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…

Chemical Signatures of AGB Mass Transfer in Gaia White Dwarf Companions

Natsuko Yamaguchi, Kareem El-Badry, Henrique Reggiani +2

We present a homogeneous abundance analysis of 160 main-sequence stars in astrometric white-dwarf + main-sequence (WD+MS) binaries with orbits from Gaia DR3. These systems have AU-…

A Spectroscopic Search for Dormant Black Holes in Low-Metallicity Binaries

Pranav Nagarajan, Kareem El-Badry, Henrique Reggiani +9

The discovery of the massive black hole (BH) system Gaia BH3 in pre-release Gaia DR4 data suggests that wide BH binaries with luminous companions may be significantly overrepresent…

A population of neutron star candidates in wide orbits from Gaia astrometry

Kareem El-Badry, Hans-Walter Rix, David W. Latham +10

We report discovery and spectroscopic follow-up of 21 astrometric binaries containing solar-type stars and dark companions with masses near 1.4 . The simplest interpreta…

What Does the Large Magellanic Cloud Look Like? It Depends on [M/H] and Age

Neige Frankel, Rene Andrae, Hans-Walter Rix +2

We offer a new way to look at the Large Magellanic Cloud through stellar mono-abundance and mono-age-mono-abundance maps. These maps are based on member stars wi…

The Three-Phase Evolution of the Milky Way

Vedant Chandra, Vadim A. Semenov, Hans-Walter Rix +6

We illustrate the formation and evolution of the Milky Way over cosmic time, utilizing a sample of 10 million red giant stars with full chemodynamical information, including metall…
