Imaging the 44 AU Kuiper Belt-analogue debris ring around HD 141569A with GPI polarimetry
J. S. Bruzzone, S. Metchev, G. Duchene +53
We present the first polarimetric detection of the inner disk component around the pre-main sequence B9.5 star HD 141569A. Gemini Planet Imager H-band (1.65 micron) polarimetric di…
An updated visual orbit of the directly-imaged exoplanet 51 Eridani b and prospects for a dynamical mass measurement with Gaia
Robert J. De Rosa, Eric L. Nielsen, Jason J. Wang +52
We present a revision to the visual orbit of the young, directly-imaged exoplanet 51 Eridani b using four years of observations with the Gemini Planet Imager. The relative astromet…
orbitize!: A Comprehensive Orbit-fitting Software Package for the High-contrast Imaging Community
Sarah Blunt, Jason Wang, Isabel Angelo +10
orbitize! is an open-source, object-oriented software package for fitting the orbits of directly-imaged objects. It packages the Orbits for the Impatient (OFTI) algorithm and a par…
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…
Demonstrating predictive wavefront control with the Keck II near-infrared pyramid wavefront sensor
Rebecca Jensen-Clem, Charlotte Z. Bond, Sylvain Cetre +5
The success of ground-based instruments for high contrast exoplanet imaging depends on the degree to which adaptive optics (AO) systems can mitigate atmospheric turbulence. While m…
