How eccentric is the debris disk of epsilon Eridani? ALMA reveals a near-circular belt

Oto Ulrich, Joshua B. Lovell, David J. Wilner +2

The nearby (3.2 pc) K2V star Eridani hosts the closest detected debris disk and an exo-Jupiter analog ( Eridani b). In this work, we reanalyse ALMA Band 6 (1.29 mm) observat…

Discovery of a Debris Disk Around TWA 20

Skyler Palatnick, Maxwell A. Millar-Blanchaer, Jingwen Zhang +20

We report the discovery of a debris disk surrounding the M3 star, TWA 20, revealed by JWST coronagraphic observations using the Near-infrared Camera (NIRCam). With reference-star d…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems V: Do Self-Consistent Atmospheric Models Represent JWST Spectra? A Showcase With VHS 1256 b

Simon Petrus, Niall Whiteford, Polychronis Patapis +119

The unprecedented medium-resolution (R~1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (140+/-20Myr) low-mass (12-20MJup) L-T transition (L7) com…

The effect of sculpting planets on the steepness of debris-disc inner edges

Tim D. Pearce, Alexander V. Krivov, Antranik A. Sefilian +6

Debris discs are our best means to probe the outer regions of planetary systems. Many studies assume that planets lie at the inner edges of debris discs, akin to Neptune and the Ku…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems IV: NIRISS Aperture Masking Interferometry Performance and Lessons Learned

Steph Sallum, Shrishmoy Ray, Jens Kammerer +120

We present a performance analysis for the aperture masking interferometry (AMI) mode on board the James Webb Space Telescope Near Infrared Imager and Slitless Spectrograph (JWST/NI…
