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…

JWST Observations of the Enigmatic Y Dwarf WISE 1828+2650: I. Limits to a Binary Companion

Matthew De Furio, Ben W. Lew, Charles A. Beichman +20

The Y-dwarf WISE 1828+2650 is one of the coldest known Brown Dwarfs with an effective temperature of 300 K. Located at a distance of just 10 pc, previous model-based estimate…

First Observations of the Brown Dwarf HD 19467 B with JWST

Alexandra Z. Greenbaum, Jorge Llop-Sayson, Ben Lew +21

We observed HD 19467 B with JWST's NIRCam in six filters spanning 2.5-4.6 with the Long Wavelength Bar coronagraph. The brown dwarf HD 19467 B was initially identified through…

The Small Separation A-Star Companion Population: First Results with CHARA/MIRC-X

Matthew De Furio, Tyler Gardner, John Monnier +9

We present preliminary results from our long-baseline interferometry (LBI) survey to constrain the multiplicity properties of intermediate-mass A-type stars within 80pc. Previous m…

Updated orbital monitoring and dynamical masses for nearby M-dwarf binaries

Per Calissendorff, Markus Janson, Laetitia Rodet +26

Young M-type binaries are particularly useful for precise isochronal dating by taking advantage of their extended pre-main sequence evolution. Orbital monitoring of these low-mass…

Binary Formation in the Orion Nebula Cluster: Exploring the Sub-stellar Limit

Matthew De Furio, Michael R. Meyer, Megan Reiter +3

We present results constraining the multiplicity of the very low mass stars and sub-stellar objects in the Orion Nebula Cluster (ONC). Our sample covers primary masses 0.012-0.1M$_…
