Time-variable Scattered Light in Herbig Disks Observed with Subaru/SCExAO
Camryn Mullin, Miles Lucas, Ruobing Dong +12
Using the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument, we present near-infrared K-band polarimetric imaging of nine Herbig stars selected from a volume-limited…
ALMA 873 m Polarization Observations of the PDS~70 Disk
Hauyu Baobab Liu, Kiyoaki Doi, Simon Casassus +4
At a 112.4 pc distance, the PDS70 protoplanetary disk is a rare case that has been confirmed to host two accreting planets. This makes it the most important laboratory for studying…
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…
Mapping the merging zone of late infall in the AB Aur planet-forming system
Jessica Speedie, Ruobing Dong, Richard Teague +10
Late infall events challenge the traditional view that planet formation occurs without external influence. Here we present deep ALMA CO and SO observ…
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…
