Discovery of metal-poor and distant pre-main sequence candidates in WLM with JWST
Venu M. Kalari, Ricardo Salinas, Morten Andersen +4
We present the discovery of twelve metal-poor and distant pre-main sequence (PMS) candidates in the dwarf irregular galaxy Wolf-Lundmark-Melotte (WLM)~968 kpc away, at a present-da…
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…
A sextet of clusters in the Vela OB2 region revealed by Gaia
Giacomo Beccari, Henri M. J. Boffin, Tereza Jerabkova +5
Using Gaia DR2 data, combined with OmegaCAM ground-based optical photometry from the AD-HOC survey, and detailed Radial Velocity measurements from ESO-Gaia, we analyse in detail a…
Photometric determination of the mass accretion rates of pre-main sequence stars. V. Recent star formation in the 30 Dor nebula
Guido De Marchi, Nino Panagia, Giacomo Beccari
We report on the properties of the low-mass stars that recently formed in the central ~ 2.7'x2.7' of 30 Dor including the R136 cluster. Using the photometric catalogue of De Marchi…
