A Misaligned Debris Disk relative to the Host Star CPD-72 2713 from JWST/NIRCam Imaging
Jingwen Zhang, Maxwell A. Millar-Blanchaer, Kellen Lawson +17
Observations of debris disks provide a valuable window to investigate the formation and evolution of planetary systems. We present high-contrast JWST/NIRCam observations of CPD-72…
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…
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…
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…
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…
The Companions to B and A Stars Snapshot (C-BASS) Survey: I. Discovery of a Young Brown Dwarf Companion to HIP 17453
Marah Brinjikji, Adam J. Smith, Jennifer Patience +26
We report the detection of a new brown dwarf companion to HIP 17453 A, a chemically peculiar A0V star located at a distance of 81 pc. HIP 17453 A was observed with high-resolution…
Discovery of an Exterior Third Planet Orbiting Pictoris
Aidan Gibbs, Jean-Baptiste Ruffio, Alexis Bidot +9
We report the discovery of Pictoris d ( Pic d), a third giant planet in the Pictoris system, which now becomes only the second directly imaged system with more than two…
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…
