Multi-epoch Direct Imaging and Time-Variable Scattered Light Morphology of the HD 163296 Protoplanetary Disk

Evan A. Rich, John P. Wisniewski, Thayne Currie +58

We present H-band polarized scattered light imagery and JHK high-contrast spectroscopy of the protoplanetary disk around HD 163296 observed with the HiCIAO and SCExAO/CHARIS instru…

ALMA Reveals a Misaligned Inner Gas Disk inside the Large Cavity of a Transitional Disk

Satoshi Mayama, Eiji Akiyama, Olja Panić +15

Pairs of azimuthal intensity decrements at near symmetric locations have been seen in a number of protoplanetary disks. They are most commonly interpreted as the two shadows cast b…

Orbital characterization of GJ1108A system, and comparison of dynamical mass with model-derived mass for resolved binaries

T. Mizuki, M. Kuzuhara, K. Mede +55

We report an orbital characterization of GJ1108Aab that is a low-mass binary system in pre-main-sequence phase. Via the combination of astrometry using adaptive optics and radial v…

High-contrast Polarimetry Observation of T Tau Circumstellar Environment

Yi Yang, Satoshi Mayama, Saeko S. Hayashi +52

We conducted high-contrast polarimetry observations of T Tau in the H-band, using the HiCIAO instrument mounted on the Subaru Telescope, revealing structures as near as 0.$\arcsec$…

Differences in the gas and dust distribution in the transitional disk of a sun-like young star, PDS 70

Zachary C. Long, Eiji Akiyama, Michael Sitko +22

We present ALMA 0.87 mm continuum, HCO+ J=4--3 emission line, and CO J=3--2 emission line data of the disk of material around the young, Sun-like star PDS 70. These data reveal the…

Subaru/HiCIAO imaging of LkH 330 - multi-band detection of the gap and spiral-like structures

Taichi Uyama, Jun Hashimoto, Takayuki Muto +56

We present - and -bands observations of the LkH 330 disk with a multi-band detection of the large gap and spiral-like structures. The morphology of the outer disk…
