Disk-Driven Rotating Bipolar Outflow in Orion Source I

Tomoya Hirota, Masahiro N. Machida, Yuko Matsushita +5

One of the outstanding problems in star-formation theory concerns the transfer of angular momentum such that mass can accrete onto a newly born young stellar object (YSO). From a t…

The Difference in Abundances between N-bearing and O-bearing Species in High-Mass Star-Forming Regions

Taiki Suzuki, Masatoshi Ohishi, Masao Saito +3

The different spatial distributions of N-bearing and O-bearing species, as is well known towards Orion~KL, is one of the long-lasting mysteries. We conducted a survey observation a…

ALMA observations of submillimeter H2O and SiO lines in Orion Source I

Tomoya Hirota, Masahiro N. Machida, Yuko Matsushita +5

We present observational results of the submillimeter H2O and SiO lines toward a candidate high-mass young stellar object Orion Source I using ALMA. The spatial structures of the h…

L483: Warm Carbon-Chain Chemistry Source Harboring Hot Corino Activity

Yoko Oya, Nami Sakai, Yoshimasa Watanabe +11

The Class 0 protostar, L483, has been observed in various molecular lines in the 1.2 mm band at a sub-arcsecond resolution with ALMA. An infalling-rotating envelope is traced by th…

Trigonometric distance and proper motions of H2O maser bowshocks in AFGL 5142

Ross A. Burns, Toshihiro Handa, Hiroshi Imai +6

We present the results of multi-epoch VLBI observations of water masers in the AGFL 5142 massive star forming region. We measure an annual parallax of mas, corr…
