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…
The Keck Planet Imager and Characterizer: A dedicated single-mode fiber injection unit for high resolution exoplanet spectroscopy
Jacques-Robert Delorme, Nemanja Jovanovic, Daniel Echeverri +28
The Keck Planet Imager and Characterizer (KPIC) is a purpose-built instrument to demonstrate new technological and instrumental concepts initially developed for the exoplanet direc…
