Planetary System Formation in Protoplanetary Disk around HL Tauri
Eiji Akiyama, Yasuhiro Hasegawa, Masahiko Hayashi +1
We re-process the Atacama Large Millimeter/Submillimeter Array (ALMA) long-baseline science verification data taken toward HL Tauri. As shown by the previous work, we confirm that…
Development of a Method for the Observation of Lightning in Protoplanetary Disks Using Ion Lines
Takayuki Muranushi, Eiji Akiyama, Shu-ichiro Inutsuka +2
In this paper, we propose observational methods for detecting lightning in protoplanetary disks. We do so by calculating the critical electric field strength in the lightning matri…
Significant Gas-to-Dust Ratio Asymmetry and Variation in the Disk of HD 142527 and the Indication of Gas Depletion
Takayuki Muto, Takashi Tsukagoshi, Munetake Momose +14
We investigate the dust and gas distribution in the disk around HD 142527 based on ALMA observations of dust continuum, 13CO(3-2), and C18O(3-2) emission. The disk shows strong azi…
Near-IR Polarized Scattered Light Imagery of the DoAr 28 Transitional Disk
Evan A. Rich, John P. Wisniewski, Satoshi Mayama +52
We present the first spatially resolved polarized scattered light H-band detection of the DoAr 28 transitional disk. Our two epochs of imagery detect the scattered light disk from…
Detailed structure of the outer disk around HD 169142 with polarized light in H-band
Munetake Momose, Ayaka Morita, Misato Fukagawa +59
Coronagraphic imagery of the circumstellar disk around HD 169142 in H-band polarized intensity (PI) with Subaru/HiCIAO is presented. The emission scattered by dust particles at the…
Near-IR High-Resolution Imaging Polarimetry of the SU Aur Disk: Clues for Tidal Tails?
Jerome de Leon, Michihiro Takami, Jennifer L. Karr +53
We present new high-resolution (0\farcs09) -band imaging observations of the circumstellar disk around the T Tauri star SU Aur. Our observations with Subaru-HiCIAO have re…
