Gaia Data Release 3 contains a wealth of new data products for the community.
Astrophysical parameters are a major component of this release, and were produced by the …

Abstract The Dark Energy Spectroscopic Instrument (DESI) is carrying out a five-year survey
that aims to measure the redshifts of tens of millions of galaxies and quasars, including 8 …

Context. The multiplicity fraction of stars, down to the substellar regime, is a parameter of
fundamental importance for stellar formation, evolution, and planetology. The census of …

Galactic haloes in a Λ-CDM universe are predicted to host today a swarm of debris resulting
from cannibalized dwarf galaxies. The chemodynamical information recorded in their stellar …

Context. In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M
dwarfs provide unique opportunities for characterising their atmospheres, as well as …

Benchmark brown dwarf companions with well-determined ages and model-independent
masses are powerful tools to test substellar evolutionary models and probe the formation of …

We report the discovery of a candidate binary system consisting of a black hole (BH) and a
red giant branch star in Gaia DR3. This binary system was discovered from 64,108 binary …

In light of substantial new discoveries of hot subdwarfs by ongoing spectroscopic surveys
and the availability of the Gaia mission Early Data Release 3 (EDR3), we compiled new …

Axions with couplings ga γ γ∼ few× 10-11 GeV-1 to electromagnetism may resolve a
number of astrophysical anomalies, such as unexpected∼ TeV transparency, anomalous …

Abstract Massive stars (∼ 8–25 M⊙) stripped of their hydrogen-rich envelopes via binary
interaction are thought to be the main progenitors for merging neutron stars and stripped …
