GREX-PLUS Science Book v2
PLUS Science Team, Shunsuke Baba, Sirio Belli +52
GREX-PLUS (Galaxy Reionization EXplorer and PLanetary Universe Spectrometer) is a mission candidate for a JAXA strategic L-class mission to be launched in the 2030s. Its primary sc…
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…
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…
MAGIS (Measuring Abundances of red super Giants with Infrared Spectroscopy) project I. Establishment of an abundance analysis procedure for red supergiants and its evaluation with nearby stars
Daisuke Taniguchi, Noriyuki Matsunaga, Naoto Kobayashi +11
[Abbreviated] Context. Given their high luminosities (L>~10^4Lsun), red supergiants (RSGs) are good tracers of the chemical abundances of the young stellar population in the Milky…
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…
