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…

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…

Young Stellar Objects in NGC 346: A JWST NIRCam/MIRI Imaging Survey

Nolan Habel, Conor Nally, Laura Lenkic +17

We present a JWST imaging survey with NIRCam and MIRI of NGC 346, the brightest star-forming region in the Small Magellanic Cloud (SMC). By combining aperture and point spread func…

Emission lines due to ionizing radiation from a compact object in the remnant of Supernova 1987A

C. Fransson, M. J. Barlow, P. J. Kavanagh +31

The nearby Supernova 1987A was accompanied by a burst of neutrino emission, which indicates that a compact object (a neutron star or black hole) was formed in the explosion. There…
