A Uniform Analysis of Debris Disks with the Gemini Planet Imager I: An Empirical Search for Perturbations from Planetary Companions in Polarized Light Images
Katie A. Crotts, Brenda C. Matthews, Gaspard Duchêne +37
The Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-infrared. The GPI Exoplanet Survey (GPIES) imaged twenty-four debris disks in polarized -band lig…
JWST-TST High Contrast: Achieving direct spectroscopy of faint substellar companions next to bright stars with the NIRSpec IFU
Jean-Baptiste Ruffio, Marshall D. Perrin, Kielan K. W. Hoch +33
The JWST NIRSpec integral field unit (IFU) presents a unique opportunity to observe directly imaged exoplanets from 3-5 um at moderate spectral resolution (R~2,700) and thereby bet…
Stirred but not shaken: a multi-wavelength view of HD 16743's debris disc
Jonathan P. Marshall, Julien Milli, Elodie Choquet +6
Planetesimals -- asteroids and comets -- are the building blocks of planets in protoplanetary discs and the source of dust, ice and gas in debris discs. Along with planets they com…
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…
Debris Disk Color with the Hubble Space Telescope
Bin B. Ren, Isabel Rebollido, Élodie Choquet +14
Multi-wavelength scattered light imaging of debris disks may inform dust properties including typical size and mineral composition. Existing studies have investigated a small set o…
Low-order wavefront control using a Zernike sensor through Lyot coronagraphs for exoplanet imaging: II. Concurrent operation with stroke minimization
R. Pourcelot, E. H. Por, M. N'Diaye +16
Wavefront sensing and control (WFSC) will play a key role in improving the stability of future large segmented space telescopes while relaxing the thermo-mechanical constraints on…
