First Detection of Ices in Intermediate-mass Young Stellar Objects beyond the Milky Way Open
Using NIRSpec on JWST, we studied a sample of 15 intermediate-mass (1.8–4.1 M ⊙ ) young stellar objects (YSOs) previously identified with MIRI photometry in the low-metallicity NGC 346 star-forming cluster in the Small Magellanic Cloud. Al…

The past, present and future of observations of externally irradiated disks Open
Recent years have seen a surge of interest in the community studying the effect of ultraviolet radiation environment, predominantly set by OB stars, on protoplanetary disc evolution and planet formation. This is important because a signifi…
Kinematic evidence of magnetospheric accretion for Herbig Ae stars with JWST NIRSpec Open
Context. Hydrogen emission lines have been used to estimate the mass accretion rate of pre-main-sequence stars for over 25 years. Despite the clear correlation between the accretion luminosity of a star and hydrogen line luminosities, the …
Externally irradiated young stars in NGC 3603 Open
Context . NGC 3603 is the optically brightest massive star forming region (SFR) in the Milky Way, representing a small scale starburst region. Studying young stars in regions like this allows us to assess how star and planet formation proc…

Kinematic evidence of magnetospheric accretion for Herbig Ae stars with JWST NIRSpec Open
Hydrogen emission lines have been used to estimate the mass accretion rate of pre-main-sequence stars for over $25$ years, although the physical origin of these lines is still unclear. Magnetospheric accretion (MA) and magneto-centrifugal …
Externally irradiated young stars in NGC 3603. A JWST NIRSpec catalogue of pre-main-sequence stars in a massive star formation region Open
NGC 3603 is the optically brightest massive star forming region (SFR) in the Milky Way, representing a small scale starburst region. Studying young stars in regions like this allows us to assess how star and planet formation proceeds in a …

Protoplanetary Disks around Sun-like Stars Appear to Live Longer When the Metallicity is Low* Open
Previous Hubble Space Telescope observations of the star-forming cluster NGC 346 in the Small Magellanic Cloud (SMC) revealed a large population of pre-main-sequence (PMS) candidates, characterized by H α excess emission in their photometr…

Young Stellar Objects in NGC 346: A JWST NIRCam/MIRI Imaging Survey Open
We present a JWST imaging survey with NIRCam and MIRI of NGC 346, the brightest star-forming region in the Small Magellanic Cloud. By combining aperture and point-spread function photometry of 11 wavelength bands across these two instrumen…
Spectral characterisation of the extinction properties of NGC 3603 using JWST NIRSpec Open
Context . A necessary ingredient in understanding the star formation history of a young cluster is knowledge of the extinction towards the region. This has typically been done by making use of the colour-difference method with photometry, …
