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…
Trends in Silicates in the Pictoris Disk
Cicero X. Lu, Christine H. Chen, B. A. Sargent +14
While beta Pic is known to host silicates in ring-like structures, whether the properties of these silicate dust vary with stellocentric distance remains an open question. We re-an…
A Multi-Wavelength Study of the Highly Asymmetrical Debris Disk Around HD 111520
Katie A. Crotts, Zachary H. Draper, Brenda C. Matthews +7
We observed the nearly edge-on debris disk system HD 111520 at , , & near infrared (NIR) bands using both the spectral and polarization modes of the Gemini Planet Imager…
The JWST Early Release Science Program for the Direct Imaging & Spectroscopy of Exoplanetary Systems
Sasha Hinkley, Aarynn L. Carter, Shrishmoy Ray +83
The direct characterization of exoplanetary systems with high contrast imaging is among the highest priorities for the broader exoplanet community. As large space missions will be…
A highly settled disk around Oph 163131
M. Villenave, K. R. Stapelfeldt, G. Duchene +10
High dust density in the midplane of protoplanetary disks is favorable for efficient grain growth and can allow fast formation of planetesimals and planets, before disks dissipate.…
