Investigating the differential limb coupling effect for diffraction-limited spectrographs with PARVI
Andrea S. J. Lin, Ashley D. Baker, Samuel Halverson +5
A promising new architecture for extreme-precision radial velocity (EPRV) spectrographs, hunting for small-amplitude stellar Doppler shifts induced by orbiting planets, is to build…
On-sky demonstration at Palomar Observatory of the near-IR, high-resolution VIPA spectrometer
Alexis Carlotti, Alexis Bidot, David Mouillet +16
A near-IR high-resolution, R=80000 spectrometer has been developed at IPAG to directly characterize the atmosphere of exoplanets using adaptive optics (AO) assisted telescopes, and…
HD 165054: an astrometric calibration field for high-contrast imagers in Baade's Window
Meiji M. Nguyen, Robert J. De Rosa, Jason J. Wang +51
We present a study of the HD 165054 astrometric calibration field that has been periodically observed with the Gemini Planet Imager. HD 165054 is a bright star within Baade's Windo…
Characterization of the C-RED 2: A High Frame Rate Near-Infrared Camera
Rose K. Gibson, Rebecca Oppenheimer, Christopher T. Matthews +1
A new wave of precision radial velocity instruments will open the door to exploring the populations of companions of low mass stars. The Palomar Radial Velocity Instrument (PARVI)…
Revised Astrometric Calibration of the Gemini Planet Imager
Robert J. De Rosa, Meiji M. Nguyen, Jeffrey Chilcote +49
We present a revision to the astrometric calibration of the Gemini Planet Imager (GPI), an instrument designed to achieve the high contrast at small angular separations necessary t…
Asymmetries in adaptive optics point spread functions
Alexander Madurowicz, Bruce Macintosh, Vanessa P. Bailey +45
An explanation for the origin of asymmetry along the preferential axis of the PSF of an AO system is developed. When phase errors from high altitude turbulence scintillate due to F…
Performance of the Gemini Planet Imager Non-Redundant Mask and spectroscopy of two close-separation binaries HR 2690 and HD 142527
Alexandra Z. Greenbaum, Anthony Cheetham, Anand Sivaramakrishnan +51
The Gemini Planet Imager (GPI) contains a 10-hole non-redundant mask (NRM), enabling interferometric resolution in complement to its coronagraphic capabilities. The NRM operates bo…
Automated data processing architecture for the Gemini Planet Imager Exoplanet Survey
Jason Wang, Marshall Perrin, Dmitry Savransky +49
The Gemini Planet Imager Exoplanet Survey (GPIES) is a multi-year direct imaging survey of 600 stars to discover and characterize young Jovian exoplanets and their environments. We…
S4: A Spatial-Spectral model for Speckle Suppression
Rob Fergus, David W. Hogg, Rebecca Oppenheimer +2
High dynamic-range imagers aim to block out or null light from a very bright primary star to make it possible to detect and measure far fainter companions; in real systems a small…
