Technical description and performance of the phase II version of the Keck Planet Imager and Characterizer
Nemanja Jovanovic, Daniel Echeverri, Jacques-Robert Delorme +46
The Keck Planet Imager and Characterizer (KPIC) is a series of upgrades for the Keck II Adaptive Optics (AO) system and the NIRSPEC spectrograph to enable diffraction limited, high…
The high-contrast performance of the Keck Planet Imager and Characterizer
Jason J. Wang, Dimitri Mawet, Jerry W. Xuan +25
The Keck Planet Imager and Characterizer (KPIC), a series of upgrades to the Keck II Adaptive Optics System and Instrument Suite, aims to demonstrate high-resolution spectroscopy o…
Implicit Electric Field Conjugation Through a Single-mode Fiber
Joshua Liberman, Jorge Llop-Sayson, Arielle Bertrou-Cantou +4
Connecting a coronagraph instrument to a spectrograph via a single-mode optical fiber is a promising technique for characterizing the atmospheres of exoplanets with ground and spac…
Keck Primary Mirror Closed-Loop Segment Control using a Vector-Zernike Wavefront Sensor
Maissa Salama, Charlotte Guthery, Vincent Chambouleyron +17
We present the first on-sky segmented primary mirror closed-loop piston control using a Zernike wavefront sensor (ZWFS) installed on the Keck II telescope. Segment co-phasing error…
Vortex Fiber Nulling for Exoplanet Observations: Implementation and First Light
Daniel Echeverri, Jerry Xuan, Nemanja Jovanovic +31
Vortex fiber nulling (VFN) is a single-aperture interferometric technique for detecting and characterizing exoplanets separated from their host star by less than a diffracted beam…
On-sky speckle nulling through a single-mode fiber with the Keck Planet Imager and Characterizer
Yinzi Xin, Jerry W. Xuan, Dimitri Mawet +14
The Keck Planet Imager and Characterizer (KPIC) is an instrument at the Keck II telescope that enables high-resolution spectroscopy of directly imaged exoplanets and substellar com…
