Primeval very low-mass stars and brown dwarfs -- VIII. The first age benchmark L subdwarf, a wide companion to a halo white dwarf
Z. H. Zhang, R. Raddi, A. J. Burgasser +12
We report the discovery of five white dwarf + ultracool dwarf systems identified as common proper motion wide binaries in the Gaia Catalogue of Nearby Stars. The discoveries includ…
The Gaia Ultracool Dwarf Sample -- V: The Ultracool Dwarf Companion catalogue
Sayan Baig, R. L. Smart, Hugh R. A. Jones +4
We present the Ultracool Dwarf Companion Catalogue of 278 multiple systems, 32 of which are newly discovered, each with at least one spectroscopically confirmed Ultracool Dwarf, wi…
Precise Bolometric Luminosities and Effective Temperatures of 23 late-T and Y dwarfs Obtained with JWST
Samuel A. Beiler, Michael C. Cushing, J. Davy Kirkpatrick +5
We present infrared spectral energy distributions of 23 late-type T and Y dwarfs obtained with the James Webb Space Telescope. The spectral energy distributions consist of NIRSpec…
Euclid: Early Release Observations -- A glance at free-floating new-born planets in the sigma Orionis cluster
E. L. Martín, M. {Ž}erjal, H. Bouy +175
We provide an early assessment of the imaging capabilities of the Euclid space mission to probe deeply into nearby star-forming regions and associated very young open clusters, and…
Gaia DR3 detectability of unresolved binary systems
Alfred Castro-Ginard, Zephyr Penoyre, Andrew R. Casey +10
Gaia can not individually resolve very close binary systems, however, the collected data can still be used to identify them. A powerful indicator of stellar multiplicity is the sou…
TOI-4336 A b: A temperate sub-Neptune ripe for atmospheric characterization in a nearby triple M-dwarf system
M. Timmermans, G. Dransfield, M. Gillon +54
Small planets transiting bright nearby stars are essential to our understanding of the formation and evolution of exoplanetary systems. However, few constitute prime targets for at…
