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…
ALMA 2D super-resolution imaging survey of Ophiuchus Class I/flat spectrum/II disks. II. Statistical analysis of stellar and disk properties
Ayumu Shoshi, Masayuki Yamaguchi, Takayuki Muto +5
We present a statistical study of stellar and dust disk properties for young stellar objects in the Ophiuchus star-forming region. Building on our previous paper (Shoshi et al. 202…
VLT/MUSE Detection of the AB Aurigae b Protoplanet with Spectroscopy
Thayne Currie, Jun Hashimoto, Yuhiko Aoyama +6
We analyze high-contrast, medium-spectral-resolution observations of the star AB Aurigae using the Very Large Telescope's Multi Unit Spectroscopic Explorer (MUSE). In…
JVLA Measurement of Grain Size in the Compact Dust Ring around Class I Protostar WL 17
Jun Hashimoto, Hauyu Baobab Liu, Ruobing Dong +2
The maximum grain size in protoplanetary disks is a critical parameter for planet formation, as the efficiency of mechanisms like streaming instability and pebble accretion depend…
Predictions of Dust Continuum Emission from a Potential Circumplanetary Disk: A Case Study of the Planet Candidate AB Aurigae b
Yuhito Shibaike, Jun Hashimoto, Ruobing Dong +3
Gas accreting planets embedded in protoplanetary disks are expected to show dust thermal emission from their circumplanetary disks (CPDs). However, a recently reported gas accretin…
First JVLA Radio Observation on PDS70
Hauyu Baobab Liu, Simon Casassus, Ruobing Dong +3
PDS~70 is a protoplanetary system that hosts two actively accreting gas giants, namely PDS~70b and PDS~70c. The system has a 60--100 au dusty ring that has been resolved by A…
