-1) images in the Class I protostar R CrA IRS7B-a, obs…
Early Planet Formation in Embedded Disks (eDisk) XII: Accretion streamers, protoplanetary disk, and outflow in the Class I source Oph IRS63
Christian Flores, Nagayoshi Ohashi, John J. Tobin +25
We present ALMA observations of the Class I source Oph IRS63 in the context of the Early Planet Formation in Embedded Disks (eDisk) large program. Our ALMA observations of Oph IRS6…
Early Planet Formation in Embedded Disks (eDisk). VIII. A Small Protostellar Disk around the Extremely Low-Mass and Young Class 0 Protostar, IRAS 15398-3359
Travis J. Thieme, Shih-Ping Lai, Nagayoshi Ohashi +22
Protostellar disks are a ubiquitous part of the star formation process and the future sites of planet formation. As part of the Early Planet Formation in Embedded Disks (eDisk) lar…
