A belt-like distribution of gaseous hydrogen cyanide on Neptune's equatorial stratosphere detected by ALMA
Takahiro Iino, Hideo Sagawa, Takashi Tsukagoshi +1
We present a spatially resolved map of integrated-intensity and abundance of Neptune's stratospheric hydrogen cyanide (HCN). The analyzed data were obtained from the archived 2016…
TW Hya: an old protoplanetary disc revived by its planet
Sergei Nayakshin, Takashi Tsukagoshi, Cassandra Hall +6
Dark rings with bright rims are the indirect signposts of planets embedded in protoplanetary discs. In a recent first, an azimuthally elongated AU-scale blob, possibly a planet, wa…
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…
Super-resolution Imaging of the Protoplanetary Disk HD 142527 Using Sparse Modeling
Masayuki Yamaguchi, Kazunori Akiyama, Takashi Tsukagoshi +7
With an emphasis on improving the fidelity even in super-resolution regimes, new imaging techniques have been intensively developed over the last several years, which may provide s…
Scattering-induced intensity reduction: large mass content with small grains in the inner region of the TW Hya disk
Takahiro Ueda, Akimasa Kataoka, Takashi Tsukagoshi
Dust continuum observation is one of the best methods to constrain the properties of protoplanetary disks. Recent theoretical studies have suggested that the dust scattering at the…
Model of a gap formed by a planet with fast inward migration
Kazuhiro D. Kanagawa, Hideko Nomura, Takashi Tsukagoshi +2
A planet is formed within a protoplanetary disk. Recent observations have revealed substructures such as gaps and rings, which may indicate forming planets within the disk. Due to…
