Stellar masses and ages in Gaia Data Release 4 from the Final Luminosity Age Mass Estimator algorithm

Orlagh L. Creevey, Laia Casamiquela, Yveline Lebreton +23

The masses and ages of stars are key quantities for understanding exoplanetary, stellar, and galactic evolution. In the context of Gaia, these parameters provide insights into the…

The primordial nature of the C-19 stellar stream

Kim A. Venn, Zhen Yuan, Nicolas F. Martin +32

Stellar streams, remnants of compact star systems stretched out by the tidal forces of the Milky Way, offer a unique way to study stellar populations that formed billions of years…

The Effect of a Non-universal Extinction Curve on the Wesenheit Function and Cepheid Distances

D. M. Skowron, M. L. Fouesneau, R. Drimmel +1

The Wesenheit function is widely used to reduce the effects of interstellar reddening in distance measurements. Its construction, however, relies on the assumption of a universal e…

GaiaUnlimited: The old stellar disc of the Milky Way as traced by the Red Clump

Shourya Khanna, Jie Yu, Ronald Drimmel +9

We present an exploration of the Milky Way's structural parameters using an all-sky sample of RC giants to map the stellar density from the Galactic disc beyond 3 kpc. These evolve…

The completeness of the open cluster census towards the Galactic anticentre

Emily L. Hunt, Tristan Cantat-Gaudin, Friedrich Anders +9

Open clusters have long been used as tracers of Galactic structure. However, without a selection function to describe the completeness of the cluster census, it is difficult to qua…

Strikingly high fraction of fast rotators in Magellanic Cloud star clusters

Greta Ettorre, Alessandro Mazzi, Leo Girardi +14

There has been growing evidence that the rich star clusters in the Magellanic Clouds contain significant fractions of rapidly rotating stars. In this work, we aim to constrain thes…
