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…
