A study of Be stars in the Magellanic Clouds [PDF]

, 2013
We present the results of a photometric survey for Be stars in eleven young clusters in the Large Magellanic Cloud and fourteen young clusters in the Small Magellanic Cloud. B stars with hydrogen in emission are identified on the basis of their R-H{\alpha} colour.

Search for Gamma-ray Emission from Dark Matter Annihilation in the Small Magellanic Cloud with the Fermi Large Area Telescope [PDF]

, 2016
The Small Magellanic Cloud (SMC) is the second-largest satellite galaxy of the Milky Way and is only 60 kpc away. As a nearby, massive, and dense object with relatively low astrophysical backgrounds, it is a natural target for dark matter indirect ...

THORIUM LINES IN THE SPECTRA OF SEVERAL SMC SUPERGIANT STARS

Odessa Astronomical Publications, 2007
We present the results of identifications of the Th II lines in the spectra of four stars in the Small Magellanic Cloud: PMMR 23, PMMR 39,PMMR144, and PMMR 145.

Massive stars in the Small Magellanic Cloud

, 2021
Context. The evolution of massive stars depends on several physical processes and parameters. Metallicity and rotation are among the most important, but their quantitative effects are not well understood.Aims. To complement our earlier study on main-sequence stars, we study the evolutionary and physical properties of evolved O stars in the Small ...

Untangling Magellanic Streams

The Open Journal of Astrophysics
The Magellanic Stream (MS) is known to contain multiple HI strands and corresponding stellar populations are being discovered. Combining a sample of 17 stars from the H3 (“Hectochelle in the Halo at High Resolution”) survey with 891 stars drawn from the

Evidence of Galactic Interaction in the Small Magellanic Cloud Probed by Gaia-selected Massive Star Candidates

The Astrophysical Journal Supplement Series
We present identifications and kinematic analysis of 7426 massive (≥8 M _⊙ ) stars in the Small Magellanic Cloud (SMC), using Gaia DR3 data. We used the Gaia ( G _BP − G _RP , G ) color–magnitude diagram to select the population of massive stars, and ...

The Dark Energy Camera Magellanic Clouds Emission-line Survey

The Astrophysical Journal
We have used the Dark Energy Camera (DECam) on the CTIO Blanco 4 m telescope to perform a new emission-line survey of the Large Magellanic Cloud (LMC) using narrowband H α and [S ii ] filters in addition to a continuum band to create pure emission-line ...

Scylla. II. The Spatially Resolved Star Formation History of the Large Magellanic Cloud Reveals an Inverted Radial Age Gradient

The Astrophysical Journal
The proximity of the Magellanic Clouds provides the opportunity to study interacting dwarf galaxies near a massive host, and spatial trends in their stellar population properties in particular, with a unique level of detail.
