Molecular and Atomic Gas Associated with the Gamma Ray Supernova Remnant RCW 103
H. Inoue, Y. Asano, R. G. Bhuvana +15
We present a study of the interstellar molecular and atomic gas associated with the gamma-ray supernova remnant (SNR) RCW 103 using the Mopra CO( = 1-0), Atacama Large Mi…
Protoplanetary Disk Evolution in a Low-Metallicity Environment: JWST's First Mid-Infrared Census of Low-Mass Stars
Chikako Yasui, Natsuko Izumi, Masao Saito +3
This study presents the first high-resolution, high-sensitivity mid-infrared (MIR) investigation of protoplanetary disks in a low-metallicity environment, using JWST/NIRCam and MIR…
Digging into the chemical complexity in the outer Galaxy: A hot molecular core in Sharpless 2-283
Toki Ikeda, Takashi Shimonishi, Hiroyuki Kaneko +3
The outer Galaxy (galactocentric distance 13.5 kpc) serves as an excellent laboratory for investigating the chemical complexity in low-metallicity environments. Here, we p…
The detection of spatially resolved protosteller outflows and episodic jets in the outer Galaxy
Toki Ikeda, Takashi Shimonishi, Natsuko Izumi +5
We present the first detection of spatially resolved protostellar outflows and jets in the outer Galaxy. We observed five star-forming regions in the outer Galaxy (Sh 2--283, NOMF0…
Revealing Potential Initial Mass Function variations with metallicity: JWST observations of young open clusters in a low-metallicity environment
Chikako Yasui, Natsuko Izumi, Masao Saito +3
We present the substellar mass function of star-forming clusters (0.1 Myr old) in a low-metallicity environment (0.7 dex). We performed deep JWST/NIRCam and MIRI…
Overview Results of JWST Observations of Star-Forming Clusters in the Extreme Outer Galaxy
Natsuko Izumi, Michael E. Ressler, Ryan M. Lau +4
The extreme outer Galaxy (EOG), which we define as the region of the Milky Way with a galactocentric radius of more than 18 kpc, provides an excellent opportunity to study star for…
