Modeling Polarization Signals from Cloudy Brown Dwarfs: Luhman 16 A and B in Three Dimensions
Sagnick Mukherjee, Jonathan J. Fortney, Rebecca Jensen-Clem +3
The detection of disk-integrated polarization from Luhman 16A and B in H-band, and subsequent modeling, has been interpreted in the framework of zonal cloud bands on these bodies.…
Precise Masses and Orbits for Nine Radial Velocity Exoplanets
Yiting Li, Timothy D. Brandt, G. Mirek Brandt +6
Radial velocity (RV) surveys have discovered hundreds of exoplanetary systems but suffer from a fundamental degeneracy between planet mass and orbital inclination . In thi…
The Planetary Systems Imager Adaptive Optics System: An Initial Optical Design and Performance Analysis Tools for the PSI-Red AO System
Rebecca Jensen-Clem, Philip M. Hinz, M. A. M. van Kooten +10
The Planetary Systems Imager (PSI) is a proposed instrument for the Thirty Meter Telescope (TMT) that provides an extreme adaptive optics (AO) correction to a multi-wavelength inst…
The Santa Cruz Extreme AO Lab (SEAL): Design and First Light
Rebecca Jensen-Clem, Daren Dillon, Benjamin Gerard +9
The Santa Cruz Extreme AO Lab (SEAL) is a new visible-wavelength testbed designed to advance the state of the art in wavefront control for high contrast imaging on large, segmented…
First Experimental Results of the Fast Atmospheric Self-coherent Camera Technique on the Santa cruz Extreme Adaptive optics Laboratory Testbed: Demonstration of High Speed Focal Plane Wavefront Control of Residual Atmospheric Speckles
Benjamin L. Gerard, Daren Dillon, Sylvain Cetre +3
Current and future high contrast imaging instruments aim to detect exoplanets at closer orbital separations, lower masses, and/or older ages than their predecessors, with the event…
Status of predictive wavefront control on Keck II adaptive optics bench: on-sky coronagraphic results
Maaike A. M. van Kooten, Rebecca Jensen-Clem, Sylvain Cetre +4
The behavior of an adaptive optics (AO) system for ground-based high contrast imaging (HCI) dictates the achievable contrast of the instrument. In conditions where the coherence ti…
The Bright Pyramid Wavefront Sensor
Benjamin L. Gerard, Vincent Chambouleyron, Rebecca Jensen-Clem +1
Extreme adaptive optics (AO) is crucial for enabling the contrasts needed for ground-based high contrast imaging instruments to detect exoplanets. Pushing exoplanet imaging detecti…
Guest Editorial: Overview of the Special Issue and a Dialog on Starshades
Jonathan Arenberg, Anthony Harness, Rebecca Jensen-Clem
This special issue is dedicated to starshades: science, engineering, technology and programmatics. Our reasons for organizing this special issue are several fold. First as a new te…
Large Adaptive Optics Survey for Substellar Objects (LASSO) Around Young, Nearby, Low-mass Stars with Robo-AO
Maissa Salama, James Ou, Christoph Baranec +16
We present results from the Large Adaptive optics Survey for Substellar Objects (LASSO), where the goal is to directly image new substellar companions (<70 M) at wide orbit…
Exoplanet Imaging Data Challenge: benchmarking the various image processing methods for exoplanet detection
F. Cantalloube, C. Gomez-Gonzalez, O. Absil +23
The Exoplanet Imaging Data Challenge is a community-wide effort meant to offer a platform for a fair and common comparison of image processing methods designed for exoplanet direct…
A survey of the linear polarization of directly imaged exoplanets and brown dwarf companions with SPHERE-IRDIS. First polarimetric detections revealing disks around DH Tau B and GSC 6214-210 B
R. G. van Holstein, T. Stolker, R. Jensen-Clem +22
Young giant planets and brown dwarf companions emit near-infrared radiation that can be linearly polarized up to several percent. This polarization can reveal the presence of a cir…
