Ring Gap Structure around Class I Protostar WL 17
Ayumu Shoshi, Naoto Harada, Kazuki Tokuda +7
WL 17 is a Class I object and was considered to have a ring-hole structure. We analyzed the structure around WL 17 to investigate the detailed properties of WL 17. We used ALMA arc…
An ALMA-resolved view of 7000 au Protostellar Gas Ring around the Class I source CrA-IRS 2 as a possible sign of magnetic flux advection
Kazuki Tokuda, Naofumi Fukaya, Kengo Tachihara +5
Transferring a significant fraction of the magnetic flux from a dense cloud core is essential in the star formation process. A ring-like structure produced by magnetic flux loss ha…
Secondary outflow driven by the protostar Ser-emb 15 in Serpens
Asako Sato, Kazuki Tokuda, Masahiro N. Machida +6
We present the detection of a secondary outflow associated with a Class I source, Ser-emb 15, in the Serpens Molecular Cloud. We reveal two pairs of molecular outflows consisting o…
The Detection of Higher-Order Millimeter Hydrogen Recombination Lines in the Large Magellanic Cloud
Marta Sewiło, Kazuki Tokuda, Stan E. Kurtz +10
We report the first extragalactic detection of the higher-order millimeter hydrogen recombination lines (). The -, -, and -transitions have been detected toward the…
An ALMA Glimpse of Dense Molecular Filaments Associated with High-mass Protostellar Systems in the Large Magellanic Cloud
Kazuki Tokuda, Naoto Harada, Kei E. I. Tanaka +10
Recent millimeter/sub-millimeter facilities have revealed the physical properties of filamentary molecular clouds in relation to high-mass star formation. A uniform survey of the n…
Crescent-Shaped Molecular Outflow from the Intermediate-mass Protostar DK Cha Revealed by ALMA
Naoto Harada, Kazuki Tokuda, Hayao Yamasaki +6
We report on an Atacama Large Millimeter/submillimeter Array (ALMA) study of the Class I or II intermediate-mass protostar DK Cha in the Chamaeleon II region. The 12CO (J=2-1) imag…
