The Keck Planet Imager and Characterizer: Phase I fiber injection unit early performance and commissioning
Evan C. Morris, Jason J. Wang, Jean-Baptiste Ruffio +5
The Keck Planet Imager and Characterizer (KPIC) is an upgrade to the Keck II adaptive optics system and instrument suite with the goal of improving direct imaging and high-resoluti…
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…
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…
Early High-contrast Imaging Results with Keck/NIRC2-PWFS: The SR 21 Disk
Taichi Uyama, Bin Ren, Dimitri Mawet +22
High-contrast imaging of exoplanets and protoplanetary disks depends on wavefront sensing and correction made by adaptive optics instruments. Classically, wavefront sensing has bee…
Keck/NIRC2 '-Band Imaging of Jovian-Mass Accreting Protoplanets around PDS 70
Jason J. Wang, Sivan Ginzburg, Bin Ren +42
We present '-band imaging of the PDS 70 planetary system with Keck/NIRC2 using the new infrared pyramid wavefront sensor. We detected both PDS 70 b and c in our images, as well…
High-contrast Demonstration of an Apodized Vortex Coronagraph
Jorge Llop-Sayson, Garreth Ruane, Dimitri Mawet +7
High contrast imaging is the primary path to the direct detection and characterization of Earth-like planets around solar-type stars; a cleverly designed internal coronagraph suppr…
