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…
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…
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…
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…
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…
Spectral characterisation of the extinction properties of NGC 3603 using JWST NIRSpec
Ciarán Rogers, Bernhard Brandl, Guido de Marchi
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 ma…
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…
Determining stellar accretion rates from and emission lines with JWST NIRSpec
Ciaràn Rogers, Guido de Marchi, Bernhard Brandl
In this letter we present the first systematic spectroscopic measurements of the Near-InfraRed (NIR) hydrogen recombination lines Paschen alpha ( ) and Brackett…
The early evolution of young massive clusters. II. The kinematic history of NGC 6618 / M 17
Mitchel Stoop, Annelotte Derkink, Lex Kaper +5
The fraction of massive stars in young stellar clusters is of importance as they are the dominant sources of both mechanical and radiative feedback, strongly influencing the therma…
Quantifying the contamination from nebular emission in NIRSpec spectra of massive star forming regions
Ciaran R. Rogers, Guido De Marchi, Giovanna Giardino +3
The Near InfraRed Spectrograph (NIRSpec) on the James Webb Space Telescope (JWST) includes a novel micro shutter array (MSA) to perform multi object spectroscopy. While the MSA is…
