A Candidate Innermost Fifth Planet In the HR 8799 System Revealed By JWST NIRISS Aperture Masking Interferometry

Jayke S. Nguyen, Louis Desdoigts, Alexandra Z. Greenbaum +20

We detect a candidate fifth planet in the HR 8799 system, directly imaged with the JWST/NIRISS Aperture Masking Interferometer (AMI). The detected source lies just above a con…

Direct Imaging Constraints on Binary Planets and Exomoons around Epsilon Indi A b

Matson Garza, Mary Anne Limbach, Rachel Bowens-Rubin +6

Epsilon Indi A b is a directly imaged exoplanet orbiting a nearby (3.6 pc) K-dwarf at AU. We analyze archival JWST/MIRI 15 m coronagraphic imaging…

Probing the Outskirts of M Dwarf Planetary Systems with a Cycle 1 JWST NIRCam Coronagraphy Survey

Ellis Bogat, Joshua E. Schlieder, Kellen D. Lawson +18

The population of giant planets on wide orbits around low-mass M dwarf stars is poorly understood, but the unprecedented sensitivity of JWST NIRCam coronagraphic imaging now provid…

JWST/NIRCam Detection of the Fomalhaut C Debris Disk in Scattered Light

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

Observations of debris disks offer important insights into the formation and evolution of planetary systems. Though M dwarfs make up approximately 80% of nearby stars, very few M-d…

The James Webb Interferometer: Space-based interferometric detections of PDS 70 b and c at 4.8 m

Dori Blakely, Doug Johnstone, Gabriele Cugno +22

We observed the planet-hosting system PDS 70 with the James Webb Interferometer, JWST's Aperture Masking Interferometric (AMI) mode within NIRISS. Observing with the F480M filter c…

MagAO-X and HST high-contrast imaging of the AS209 disk at H

Gabriele Cugno, Yifan Zhou, Thanawuth Thanathibodee +22

The detection of emission lines associated with accretion processes is a direct method for studying how and where gas giant planets form, how young planets interact with their nata…

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…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems II: A 1 to 20 Micron Spectrum of the Planetary-Mass Companion VHS 1256-1257 b

Brittany E. Miles, Beth A. Biller, Polychronis Patapis +101

We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a 20 M widely separated (8\arcsec, a = 150 au), young, planetary-…

The JWST Early Release Science Program for the Direct Imaging & Spectroscopy of Exoplanetary Systems

Sasha Hinkley, Aarynn L. Carter, Shrishmoy Ray +83

The direct characterization of exoplanetary systems with high contrast imaging is among the highest priorities for the broader exoplanet community. As large space missions will be…
