Multiple Stellar Populations in 47 Tucanae
We use Hubble Space Telescope (HST) and ground-based imaging to study the multiple populations of 47 Tucanae (47 Tuc), combining high-precision photometry with...
Multiple stellar populations in Magellanic Cloud clusters - III. The first evidence of an extended main sequence turn-off in a young cluster: NGC 1856
Recent studies have shown that the extended main-sequence turn-off (eMSTO) is a common feature of intermediate-age star clusters in the Magellanic Clouds (MCs)...
Multiple stellar populations in Magellanic Cloud clusters. II. Evidence also in the young NGC 1844?
We used Hubble Space Telescope observations to study the young cluster NGC 1844 in the Large Magellanic Cloud (LMC). We estimated the fraction and the mass...
Multiplicity among the cool supergiants in the Magellanic Clouds
The characterization of multiplicity of high-mass stars is of fundamental importance to understand their evolution, the diversity of observed core-collapse...
Multiplicity of the red supergiant population in the young massive cluster NGC 330
Context. The multiplicity properties of massive stars are one of the important outstanding issues in stellar evolution. Quantifying the binary statistics of all...
Multiwavelength Observations of the Black Hole Transient XTE J1752–223 during Its 2010 Outburst Decay
Galactic black hole transients show many interesting phenomena during outburst decays. We present simultaneous X-ray (RXTE, Swift, and INTEGRAL), and optical...
MuSCAT2 multicolour validation of TESS candidates: an ultra-short-period substellar object around an M dwarf
Context. We report the discovery of TOI 263.01 (TIC 120916706), a transiting substellar object (R = 0.87 R Jup) orbiting a faint M3.5 V dwarf (V = 18.97) on a 0...
MUSE spectroscopy of planetary nebulae with high abundance discrepancies
We present MUSE deep integral-field unit spectroscopy of three planetary nebulae (PNe) with high-abundance discrepancy factors (ADF > 20): NGC 6778, M 1-42, and...
MUSSES2020J: The Earliest Discovery of a Fast Blue Ultraluminous Transient at Redshift 1.063
In this Letter, we report the discovery of an ultraluminous fast-evolving transient in rest-frame UV wavelengths, MUSSES2020J, soon after its occurrence by...
