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…
Resolving the terrestrial planet-forming region of HD 172555 with ALMA: I. Post-impact dust distribution
Zoe Roumeliotis, Luca MatrÃ, Grant M. Kennedy +5
Giant impacts between planetary embryos are a natural step in the terrestrial planet formation process and are expected to create disks of warm debris in the terrestrial regions of…
ALMA Reveals an Eccentricity Gradient in the Fomalhaut Debris Disk
Joshua B. Lovell, Elliot M. Lynch, Jay Chittidi +6
We present evidence of a negative eccentricity gradient in the debris disk of the nearby A-type main sequence star, Fomalhaut. Fitting to the high-resolution, archival ALMA 1.32 mm…
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…
The HOSTS Survey: Suspected variable dust emission and constraints on companions around θ Boo
G. Garreau, D. Defrère, S. Ertel +23
During the HOSTS survey by the LBTI, an excess emission from the main sequence star θ Boo (F7V spectral type, 14.5pc distance) was observed. This excess indicates the presence of…
