Exploring the 100 au Scale Structure of the Protobinary System NGC 2264 CMM3 with ALMA

Yoshiki Shibayama, Yoshimasa Watanabe, Yoko Oya +8

We have observed the young protostellar system NGC 2264 CMM3 in the 1.3 mm and 2.0 mm bands at a resolution of about 0.1 (70 au) with ALMA. The structures of two distinct compon…

Rotating Motion of the Outflow of IRAS 16293-2422 A1 at its Origin Point near the Protostar

Yoko Oya, Yoshimasa Watanabe, Ana López-Sepulcre +4

The Class 0 protostar IRAS 162932422 Source A is known to be a binary system (A1 and A2) or even a multiple system, which processes a complex outflow structure. We have observed…

FAUST II. Discovery of a Secondary Outflow in IRAS 15398-3359: Variability in Outflow Direction during the Earliest Stage of Star Formation?

Yuki Okoda, Yoko Oya, Logan Francis +66

We have observed the very low-mass Class 0 protostar IRAS 15398-3359 at scales ranging from 50 au to 1800 au, as part of the ALMA Large Program FAUST. We uncover a linear feature,…
