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…
Visible and Near Infrared Laboratory Demonstration of a Simplified Pyramid Wavefront Sensor
Julien Lozi, Nemanja Jovanovic, Olivier Guyon +4
Wavefront sensing and control are important for enabling one of the key advantages of using large apertures, namely higher angular resolutions. Pyramid wavefront sensors are becomi…
SCExAO/CHARIS Near-IR High-Contrast Imaging and Integral Field Spectroscopy of the HIP 79977 Debris Disk
Sean Goebel, Thayne Currie, Olivier Guyon +13
We present new, near-infrared (1.1--2.4 ) high-contrast imaging of the bright debris disk surrounding HIP 79977 with the Subaru Coronagraphic Extreme Adaptive Optics system (SC…
SCExAO/CHARIS Near-Infrared Direct Imaging, Spectroscopy, and Forward-Modeling of kappa And b: A Likely Young, Low-Gravity Superjovian Companion
Thayne Currie, Timothy D. Brandt, Taichi Uyama +30
We present SCExAO/CHARIS high-contrast imaging/ integral field spectroscopy of And b, a directly-imaged low-mass companion orbiting a nearby B9V star. We detect And b…
SCExAO, an instrument with a dual purpose: perform cutting-edge science and develop new technologies
Julien Lozi, Olivier Guyon, Nemanja Jovanovic +31
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is an extremely modular high-contrast instrument installed on the Subaru telescope in Hawaii. SCExAO has a dual…
LASSO: Large Adaptive optics Survey for Substellar Objects using the new SAPHIRA detector on Robo-AO
Maissa Salama, James Ou, Christoph Baranec +13
We report on initial results from the largest infrared AO direct imaging survey searching for wide orbit (>100 AU) massive exoplanets and brown dwarfs as companions around young ne…
From Lab Testing to Science: Applying SAPHIRA HgCdTe L-APD Detectors to Adaptive Optics
Sean Goebel
Due to their high frame rates, high sensitivity, low noise, and low dark current, SAPHIRA detectors provide new capabilities for astronomical observations. The SAPHIRA detector is…
Overview of the SAPHIRA Detector for AO Applications
Sean B. Goebel, Donald N. B. Hall, Olivier Guyon +2
We discuss some of the unique details of the operation and behavior of Leonardo SAPHIRA detectors, particularly in relation to their usage for adaptive optics wavefront sensing. SA…
Pioneering high contrast science instruments for planet characterization on giant segmented mirror telescopes
N. Jovanovic, O. Guyon, J. Lozi +36
A suite of science instruments is critical to any high contrast imaging facility, as it defines the science capabilities and observing modes available. SCExAO uses a modular approa…
