A Candidate Innermost Fifth Planet In the HR 8799 System Revealed By JWST NIRISS Aperture Masking Interferometry
Jayke S. Nguyen, Louis Desdoigts, Alexandra Z. Greenbaum +20
We detect a candidate fifth planet in the HR 8799 system, directly imaged with the JWST/NIRISS Aperture Masking Interferometer (AMI). The detected source lies just above a con…
orbitize! v3: Orbit fitting for the High-contrast Imaging Community
Sarah Blunt, Jason Jinfei Wang, Lea Hirsch +18
orbitize! is a package for Bayesian modeling of the orbital parameters of resolved binary objects from time series measurements. It was developed with the needs of the high-contras…
Radial Velocity and Astrometric Evidence for a Close Companion to Betelgeuse
Morgan MacLeod, Sarah Blunt, Robert J. De Rosa +10
We examine a century of radial velocity, visual magnitude, and astrometric observations of the nearest red supergiant, Betelgeuse, in order to reexamine the century-old assertion t…
Analyzing the Atmospheric Dispersion Correction of the Gemini Planet Imager: residual dispersion above design requirements
Malachi Noel, Jason J. Wang, Bruce Macintosh +6
The Atmospheric Dispersion Corrector (ADC) of the Gemini Planet Imager (GPI) corrects the chromatic dispersion caused by differential atmospheric refraction (DAR), making it an imp…
A Uniform Analysis of Debris Disks with the Gemini Planet Imager II: Constraints on Dust Density Distribution Using Empirically-Informed Scattering Phase Functions
Justin Hom, Jennifer Patience, Christine H. Chen +40
Spatially-resolved images of debris disks are necessary to determine disk morphological properties and the scattering phase function (SPF) which quantifies the brightness of scatte…
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 …
