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…
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…
On the chemical abundances of Miras in clusters: V1 in the metal-rich globular NGC 5927
V. D'Orazi, D. Magurno, G. Bono +50
We present the first spectroscopic abundance determination of iron, alpha-elements (Si, Ca and Ti) and sodium for the Mira variable V1 in the metal-rich globular cluster NGC 5927.…
Star Formation in the Extreme Outer Galaxy: Digel Cloud 2 Clusters
Chikako Yasui, Naoto Kobayashi, Alan T. Tokunaga +2
As a first step for studying star formation in the extreme outer Galaxy (EOG), we obtained deep near-infrared images of two embedded clusters at the northern and southern CO peaks…
