CHARIS Science: Performance Simulations for the Subaru Telescope's Third-Generation of Exoplanet Imaging Instrumentation
Timothy D. Brandt, Michael W. McElwain, Markus Janson +21
We describe the expected scientific capabilities of CHARIS, a high-contrast integral-field spectrograph (IFS) currently under construction for the Subaru telescope. CHARIS is part…
Direct imaging of exoplanets in the habitable zone with adaptive optics
Jared R. Males, Laird M. Close, Olivier Guyon +16
One of the primary goals of exoplanet science is to find and characterize habitable planets, and direct imaging will play a key role in this effort. Though imaging a true Earth ana…
EXCEDE Technology Development III: First Vacuum Tests
Ruslan Belikov, Julien Lozi, Eugene Pluzhnik +13
This paper is the third in the series on the technology development for the EXCEDE (EXoplanetary Circumstellar Environments and Disk Explorer) mission concept, which in 2011 was se…
Experimental study of a low-order wavefront sensor for high-contrast coronagraphic imagers: results in air and in vacuum
Julien Lozi, Ruslan Belikov, Sandrine J. Thomas +4
For the technology development of the mission EXCEDE (EXoplanetary Circumstellar Environments and Disk Explorer) - a 0.7 m telescope equipped with a Phase-Induced Amplitude Apodiza…
Lyot-based Low Order Wavefront Sensor: Implementation on the Subaru Coronagraphic Extreme Adaptive Optics System and its Laboratory Performance
Garima Singh, Olivier Guyon, Pierre Baudoz +5
High throughput, low inner working angle (IWA) phase masks coronagraphs are essential to directly image and characterize (via spectroscopy) earth-like planets. However, the perform…
On-sky speckle nulling demonstration at small angular separation with SCExAO
Frantz Martinache, Olivier Guyon, Nemanja Jovanovic +7
This paper presents the first on-sky demonstration of speckle nulling, which was achieved at the Subaru Telescope in the context of the Subaru Coronagraphic Extreme Adaptive Optics…
