The Stellar Population of NGC 346 in the Small Magellanic Cloud with JWST

J. Jaspers, P. Kavanagh, G. De Marchi +13

NGC 346 is a massive star-forming region located at a distance of 62 kpc, in the Small Magellanic Cloud (SMC). Due to its low metallicity (Z 1/5 Z), it is an…

JWST NIRCam and MIRI Reveal the Dust-Producing AGB Population of NGC 6822

Conor Nally, Olivia C. Jones, Laura Lenkić +9

We present a photometric catalogue of the Local Group dwarf galaxy NGC 6822 based on deep JWST observations obtained with the Near-Infrared Camera (NIRCam) and Mid-Infrared Instrum…

A Mid-Infrared Spectroscopic Study of Young Stellar Objects in the SMC Region NGC 346: JWST Detects Dust, Accretion, Ices and Outflows

Nolan Habel, Omnarayani Nayak, Patrick J. Kavanagh +13

We present mid-infrared spectroscopic observations of intermediate- to high-mass young stellar objects (YSOs) in the low-metallicity star-forming region NGC 346 located within the…

Investigating the metallicity dependence of the mass-loss rate relation of red supergiants

K. Antoniadis, E. Zapartas, A. Z. Bonanos +8

Red supergiants (RSGs) are cool and evolved massive stars exhibiting enhanced mass loss compared to their main sequence phase, affecting their evolution and fate. However, the theo…

Protoplanetary discs around sun-like stars appear to live longer when the metallicity is low

Guido De Marchi, Giovanna Giardino, Katia Biazzo +17

Previous Hubble Space Telescope (HST) observations of the star-forming cluster NGC 346 in the Small Magellanic Cloud (SMC) had revealed a large population of pre-main sequence (PMS…

Imaging of I Zw 18 by JWST: II. Spatially resolved star formation history

Giacomo Bortolini, Göran Östlin, Nolan Habel +14

The blue compact dwarf galaxy I Zw 18 is one of the most metal-poor () star-forming galaxies in the local Universe. Its evolutionary status has sparked debate w…

Imaging of I Zw 18 by JWST. I. Strategy and First Results of Dusty Stellar Populations

Alec S. Hirschauer, Nicolas Crouzet, Nolan Habel +16

We present a JWST imaging survey of I Zw 18, the archetypal extremely metal-poor, star-forming (SF), blue compact dwarf galaxy. With an oxygen abundance of only 3% $Z_{\odot}…
