The Science Potential of Characterizing Gas Giant Exoplanets with HWO
Beck Dacus, Jean-Baptiste Ruffio, Quinn Konopacky +19
With the ability to directly image Earth-like exoplanets and search their atmospheres for biosignatures, the upcoming Habitable Worlds Observatory (HWO) will also collect high sign…
The JWST Sub-Jupiters Survey: Direct Imaging Discovery of a Giant Planet and a Debris Disk Around the Young M-dwarf RX J0534.0-0221
Rodrigo Ferrer-Chavez, Jason J. Wang, Kevin Wagner +47
We present the discovery of RX J0534.0-0221 b, a giant planet orbiting an M-dwarf star in the Pictoris moving group. RX J0534 was originally observed with JWST/NIRCam in the F4…
The Dyn-Atmo Survey: JWST/NIRSpec spectroscopy of dynamical benchmark GJ 758 B
Alexander Madurowicz, Emily Rickman, Daniella Bardalez Gagliuffi +22
We present new JWST/NIRSpec IFU high contrast spectroscopic observations of the brown dwarf companion GJ 758 B. Extensive radial velocity monitoring of the primary has enabled high…
The Dyn-Atmo Survey: High-contrast Imaging Spectroscopy of the Substellar Companion HD 13724 B with the JWST NIRSpec IFU
Kielan K. W. Hoch, Alex Madurowicz, Evert Nasedkin +22
We present the first spectral analysis from the JWST Cycle 3 GO Program #6362, the Dyn-Atmo Survey of dynamical-atmospheric benchmarks, characterizing the atmospheres of directly-i…
Impacts of Correlated Noise on Retrievals of Exo-Earth Atmospheres
Nicole Wolff, Bruce Macintosh, Tyler D. Robinson +6
The Habitable Worlds Observatory (HWO) aims to accomplish high-contrast imaging and spectroscopy of true Earth analogs for the first time. However, high-contrast spectroscopy with…
The Roman Coronagraph Community Participation Program: early calibration plan and pilot observation of a companion
Julien H. Girard, Eric Cady, Neil T. Zimmerman +42
Roman is set to launch in weeks! The Coronagraph Instrument - technology pathfinder for future direct imaging missions - is ready to fly too. According to predictions, laboratory t…
A Sulfur-Rich Atmosphere for the Young Jupiter Analog AF Lep b Reveals Significant Solid Accretion
Jerry W. Xuan, William O. Balmer, Yayaati Chachan +25
AF Lep b is one of the closest analogs to Jupiter in terms of mass () and semi-major axis ( AU) amenable to spectroscopic characterization. We present JWST/NIR…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems VIII: patchy forsterite and enstatite clouds in the atmosphere of VHS 1256 b, retrieval lessons learned and outlook to the future
Niall Whiteford, Jacqueline K. Faherty, Ben Burningham +123
JWST defines a new era for the data-driven approach of retrieval modelling, which has become a cornerstone tool for the statistical inference of exoplanetary and brown dwarf proper…
Photometric Variability and Rotation of Beta Pictoris b from JWST NIRCam Coronagraphic Imaging
Yifan Zhou, Beth A. Biller, Aarynn L. Carter +28
We report the detection of photometric variability in the directly imaged super-Jupiter Pictoris b. Using JWST NIRCam dual-band coronagraphic imaging, we conducted a 16-hour co…
Characterizing Earth analogs may require a moderate or high-resolution spectrograph
Jean-Baptiste Ruffio, Sarah Steiger, Corey Spohn +16
A primary goal of the Habitable Worlds Observatory (HWO) is to detect and measure the abundance of biosignature molecules, such as water (H2O) and oxygen (O2), in the atmosphere of…
Habitable World Discovery and Characterization: Coronagraph Concept of Operations and Data Post-Processing
Michael W. McElwain, Dimitri Mawet, Jean-Baptiste Ruffio +11
The discovery and characterization of habitable worlds was the top scientific recommendation of the Astro2020 decadal survey and is a key objective of the Habitable Worlds Observat…
Cross-Model Validation of Coronagraphic Exposure Time Calculators for the Habitable Worlds Observatory: A Report from the Exoplanet Science Yield sub-Working Group
Christopher C. Stark, Sarah Steiger, Armen Tokadjian +9
Estimating the exoplanet scientific productivity of the Habitable Worlds Observatory requires estimating science exposure times. From exoplanet yields to spectral retrievals, expos…
The Roman coronagraph community participation program: observation planning
Schuyler G. Wolff, Jason Wang, Karl Stapelfeldt +18
The Coronagraphic Instrument onboard the Nancy Grace Roman Space Telescope is an important stepping stone towards the characterization of habitable, rocky exoplanets. In a technolo…
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…
Coronagraphic Data Post-processing Using Projections on Instrumental Modes
Yinzi Xin, Laurent Pueyo, Romain Laugier +4
Directly observing exoplanets with coronagraphs is impeded by the presence of speckles from aberrations in the optical path, which can be mitigated in hardware with wavefront contr…
