Design, pointing control, and on-sky performance of the mid-infrared vortex coronagraph for the VLT/NEAR experiment
A. -L. Maire, E. Huby, O. Absil +16
Vortex coronagraphs have been shown to be a promising avenue for high-contrast imaging in the close-in environment of stars at thermal infrared (IR) wavelengths. They are included…
Experimental analysis of the achromatic performance of a vector vortex coronagraph
Garreth Ruane, Eugene Serabyn, Camilo Mejia Prada +4
The vector vortex coronagraph is an instrument designed for direct detection and spectroscopy of exoplanets over a broad spectral range. Our team is working towards demonstrating c…
Enhanced high-dispersion coronagraphy with KPIC phase II: design, assembly and status of sub-modules
N. Jovanovic, B. Calvin, M. Porter +17
The Keck Planet Imager and Characterizer (KPIC) is a purpose-built instrument for high-dispersion coronagraphy in the K and L bands on Keck. This instrument will provide the first…
The McDonald Accelerating Stars Survey (MASS): White Dwarf Companions Accelerating the Sun-like Stars 12 Psc and HD 159062
Brendan P. Bowler, William D. Cochran, Michael Endl +7
We present the discovery of a white dwarf companion to the G1 V star 12 Psc found as part of a Keck adaptive optics imaging survey of long-term accelerating stars from the McDonald…
Detecting and characterizing close-in exoplanets with Vortex Fiber Nulling
Daniel Echeverri, Garreth Ruane, Benjamin Calvin +8
Vortex Fiber Nulling (VFN) is an interferometric method for suppressing starlight to detect and spectroscopically characterize exoplanets. It relies on a vortex phase mask and sing…
Microelectromechanical deformable mirror development for high-contrast imaging, part 1: miniaturized, flight-capable control electronics
Eduardo Bendek, Garreth Ruane, Camilo Mejia Prada +3
Deformable mirrors (DMs) are a critical technology to enable coronagraphic direct imaging of exoplanets with current and planned ground - and space-based telescopes as well as futu…
