SHIMM as an atmospheric profiler on the Nickel Telescope
Ollie Jackson, Maaike A. M. van Kooten, Saavidra Perera +2
Optimal atmospheric conditions are beneficial for detecting exoplanets via high contrast imaging (HCI), as speckles from adaptive optics' (AO's) residuals can make it difficult to…
The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES): driving science cases and expected outcomes
Steph Sallum, Andrew Skemer, Deno Stelter +34
The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES) is a m, high-contrast integral field spectrograph (IFS) currently being built for Keck Observa…
Closed-Loop Until Further Notice: Comparing Predictive Control Methods in Closed-Loop
J. Fowler, M. A. M. van Kooten, R. Jensen-Clem
For future extremely large telescopes, error in extreme adaptive optics systems at small angular separations will be highly impacted by the lag time of the correction, which is typ…
Using the Gerchberg-Saxton algorithm to reconstruct non-modulated pyramid wavefront sensor measurements
Vincent Chambouleyron, Aditya Sengupta, Maïssa Salama +9
Adaptive optics (AO) is a technique to improve the resolution of ground-based telescopes by correcting, in real-time, optical aberrations due to atmospheric turbulence and the tele…
A Wolf 359 in sheep's clothing: Hunting for substellar companions in the fifth-closest system using combined high-contrast imaging and radial velocity analysis
Rachel Bowens-Rubin, Joseph M. Akana Murphy, Philip M. Hinz +16
Wolf 359 (CN Leo, GJ 406, Gaia DR3 3864972938605115520) is a low-mass star in the fifth-closest neighboring system (2.41 pc). Because of its relative youth and proximity, Wolf 359…
Deformable mirror-based pupil chopping for exoplanet imaging and adaptive optics
Javier Perez Soto, Cesar Laguna, Benjamin L. Gerard +3
Due to turbulence in the atmosphere images taken from ground-based telescopes become distorted. With adaptive optics (AO) images can be given greater clarity allowing for better ob…
First laboratory demonstration of real-time multi-wavefront sensor single conjugate adaptive optics
Benjamin L. Gerard, Daren Dillon, Sylvain Cetre +1
Exoplanet imaging has thus far enabled studies of wide-orbit (10 AU) giant planet (2 Jupiter masses) formation and giant planet atmospheres, with future 30 meter-class Extrem…
High Speed Focal Plane Wavefront Sensing with an Optical Chopper
Benjamin L. Gerard, Daren Dillon, Sylvain Cetre +1
Focal plane wavefront sensing and control is a critical approach to reducing non-common path errors between the a conventional astronomical adaptive optics (AO) wavefront sensor (W…
Astrometric Accelerations as Dynamical Beacons: A Giant Planet Imaged Inside the Debris Disk of the Young Star AF Lep
Kyle Franson, Brendan P. Bowler, Yifan Zhou +13
We present the direct imaging discovery of a giant planet orbiting the young star AF Lep, a 1.2 member of the 24 3 Myr Pic moving group. AF Lep was observed a…
Surveying Nearby Brown Dwarfs with HGCA: Direct Imaging Discovery of a Faint, High-Mass Brown Dwarf Orbiting HD 176535 A
Yiting Li, Timothy D. Brandt, G. Mirek Brandt +16
Brown dwarfs with well-measured masses, ages and luminosities provide direct benchmark tests of substellar formation and evolutionary models. We report the first results from a dir…
