The Hill sphere transits of Beta Pictoris c and the search for another 1981-like event

V. E. C. Bakker, M. A. Kenworthy, R. Stuik +17

Beta Pictoris is a young and nearby planetary system hosting an edge-on debris disk and at least three gas-giant planets. Their circumplanetary environments could host exomoons and…

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…

A second planetesimal collision in the Fomalhaut system

Paul Kalas, Jason J. Wang, Maxwell A. Millar-Blanchaer +7

The nearby star Fomalhaut is orbited by a compact source, Fomalhaut b, which has previously been interpreted as either a dust-enshrouded exoplanet or a dust cloud generated by the…

High Resolution ALMA Data of the Fomalhaut Debris Disk Confirms Apsidal Width Variation

Jay S. Chittidi, Meredith A. MacGregor, Joshua Bennett Lovell +11

We present long-baseline observations of the Fomalhaut outer debris disk at 223 GHz (1.3 mm) from ALMA Cycle 5, which we use along with archival short-baseline observations to prod…

HD 143811 AB b: A Directly Imaged Planet Orbiting a Spectroscopic Binary in Sco-Cen

Nathalie K. Jones, Jason J. Wang, Eric L. Nielsen +51

We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD…

Characterization of the Host Binary of the Directly Imaged Exoplanet HD 143811 AB b

Anne E. Peck, William Roberson, Eric L. Nielsen +50

HD~143811~AB is the host star to the directly imaged planet HD~143811~AB~b, which was recently discovered using data from the Gemini Planet Imager and Keck NIRC2. A member of the S…
