An Imaging Search for Post-Main-Sequence Planets of Sirius B
Miles Lucas, Michael Bottom, Garreth Ruane +1
We present deep imaging of Sirius B, the closest and brightest white dwarf, to constrain post-main-sequence planetary evolution in the Sirius system. We use Keck/NIRC2 in L'-band (…
Developing Adaptive Secondary Mirror Concepts for the APF and W.M. Keck Observatory Based on HVR Technology
Philip M. Hinz, Rachel Bowens-Rubin, Christoph Baranec +16
An Adaptive secondary mirror (ASM) allows for the integration of adaptive optics (AO) into the telescope itself. Adaptive secondary mirrors, based on hybrid variable reluctance (HV…
Status of predictive wavefront control on Keck II adaptive optics bench: on-sky coronagraphic results
Maaike A. M. van Kooten, Rebecca Jensen-Clem, Sylvain Cetre +4
The behavior of an adaptive optics (AO) system for ground-based high contrast imaging (HCI) dictates the achievable contrast of the instrument. In conditions where the coherence ti…
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…
"Fast" and Furious focal-plane wavefront sensing at W. M. Keck Observatory
Steven P. Bos, Michael Bottom, Sam Ragland +3
High quality, repeatable point-spread functions are important for science cases like direct exoplanet imaging, high-precision astrometry, and high-resolution spectroscopy of exopla…
Detection and Bulk Properties of the HR 8799 Planets with High Resolution Spectroscopy
Jason J. Wang, Jean-Baptiste Ruffio, Evan Morris +49
Using the Keck Planet Imager and Characterizer (KPIC), we obtained high-resolution (R35,000) -band spectra of the four planets orbiting HR 8799. We clearly detected \water…
