Breaking the brightness barrier: JWST/NIRCam DHS spectroscopy for high-precision time-series observations
Achrene Dyrek, John Stansberry, Louis E. Bergeron +12
Many of the most scientifically compelling exoplanets orbit bright nearby stars that exceed the brightness limits of existing JWST spectroscopic observing modes. To address this li…
Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
We report the direct imaging discovery of a third exoplanet in the Pictoris system. We detect Pictoris d ( Pic d) in non-coronagraphic observations obtained with VLT/ERI…
Direct Images of CO2 Absorption in the Atmosphere of a Super-Jupiter: Enhanced Metallicity Suggestive of Formation in a Disk
William O. Balmer, Laurent Pueyo, Ashley Messier +15
It is unclear how directly imaged substellar companions with masses near the deuterium burning limit form, because these objects are rare and their bulk properties are not diagnost…
A second visit to Eps Ind Ab with JWST: new photometry confirms ammonia and suggests thick clouds in the exoplanet atmosphere of the closest super-Jupiter
Elisabeth C. Matthews, James Mang, Aarynn L. Carter +9
With JWST, we are directly imaging cold (~200-300K), solar-age giant exoplanets for the first time. At these temperatures many molecular features appear and water-ice clouds may co…
Worlds Next Door. IV. Mapping the Late Stages of Giant Planet Evolution with a Precise Dynamical Mass and Luminosity for Ind Ab
Aniket Sanghi, William Thompson, James Mang +21
We present new JWST/NIRCam 4-5 m (F410M, F430M) and JWST/MIRI 18-25 m (F1800W, F2100W, F2550W) imaging detections of the nearby (3.6 pc) cold (275 K) gas giant exoplanet …
Empirical Modeling of Zodiacal Backgrounds to Improve JWST NIRISS/SOSS Data Reduction
Tyler Baines, Aarynn Carter, Néstor Espinoza +3
Zodiacal light -- arising from both the thermal emission and scattered sunlight by interplanetary dust -- is the dominant component of the sky background in NIRISS Single Object Sl…
Effects of Jump Detection and Ramp Fitting Algorithms on NIRISS/SOSS Exoplanet Time-Series Observations
Aarynn Carter, Néstor Espinoza, Loïc Albert +4
Jump detection and ramp fitting are fundamental steps when elevating JWST data products from up-the-ramp measurements to integration level count rate images. Occurring at an early…
The Effects of Binary Reference Stars on JWST NIRCam Coronagraphy
Klaus Subbotina Stephenson, Aarynn Carter, Andrew Skemer
Direct imaging campaigns executed with James Webb Space Telescope (JWST) will enable the study of the faintest observable exoplanets yet. To assist observers in the JWST proposal p…
