The grazing angle icy protoplanetary disk PDS 453

Laurine Martinien, François Ménard, Gaspard Duchêne +12

PDS 453 is a rare highly inclined disk where the stellar photosphere is seen at grazing incidence on the disk surface. Our goal is take advantage of this geometry to constrain the…

The apparent absence of forward scattering in the HD 53143 debris disk

Christopher C. Stark, Bin Ren, Meredith A. MacGregor +5

HD 53143 is a mature Sun-like star and host to a broad disk of dusty debris, including a cold outer ring of planetesimals near 90 AU. Unlike most other inclined debris disks imaged…

Debris Disk Color with the Hubble Space Telescope

Bin B. Ren, Isabel Rebollido, Élodie Choquet +14

Multi-wavelength scattered light imaging of debris disks may inform dust properties including typical size and mineral composition. Existing studies have investigated a small set o…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems II: A 1 to 20 Micron Spectrum of the Planetary-Mass Companion VHS 1256-1257 b

Brittany E. Miles, Beth A. Biller, Polychronis Patapis +101

We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a 20 M widely separated (8\arcsec, a = 150 au), young, planetary-…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems I: High Contrast Imaging of the Exoplanet HIP 65426 b from 2-16 m

Aarynn L. Carter, Sasha Hinkley, Jens Kammerer +108

We present JWST Early Release Science (ERS) coronagraphic observations of the super-Jupiter exoplanet, HIP 65426 b, with the Near-Infrared Camera (NIRCam) from 2-5 m, and with t…

ALMA Images the Eccentric HD 53143 Debris Disk

Meredith A. MacGregor, Spencer A. Hurt, Christopher C. Stark +6

We present ALMA 1.3 mm observations of the HD~53143 debris disk - the first infrared or millimeter image produced of this ~1 Gyr-old solar-analogue. Previous HST STIS coronagraphic…
