JWST-TST High Contrast: First Direct Spectroscopy of GJ 504 b reveals Clouds and Possible Metal Enrichment
Aneesh Baburaj, Jean-Baptiste Ruffio, Marshall Perrin +27
Characterizing the coldest directly imaged companions through direct spectroscopy has only recently become possible with the James Webb Space Telescope. We present moderate-resolut…
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…
The James Webb Space Telescope Mission: Optical Telescope Element Design, Development, and Performance
Michael W. McElwain, Lee D. Feinberg, Marshall D. Perrin +126
The James Webb Space Telescope (JWST) is a large, infrared space telescope that has recently started its science program which will enable breakthroughs in astrophysics and planeta…
James Webb Space Telescope Optical Simulation Testbed V: Wide-field phase retrieval assessment
Iva Laginja, Greg Brady, Remi Soummer +14
The James Webb Space Telescope (JWST) Optical Simulation Testbed (JOST) is a hardware simulator for wavefront sensing and control designed to produce JWST-like images. A model of t…
WFIRST-AFTA Coronagraphic Operations: Lessons Learned from the Hubble Space Telescope and the James Webb Space Telescope
John H. Debes, Marie Ygouf, Elodie Choquet +8
The coronagraphic instrument currently proposed for the WFIRST-AFTA mission will be the first example of a space-based coronagraph optimized for extremely high contrasts that are r…
James Webb Space Telescope Optical Simulation Testbed I: Overview and First Results
Marshall D. Perrin, Rémi Soummer, Élodie Choquet +13
The James Webb Space Telescope (JWST) Optical Simulation Testbed (JOST) is a tabletop workbench to study aspects of wavefront sensing and control for a segmented space telescope, i…
