Characterizing microlensing planetary system OGLE-2014-BLG-0676Lb with adaptive optics imaging
Xiao-Jia Xie, Subo Dong, Yossi Shvartzvald +10
We constrain the host-star flux of the microlensing planet OGLE-2014-BLG-0676Lb using adaptive optics (AO) images taken by the Magellan and Keck telescopes. We measure the flux of…
MagAO observations of the binary microlens OGLE-2014-BLG-1050 prefer the higher-mass solution
Xiaojia Xie, Subo Dong, Wei Zhu +9
We report adaptive-optics (AO) follow-up imaging of OGLE-2014-BLG-1050, which is the second binary microlensing event with space-based parallax measurements. The degeneracy in micr…
Design of the vacuum high contrast imaging testbed for CDEEP, the Coronagraphic Debris and Exoplanet Exploring Pioneer
Erin R. Maier, Ewan S. Douglas, Daewook Kim +26
The Coronagraphic Debris Exoplanet Exploring Payload (CDEEP) is a Small-Sat mission concept for high contrast imaging of circumstellar disks. CDEEP is designed to observe disks in…
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…
Imaging low-mass planets within the habitable zones of nearby stars with ground-based mid-infrared imaging
Kevin Wagner, Steve Ertel, Jordan Stone +8
Giant exoplanets on 10-100 au orbits have been directly imaged around young stars. The peak of the thermal emission from these warm young planets is in the near-infrared (~1-5 micr…
Characterizing deformable mirrors for the MagAO-X instrument
Kyle Van Gorkom, Jared R. Males, Laird M. Close +11
The MagAO-X instrument is a new extreme adaptive optics system for high-contrast imaging at visible and near-infrared wavelengths on the Magellan Clay Telescope. A central componen…
The Mysterious Lives Of Speckles. I. Residual atmospheric speckle lifetimes in ground-based coronagraphs
Jared R. Males, Michael P. Fitzgerald, Ruslan Belikov +1
High-contrast imaging observations are fundamentally limited by the spatially and temporally correlated noise source called speckles. Suppression of speckle noise is the key goal o…
Millisecond Exoplanet Imaging, I: Method and Simulation Results
Alexander T Rodack, Richard A Frazin, Jared R Males +1
One of the top remaining science challenges in astronomical optics is the direct imaging and characterization of extrasolar planets and planetary systems. Directly imaging exoplane…
High-contrast observations of brown dwarf companion HR 2562 B with the vector Apodizing Phase Plate coronagraph
Ben J. Sutlieff, Alexander J. Bohn, Jayne L. Birkby +8
The vector Apodizing Phase Plate (vAPP) is a class of pupil plane coronagraph that enables high-contrast imaging by modifying the Point Spread Function (PSF) to create a dark hole…
The vector-apodizing phase plate coronagraph: design, current performance, and future development
D. S. Doelman, F. Snik, E. H. Por +50
Over the last decade, the vector-apodizing phase plate (vAPP) coronagraph has been developed from concept to on-sky application in many high-contrast imaging systems on 8-m class t…
Data-driven subspace predictive control of adaptive optics for high-contrast imaging
Sebastiaan Y. Haffert, Jared R. Males, Laird M. Close +11
The search for exoplanets is pushing adaptive optics systems on ground-based telescopes to their limits. One of the major limitations at small angular separations, exactly where ex…
The HOSTS survey: evidence for an extended dust disk and constraints on the presence of giant planets in the Habitable Zone of Leo
D. Defrère, P. M. Hinz, G. M. Kennedy +38
The young (50-400 Myr) A3V star Leo is a primary target to study the formation history and evolution of extrasolar planetary systems as one of the few stars with known hot ($\s…
Unlocking starlight subtraction in full data rate exoplanet imaging by efficiently updating Karhunen-Loève eigenimages
Joseph D. Long, Jared R. Males
Starlight subtraction algorithms based on the method of Karhunen-Loève eigenimages have proved invaluable to exoplanet direct imaging. However, they scale poorly in runtime when pa…
An innovative integral field unit upgrade with 3D-printed micro-lenses for the RHEA at Subaru
Theodoros Anagnos, Pascal Maier, Philipp Hottinger +26
In the new era of Extremely Large Telescopes (ELTs) currently under construction, challenging requirements drive spectrograph designs towards techniques that efficiently use a faci…
