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…
