JWST 1.5 μm and 4.8 μm Photometry of Y Dwarfs
Loïc Albert, Sandy K. Leggett, Per Calissendorff +20
Brown dwarfs lack nuclear fusion and cool with time; the coldest known have an effective temperature below 500 K, and are known as Y dwarfs. We present a James Webb Space Telescope…
Discovery of astrometric accelerations by dark companions in the globular cluster Centauri
Imants Platais, Johannes Sahlmann, Leo Girardi +6
We present results from the search for astrometric accelerations of stars in Centauri using 13 years of regularly-scheduled {\it Hubble Space Telescope} WFC3/UVIS calibration o…
Substellar science in the wake of the ESA Euclid space mission
Eduardo L. Martín, Hervé Bouy, Diego Martín +16
The ESA space mission Euclid was launched on July 1st, 2023 and is undergoing its science verification phase. In this invited review we show that Euclid means a before and an after…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…
JWST/NIRCam discovery of the first Y+Y brown dwarf binary: WISE J033605.05014350.4
Per Calissendorff, Matthew De Furio, Michael Meyer +25
We report the discovery of the first brown dwarf binary system with a Y dwarf primary, WISE J033605.05014350.4, observed with NIRCam on JWST with the F150W and F480M filters. We…
