Disk Wind Feedback from High-mass Protostars. IV. Shock-Ionized Jets
Emiko C. Gardiner, Jonathan C. Tan, Jan E. Staff +3
Massive protostars launch accretion-powered, magnetically-collimated outflows, which play crucial roles in the dynamics and diagnostics of the star formation process. Here we calcu…
Disk Wind Feedback from High-mass Protostars. III. Synthetic CO Line Emission
Duo Xu, Jonathan C. Tan, Jan E. Staff +3
To test theoretical models of massive star formation it is important to compare their predictions with observed systems. To this end, we conduct CO molecular line radiative transfe…
Chemical evolution of some selected complex organic molecules in low-mass star-forming regions
Bratati Bhat, Rumela Kar, Suman Kumar Mondal +6
The destiny of complex organic molecules (COMs) in star-forming regions is interlinked with various evolutionary phases. Therefore, identifying these species in diversified environ…
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…
Observational signatures of forming young massive clusters: continuum emission from dense HII regions
Mutsuko Inoguchi, Takashi Hosokawa, Hajime Fukushima +3
Young massive clusters (YMCs) are the most massive star clusters forming in nearby galaxies and are thought to be a young analogue to the globular clusters. Understanding the forma…
The Detection of Hot Molecular Cores in the Small Magellanic Cloud
Takashi Shimonishi, Kei E. I. Tanaka, Yichen Zhang +1
We report the first detection of hot molecular cores in the Small Magellanic Cloud, a nearby dwarf galaxy with 0.2 solar metallicity. We observed two high-mass young stellar object…
Massive Protostellar Disks as a Hot Laboratory of Silicate Grain Evolution
Ryota Yamamuro, Kei E. I. Tanaka, Satoshi Okuzumi
Typical accretion disks around massive protostars are hot enough for water ice to sublimate. We here propose to utilize the massive protostellar disks for investigating the collisi…
Astrochemical Diagnostics of the Isolated Massive Protostar G28.20-0.05
Prasanta Gorai, Chi-Yan Law, Jonathan C. Tan +8
We study the astrochemical diagnostics of the isolated massive protostar G28.20-0.05. We analyze data from ALMA 1.3~mm observations with resolution of 0.2 arcsec (1,000 au).…
Disk Wind Feedback from High-mass Protostars. II. The Evolutionary Sequence
Jan E. Staff, Kei E. I. Tanaka, Jon P. Ramsey +2
Star formation is ubiquitously associated with the ejection of accretion-powered outflows that carve bipolar cavities through the infalling envelope. This feedback is expected to b…
