Spectroscopic Evidence for Gas Infall in GF9-2
Ray S. Furuya, Yoshimi Kitamura, Hiroko Shinnaga
We present spectroscopic evidence for infall motion of gas in the natal cloud core harboring an extremely young low-mass protostar GF9-2. We previously discussed that the ongoing c…
Candidate Rotating Toroids around High-Mass (Proto)Stars
R. S. Furuya, R. Cesaroni, S. Takahashi +3
Using the OVRO, Nobeyama, and IRAM mm-arrays, we searched for ``disk''-outflow systems in three high-mass (proto)star forming regions: G16.59-0.05, G23.01-0.41, and G28.87+0.07. Th…
Infall of gas as the formation mechanism of stars up to 20 times more massive than the Sun
Maria T. Beltran, Riccardo Cesaroni, Claudio Codella +3
Theory predicts and observations confirm that low-mass stars (like the Sun) in their early life grow by accreting gas from the surrounding material. But for stars ~ 10 times more m…
The Initial Conditions for Gravitational Collapse of a Core: An Extremely Young Low-Mass Class 0 Protostar GF9-2
Ray S. Furuya, Yoshimi Kitamura, Hiroko Shinnaga
We present a study of the natal core harboring the class 0 protostar GF9-2 in the filamentary dark cloud GF 9 (d = 200 pc). GF9-2 stands unique in the sense that it shows H2O maser…
Proper Motion of H2O Masers in IRAS 20050+2720 MMS1: An AU Scale Jet Associated with An Intermediate-Mass Class 0 Source
Ray S. Furuya, Yoshimi Kitamura, Alwyn Wootten +2
We conducted a 4 epoch 3 month VLBA proper motion study of HO masers toward an intermediate-mass class 0 source IRAS 20050+2720 MMS1 (d=700 pc). From milli-arcsecond (mas) reso…
A detailed study of the rotating toroids in G31.41+0.31 and G24.78+0.08
Maria T. Beltran, Riccardo Cesaroni, Roberto Neri +4
We present the results of high angular resolution millimeter observations of gas and dust toward G31.41+0.31 and G24.78+0.08, two high-mass star forming regions where four rotating…
