Direct imaging of an asymmetric debris disk in the HD 106906 planetary system
Paul G. Kalas, Abhijith Rajan, Jason J. Wang +53
We present the first scattered light detections of the HD 106906 debris disk using Gemini/GPI in the infrared and HST/ACS in the optical. HD 106906 is a 13 Myr old F5V star in the…
Searching for Planets Orbiting Fomalhaut with JWST/NIRCam
Marie Ygouf, Charles Beichman, Jorge Llop-Sayson +20
We report observations with the JWST/NIRCam coronagraph of the Fomalhaut system. This nearby A star hosts a complex debris disk system discovered by the IRAS satellite. Observation…
The Near Infrared Imager and Slitless Spectrograph for JWST -- V. Kernel Phase Imaging and Data Analysis
Jens Kammerer, Rachel A. Cooper, Thomas Vandal +26
Kernel phase imaging (KPI) enables the direct detection of substellar companions and circumstellar dust close to and below the classical (Rayleigh) diffraction limit. We present a…
Wavefront Error Recovery and Companion Identification with the James Webb Space Telescope
Matthew De Furio, Marie Ygouf, Alexandra Greenbaum +8
The James Webb Space Telescope is orders of magnitude more sensitive than any other facility across the near to mid-infrared wavelengths. Many approved programs take advantage of i…
Searching for Planets Orbiting Vega with the James Webb Space Telescope
Charles Beichman, Geoffrey Bryden, Jorge Llop-Sayson +15
The most prominent of the IRAS debris disk systems, Lyrae (Vega), at a distance of 7.7 pc, has been observed by both the NIRCam and MIRI instruments on the James Webb Space Te…
CD-27 11535: Evidence for a Triple System in the Pictoris Moving Group
Andrew D. Thomas, Eric L. Nielsen, Robert J. De Rosa +20
We present new spatially resolved astrometry and photometry of the CD-27 11535 system, a member of the Pictoris moving group consisting of two resolved K-type stars on a $\sim…
Kernel-phase Detection Limits : Hypothesis Testing and the Example of JWST NIRISS Full Pupil Images
Alban Ceau, David Mary, Alexandra Greenbaum +4
The James Webb Space Telescope will offer high-angular resolution observing capability in the near-infrared with masking interferometry on NIRISS, and coronagraphic imaging on NIRC…
The Palomar Kernel Phase Experiment: Testing Kernel Phase Interferometry for Ground-based Astronomical Observations
Benjamin Pope, Peter Tuthill, Sasha Hinkley +5
At present, the principal limitation on the resolution and contrast of astronomical imaging instruments comes from aberrations in the optical path, which may be imposed by the Eart…
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…
In-focus wavefront sensing using non-redundant mask-induced pupil diversity
Alexandra Greenbaum, Anand Sivaramakrishnan
Wavefront estimation using in-focus image data is critical to many applications. This data is invariant to a sign flip with complex conjugation of the complex amplitude in the pupi…
First Scattered-Light Image of the Debris Disk around HD 131835 with the Gemini Planet Imager
Li-Wei Hung, Gaspard Duchêne, Pauline Arriaga +34
We present the first scattered-light image of the debris disk around HD 131835 in band using the Gemini Planet Imager. HD 131835 is a 15 Myr old A2IV star at a distance o…
A Search for Intermediate Separation Low Mass Binaries in the Orion Nebula Cluster
Matthew De Furio, Megan Reiter, Michael Meyer +3
We present the results of a binary population study in the Orion Nebula Cluster (ONC) using archival Hubble Space Telescope (HST) data obtained with the Advanced Camera for Surveys…
Observing Outer Planet Satellites (except Titan) with JWST: Science Justification and Observational Requirements
Laszlo Keszthelyi, Will Grundy, John Stansberry +6
The James Webb Space Telescope (JWST) will allow observations with a unique combination of spectral, spatial, and temporal resolution for the study of outer planet satellites withi…
Current laboratory performance of starlight suppression systems, and potential pathways to desired Habitable Worlds Observatory exoplanet science capabilities
Bertrand Mennesson, Ruslan Belikov, Emiel Por +34
We summarize the current best polychromatic (10 to 20 % bandwidth) contrast performance demonstrated in the laboratory by different starlight suppression approaches and systems des…
Automated data processing architecture for the Gemini Planet Imager Exoplanet Survey
Jason Wang, Marshall Perrin, Dmitry Savransky +49
The Gemini Planet Imager Exoplanet Survey (GPIES) is a multi-year direct imaging survey of 600 stars to discover and characterize young Jovian exoplanets and their environments. We…
