A 500 pc volume-limited sample of hot subluminous stars

Astronomy & Astrophysics
We present a quantitative spectroscopic and kinematic analysis of a volume-complete sample of hot subluminous stars within 500 pc of the Sun, assembled using accurate parallax measurements from the Gaia space mission Data Release 3 (DR3).

NIKA2 unveils and pinpoints the Planck compact sources

Astronomy & Astrophysics
Context. The Planck Catalogue of Compact Sources (PCCS2) is an unbiased census of the millimetre sky at sub-Jansky levels, and thus a valuable resource for studies of galaxy evolution.

Component masses in stellar and sub-stellar binaries from Gaia astrometry and photometry

Astronomy & Astrophysics
The masses of stars and planets can be measured dynamically in binary systems. For an unresolved binary, time series astrometry reveals the orbital parameters, but it cannot provide the component masses, because we observe only the motion of the system's

The origin of B-type runaway stars based on kinematics

Astronomy & Astrophysics
Context. Runaway stars depart their birthplaces with high peculiar velocities. Two mechanisms are commonly invoked to explain their origin, the binary supernova scenario and the dynamical ejection scenario.
