High-contrast imager for complex aperture telescopes (HiCAT): 8. Dark zone demonstration with simultaneous closed-loop low-order wavefront sensing and control

Rémi Soummer, Emiel H. Por, Raphaël Pourcelot +27

We present recent laboratory results demonstrating high-contrast coronagraphy for the future space-based large IR/Optical/Ultraviolet telescope recommended by the Decadal Survey. T…

Crowded No More: The Accuracy of the Hubble Constant Tested with High Resolution Observations of Cepheids by JWST

Adam G. Riess, Gagandeep S. Anand, Wenlong Yuan +7

High-resolution JWST observations can test confusion-limited HST observations for a photometric bias that could affect extragalactic Cepheids and the determination of the Hubble co…

A Year of Wavefront Sensing with JWST in Flight: Cycle 1 Telescope Monitoring and Maintenance Summary

Charles-Philippe Lajoie, Matthew Lallo, Marcio Meléndez +7

We summarize JWST's measured telescope performance across science Cycle 1. The stability of segments alignments is typically better than 10 nanometers RMS between measurements ever…

JWST-TST Proper Motions: I. High-Precision NIRISS Calibration and Large Magellanic Cloud Kinematics

M. Libralato, A. Bellini, R. P. van der Marel +27

We develop and disseminate effective point-spread functions and geometric-distortion solutions for high-precision astrometry and photometry with the JWST NIRISS instrument. We corr…

Demographics of Protoplanetary Disks: A Simulated Population of Edge-on Systems

Isabel Angelo, Gaspard Duchêne, Karl Stapelfeldt +9

The structure of protoplanetary disks plays an essential role in planet formation. Disks that are highly inclined, or ''edge-on'', are of particular interest since their geometry p…

Testing the Interaction Between a Substellar Companion and a Debris Disk in the HR 2562 System

Stella Yimiao Zhang, Gaspard Duchêne, Robert J. De Rosa +51

The HR 2562 system is a rare case where a brown dwarf companion resides in a cleared inner hole of a debris disk, offering invaluable opportunities to study the dynamical interacti…
