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…

On the universal validity of Case B recombination theory

C. Scarlata, M. Hayes, N. Panagia +3

In an ongoing search for low-mass extreme emission line galaxies, we identified a galaxy with a Ha/Hb Balmer line ratio of 2.620 +- 0.078. Ha/Hb Balmer ratios lower than the dust-f…

Photometric determination of the mass accretion rates of pre-main sequence stars. VII. The low-density cluster NGC 376 in the Small Magellanic Cloud

Styliani Tsilia, Guido De Marchi, Nino Panagia

Aims. We study the properties of low-mass stars recently formed in the field of the NGC 376 cluster in the Small Magellanic Cloud (SMC). Methods. Using photometric observations acq…

Discovery of dusty sub-solar mass young stellar objects in NGC 346 with JWST/NIRCam

Olivia C. Jones, Conor Nally, Nolan Habel +23

JWST observations of NGC 346, a star-forming region in the metal-poor Small Magellanic Cloud, reveal a substantial population of sub-solar mass young stellar objects (YSOs) with IR…

Pre-main Sequence stars in LH91

R. Carini, K. Biazzo, G. De Marchi +3

We study the accretion properties of pre-main sequence low-mass stars in the LH 91 association within the Large Magellanic Clouds. Using optical multiband photometry obtained with…

Extinction in the Large Magellanic Cloud Bar around NGC1854, NGC1856, and NGC1858

Guido De Marchi, Nino Panagia, Antonino P. Milone

We report on the extinction properties in the fields around the clusters NGC 1854, NGC 1856, and NGC 1858 in the bar of the Large Magellanic Cloud. The colour-magnitude diagrams of…
