JWST NIRCam and MIRI Reveal the Dust-Producing AGB Population of NGC 6822
Conor Nally, Olivia C. Jones, Laura LenkiÄ +9
The paper presents a JWST NIRCam and MIRI photometric catalogue of the dwarf galaxy NGC 6822, identifies dust‑producing asymptotic giant branch (AGB) stars, and quantifies their du…
Taming the Tarantula: How Stellar Wind Feedback Shapes Gas and Dust in 30 Doradus
Jennifer A. Rodriguez, Laura A. Lopez, Lachlan Lancaster +5
Observations of massive star-forming regions show that classical stellar wind models over-predict the luminosity of the X-ray emitting gas, indicating a significant fraction of win…
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…
First detection of ices in intermediate-mass young stellar objects beyond the Milky Way
Guido De Marchi, Nolan Habel, Margaret Meixner +15
Using NIRSpec on JWST, we studied a sample of 15 intermediate-mass (1.8-4.1 Msun) young stellar objects (YSOs) previously identified with MIRI photometry in the low-metallicity NGC…
JWST NIRCam Imaging of NGC 4258: I. Observation Overview
Travis C. Fischer, Nicholas F. Cothard, Omnarayani Nayak +3
We present James Webb Space Telescope (JWST) NIRCam imaging of the nearby Seyfert 1.9 galaxy NGC 4258, which hosts strong star formation regions as well as an anomalous jet-like ra…
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…
