Astrometric Evidence for Outer Giant Planets in Known Exoplanet Systems
Clarissa R. Do Ó, William Thompson, Dori Blakely +19
Outer giant planets can influence the formation and dynamical evolution of their planetary systems. However, their long orbital periods make them difficult to detect using transit…
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…
Time-variable Scattered Light in Herbig Disks Observed with Subaru/SCExAO
Camryn Mullin, Miles Lucas, Ruobing Dong +12
Using the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument, we present near-infrared K-band polarimetric imaging of nine Herbig stars selected from a volume-limited…
Dynamical Mass Constraints on Transition Disk Perturbers with the G23H Catalog
Dori Blakely, William Thompson, Doug Johnstone +14
We present dynamical mass constraints on perturbers in 11 transition disk systems using a novel combination of calibrated Hipparcos and Gaia absolute astrometry data. Out of the sa…
Detecting and Characterizing Companions with a Calibrated Gaia DR2, DR3, and Hipparcos Catalog (G23H)
William Thompson, Dori Blakely, Jerry W. Xuan +16
Gaia DR4 epoch astrometry will enable the detection of thousands of exoplanets through astrometric motion. Here, we present a composite catalog and modeling framework that extracts…
Image reconstruction with the JWST Interferometer
Max Charles, Louis Desdoigts, Benjamin Pope +7
Flying on board the James Webb Space Telescope (JWST) above Earth's turbulent atmosphere, the Aperture Masking Interferometer (AMI) on the NIRISS instrument is the highest-resoluti…
AMIGO: a Data-Driven Calibration of the JWST Interferometer
Louis Desdoigts, Benjamin Pope, Max Charles +8
The James Webb Space Telescope (JWST) hosts a non-redundant Aperture Masking Interferometer (AMI) in its Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument, providi…
A Tentative Detection of a Point Source in the Disk Gap of HD 100546 with VLT/SPHERE-IRDIS Sparse Aperture Masking Interferometry
Dori Blakely, Doug Johnstone, Tomas Stolker +5
We re-analyze VLT/SPHERE-IRDIS K and H-band sparse aperture masking interferometry data of the transition disk HD 100546 observed in 2018 and 2021, respectively. We fit geometrical…
On the Orbit of the Binary Brown Dwarf Companion GL229 Ba and Bb
William Thompson, Dori Blakely, Jerry W. Xuan +21
The companion GL229B was recently resolved by Xuan et al. (2024) as a tight binary of two brown dwarfs (Ba and Bb) through VLTI-GRAVITY interferometry and VLT-CRIRES+ RV measuremen…
The James Webb Interferometer: Space-based interferometric detections of PDS 70 b and c at 4.8 m
Dori Blakely, Doug Johnstone, Gabriele Cugno +22
We observed the planet-hosting system PDS 70 with the James Webb Interferometer, JWST's Aperture Masking Interferometric (AMI) mode within NIRISS. Observing with the F480M filter c…
Searching for low-mass companions at small separations in transition disks with aperture masking interferometry
Tomas Stolker, Jens Kammerer, Myriam Benisty +9
Transition disks have large central cavities that have been spatially resolved during recent years. Cavities and other substructures in circumstellar disks are often interpreted as…
