Buoyant crystals halt the cooling of white dwarf stars

Antoine Bédard, Simon Blouin, Sihao Cheng

White dwarfs are stellar remnants devoid of a nuclear energy source, gradually cooling over billions of years and eventually freezing into a solid state from the inside out. Recent…

The mystery in Gaia DR3 triples: occurrence rates, orientations, and eccentricities of wide tertiaries around close binaries

Hsiang-Chih Hwang

The formation of close binaries has been an open question for decades. A large fraction of close binaries are in triple systems, suggesting that their formation may be associated w…

Enhancement of Double-Close-Binary Quadruples

Gavin B. Fezenko, Hsiang-Chih Hwang, Nadia L. Zakamska

Double-close-binary quadruples (2+2 systems) are hierarchical systems of four stars where two short-period binary systems move around their common center of mass on a wider orbit.…

Detailed elemental abundances of binary stars: Searching for signatures of planet formation and atomic diffusion

Fan Liu, Bertram Bitsch, Martin Asplund +5

Binary star systems are assumed to be co-natal and coeval, thus to have identical chemical composition. In this work we aim to test the hypothesis that there is a connection betwee…

Rotation and Lithium Confirmation of a 500 Parsec Halo for the Open Cluster NGC 2516

L. G. Bouma, J. L. Curtis, J. D. Hartman +2

Recent analyses of the Gaia data have identified diffuse stellar populations surrounding nearby open clusters. It is important to verify that these "halos", "tails", and "strings"…

Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit

Nolan Grieves, François Bouchy, Monika Lendl +52

We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exopla…
