Roman coronagraph simulations of exozodi observations in the presence of wavefront errors
Jorge Llop-Sayson, Vanessa P. Bailey, Justin Hom +6
The Coronagraph Instrument on board of the Nancy Grace Roman Space Telescope will demonstrate key technologies that will prepare the ground for the Habitable Worlds Observatory. Th…
JWST/MIRI Imaging of the Warm Dust Component of the Epsilon Eridani Debris Disk
Schuyler G. Wolff, András Gáspár, George Rieke +4
We present JWST/MIRI observations of the debris disk surrounding the nearby, solar analog Epsilon Eridani obtained as part of the Archetypal Debris Disk GTO program. Multi-waveleng…
Wavefront Error Recovery and Companion Identification with the James Webb Space Telescope
Matthew De Furio, Marie Ygouf, Alexandra Greenbaum +8
The James Webb Space Telescope is orders of magnitude more sensitive than any other facility across the near to mid-infrared wavelengths. Many approved programs take advantage of i…
Searching for Planets Orbiting ~Eridani with JWST/NIRCam
Jorge Llop-Sayson, Charles Beichman, Geoffrey Bryden +10
We present observations of \epseri~with the JWST/NIRCam coronagraph aimed at imaging planets orbiting within this system. In particular, these observations targeted (1) the Jupiter…
Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of Cen A. I. Observations, Orbital and Physical Properties, and Exozodi Upper Limits
Charles Beichman, Aniket Sanghi, Dimitri Mawet +27
We report on coronagraphic observations of the nearest solar-type star, Cen A, using the MIRI instrument on the James Webb Space Telescope. With three epochs of observation (Au…
Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of Cen A. II. Binary Star Modeling, Planet and Exozodi Search, and Sensitivity Analysis
Aniket Sanghi, Charles Beichman, Dimitri Mawet +14
JWST observed our closest solar twin, Cen A, with the MIRI coronagraph in F1550C (15.5 m) at three distinct epochs between August 2024 and April 2025. For the first time wit…
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-TST High Contrast: Living on the Wedge, or, NIRCam Bar Coronagraphy Reveals CO in the HR 8799 and 51 Eri Exoplanets' Atmospheres
William O. Balmer, Jens Kammerer, Laurent Pueyo +19
High-contrast observations with JWST can reveal key composition and vertical mixing dependent absorption features in the spectra of directly imaged planets across the 3-5 m wave…
