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…
Disk or Companion: Characterizing Excess Infrared Flux in Seven White Dwarf Systems with Near-Infrared Spectroscopy
Dylan Owens, Siyi Xu, Elena Manjavacas +7
Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations with…
A Spectro-photometric Analysis of Cool White Dwarfs in the Gaia and Pan-STARRS Footprint
Alexandre Caron, Pierre Bergeron, Simon Blouin +1
We present a spectro-photometric analysis of 2880 cool white dwarfs within 100 pc of the Sun and cooler than Teff = 10,000 K, with grizy Pan-STARRS photometry and Gaia trigonometri…
On the Nature of Ultracool White Dwarfs: Not so Cool Afterall
P. Bergeron, Mukremin Kilic, Simon Blouin +3
A recent analysis of the 100 pc white dwarf sample in the SDSS footprint demonstrated for the first time the existence of a well defined ultracool -- or IR-faint -- white dwarf seq…
Gemini/GMOS Transmission Spectroscopy of the Grazing Planet Candidate WD 1856+534 b
Siyi Xu, Hannah Diamond-Lowe, Ryan J. MacDonald +12
WD 1856+534 b is a Jupiter-sized, cool giant planet candidate transiting the white dwarf WD 1856+534. Here, we report an optical transmission spectrum of WD 1856+534 b obtained fro…
Ultracool Dwarfs Observed with the Spitzer Infrared Spectrograph. I. An Accurate Look at the L-to-T Transition at 300 Myr from Optical through Mid-infrared Spectrophotometry
Genaro Suárez, Stanimir Metchev, Sandy K. Leggett +2
We present IRS 5--14 m spectra and 16 m and 22 m photometry of the T2.5 companion to the 300 Myr-old G0V star HN Peg. We incorporate previous 0.8--5 m o…
