Direct Imaging Explorations for Companions from the Subaru/IRD Strategic Program II; Discovery of a Brown-dwarf Companion around a Nearby mid-M~dwarf LSPM~J1446+4633
Taichi Uyama, Masayuki Kuzuhara, Charles Beichman +35
We report the discovery of a new directly-imaged brown dwarf companion with Keck/NIRC2+pyWFS around a nearby mid-type M~dwarf LSPM~J1446+4633 (hereafter J1446). The -band contr…
Anisotropic Ionizing Illumination from an M-type Pre-main Sequence Star, DM Tau
Yuka Terada, Hauyu Baobab Liu, David Mkrtichian +6
The powerful, high-energy magnetic activities of young stars play important roles in the magnetohydrodynamics in the innermost parts of the protoplanetary disks. In addition, the a…
Direct Imaging Explorations for Companions around Mid-Late M Stars from the Subaru/IRD Strategic Program
Taichi Uyama, Charles Beichman, Masayuki Kuzuhara +32
The Subaru telescope is currently performing a strategic program (SSP) using the high-precision near-infrared (NIR) spectrometer IRD to search for exoplanets around nearby mid/late…
Infrared Spectroscopy of free-floating planet candidates in Upper Scorpius and Ophiuchus
H. Bouy, M. Tamura, D. Barrado +15
Context: A rich population of low-mass brown dwarfs and isolated planetary mass objects has been reported recently in the Upper Scorpius and Ophiuchus star forming complex. Aims: W…
GW Ori: Interactions Between a Triple-star System and its Circumtriple Disk in Action
Jiaqing Bi, Nienke van der Marel, Ruobing Dong +17
GW Ori is a hierarchical triple system which has a rare circumtriple disk. We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of 1.3 mm dust continuum and…
The Matryoshka Disk: Keck/NIRC2 Discovery of a Solar System-Scale, Radially Segregated Residual Protoplanetary Disk Around HD 141569A
Thayne Currie, Carol Grady, Ryan Cloutier +7
Using Keck/NIRC2 (3.78 ) data, we report the direct imaging discovery of a scattered light-resolved, solar system-scale residual protoplanetary disk around the young…
