A Hybrid Origin for the Multiple Ring-Gap Structures in the Large Protoplanetary Disk V1094 Sco: A Low-Mass Planet and Secular Gravitational Instability
Masayuki Yamaguchi, Masahiro N. Machida, Ryosuke T. Tominaga +7
High spatial resolution observations reveal that some protoplanetary disks host multiple ring-gap pairs at large stellocentric radii, yet their physical origin remains unsettled. W…
Nonthermal Velocity Dispersion in the Outer Disk of HL Tau
Jinshi Sai, Shigehisa Takakuwa, Hsi-Wei Yen +2
Turbulence in protoplanetary disks plays a crucial role in the evolution of disk structures and the planet formation process therein. However, the strength of the turbulence remain…
Morphological and Kinematical Diagnostic of FU Orionis-type Outburst Mechanisms
Jinshi Sai, Eduard I. Vorobyov, Alexandr Skliarevskii +1
We investigated the possibility of determining the mechanism of the FU Orionis-type outburst based on molecular line observations of protoplanetary disks with synthetic observation…
Early Planet Formation in Embedded Disks (eDisk) XXII: Keplerian disk, disk structures and jets/outflows in the Class 0 protostar IRAS 04166+2706
Nguyen Thi Phuong, Chang Won Lee, John J. Tobin +20
We present ALMA observations of the Class 0 protostar IRAS 04166+2706, obtained as part of the ALMA large program Early Planet Formation in Embedded Disks (eDisk). These observatio…
Early Planet Formation in Embedded Disks (eDisk) XVII: A Compact but Structured Keplerian Disk and Large-scale Streamers Revealed in the Class I Protostellar System IRAS 04169+2702
Ilseung Han, Woojin Kwon, Yusuke Aso +22
We present high-resolution (0.05"; 8 au) dust continuum and molecular line observations toward the Class I protostellar system IRAS 04169+2702 in the Taurus B213 region, as p…
Hints of Disk Substructure in the First Brown Dwarf with a Dynamical Mass Constraint
Alejandro SantamarÃa Miranda, Pietro Curone, Laura Pérez +14
We present high-resolution ALMA observations at 0.89 mm of the Class II brown dwarf 2MASS J04442713+2512164 (2M0444), achieving a spatial resolution of 0046 (…
