Multiband imaging of the HD 36546 debris disk: a refined view from SCExAO/CHARIS
Kellen Lawson, Thayne Currie, John P. Wisniewski +21
We present the first multi-wavelength (near-infrared; ) imaging of HD 36546's debris disk, using the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system co…
High-contrast integral field spectropolarimetry of planet-forming disks with SCExAO/CHARIS
Kellen Lawson, Thayne Currie, John P. Wisniewski +10
We describe a new high-contrast imaging capability well suited for studying planet-forming disks: near-infrared (NIR) high-contrast spectropolarimetric imaging with the Subaru Coro…
Implementation of a broadband focal plane estimator for high-contrast dark zones
Susan F. Redmond, Laurent Pueyo, Leonid Pogorelyuk +6
The characterization of exoplanet atmospheres using direct imaging spectroscopy requires high-contrast over a wide wavelength range. We study a recently proposed focal plane wavefr…
Flight mask designs of the Roman Space Telescope Coronagraph Instrument
A J Eldorado Riggs, Dwight Moody, Jessica Gersh-Range +17
Over the past two decades, thousands of confirmed exoplanets have been detected; the next major challenge is to characterize these other worlds and their stellar systems. Much info…
Information-theoretical Limits of Recursive Estimation and Closed-loop Control in High-contrast Imaging
Leonid Pogorelyuk, Laurent Pueyo, Jared R. Males +2
A lower bound on unbiased estimates of wavefront errors (WFE) is presented for the linear regime of small perturbation and active control of a high-contrast region (dark hole). Ana…
Exoplanet Detection in Starshade Images
Mengya, Hu, Anthony Harness +2
A starshade suppresses starlight by a factor of 1E11 in the image plane of a telescope, which is crucial for directly imaging Earth-like exoplanets. The state of the art in high co…
