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…

Kinematic evidence of magnetospheric accretion for Herbig Ae stars with JWST NIRSpec

Ciarán Rogers, Bernhard Brandl, Guido de Marchi

Hydrogen emission lines have been used to estimate the mass accretion rate of pre-main-sequence stars for over years, although the physical origin of these lines is still uncl…

Externally irradiated young stars in NGC 3603. A JWST NIRSpec catalogue of pre-main-sequence stars in a massive star formation region

Ciarán Rogers, Guido de Marchi, Bernhard Brandl

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 allow…

The past, present and future of observations of externally irradiated disks

Planet formation environments collaboration, Megan Allen, Rossella Anania +51

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 evolutio…
