An Isolated Stellar-Mass Black Hole Detected Through Astrometric Microlensing

Kailash C. Sahu, Jay Anderson, Stefano Casertano +90

We report the first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH). We used the Hubble Space Telescope (HST) to carry out precise astrometry…

A comparison between X-shooter spectra and PHOENIX models across the HR-diagram

A. Lançon, A. Gonneau, K. Verro +14

The path towards robust near-infrared extensions of stellar population models involves the confrontation between empirical and synthetic stellar spectral libraries across the wavel…

Leveraging HST with MUSE: I. Sodium abundance variations within the 2 Gyr-old cluster NGC 1978

S. Saracino, S. Kamann, C. Usher +10

Nearly all of the well studied ancient globular clusters (GCs), in the Milky Way and in nearby galaxies, show star-to-star variations in specific elements (e.g., He, C, N, O, Na, A…

A stellar census in globular clusters with MUSE -- Extending the CaT-metallicity relation below the horizontal branch and applying it to multiple populations

Tim-Oliver Husser, Marilyn Latour, Jarle Brinchmann +7

Aims. We use the spectra of more than 30,000 red giant branch (RGB) stars in 25 globular clusters (GC), obtained within the MUSE survey of Galactic globular clusters, to calibrate…

An Eclipsing Substellar Binary in a Young Triple System discovered by SPECULOOS

Amaury H. M. J. Triaud, Adam J. Burgasser, Artem Burdanov +18

Mass, radius, and age are three of the most fundamental parameters for celestial objects, enabling studies of the evolution and internal physics of stars, brown dwarfs, and planets…

How stellar rotation shapes the colour magnitude diagram of the massive intermediate-age star cluster NGC 1846

Sebastian Kamann, Nate Bastian, Seth Gossage +19

We present a detailed study of stellar rotation in the massive 1.5 Gyr old cluster NGC 1846 in the Large Magellanic Cloud. Similar to other clusters at this age, NGC 1846 shows an…
