Searching for Planets Orbiting Fomalhaut with JWST/NIRCam

Marie Ygouf, Charles Beichman, Jorge Llop-Sayson +20

We report observations with the JWST/NIRCam coronagraph of the Fomalhaut system. This nearby A star hosts a complex debris disk system discovered by the IRAS satellite. Observation…

JWST-TST High Contrast: Achieving direct spectroscopy of faint substellar companions next to bright stars with the NIRSpec IFU

Jean-Baptiste Ruffio, Marshall D. Perrin, Kielan K. W. Hoch +33

The JWST NIRSpec integral field unit (IFU) presents a unique opportunity to observe directly imaged exoplanets from 3-5 um at moderate spectral resolution (R~2,700) and thereby bet…

JWST/NIRCam Coronagraphy of the Young Planet-hosting Debris Disk AU Microscopii

Kellen Lawson, Joshua E. Schlieder, Jarron M. Leisenring +20

High-contrast imaging of debris disk systems permits us to assess the composition and size distribution of circumstellar dust, to probe recent dynamical histories, and to directly…

Spatially resolved imaging of the inner Fomalhaut disk using JWST/MIRI

Andras Gaspar, Schuyler Grace Wolff, George H. Rieke +9

Planetary debris disks around other stars are analogous to the Asteroid and Kuiper belts in the Solar System. Their structure reveals the configuration of small bodies and provides…

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…

Hiding Dust Around Eridani

Schuyler G. Wolff, András Gáspár, George H. Rieke +2

With a Jupiter-like exoplanet and a debris disk with both asteroid and Kuiper belt analogs, Eridani has a fascinating resemblance to our expectations for a young Solar System.…

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…

Planet Search with the Keck/NIRC2 Vortex Coronagraph in Ms-band for Vega

Bin B. Ren, Nicole L. Wallack, Spencer A. Hurt +12

Gaps in circumstellar disks can signal the existence of planetary perturbers, making such systems preferred targets for direct imaging observations of exoplanets. Being one of the…
