Efficient spectroscopy of exoplanets at small angular separations with vortex fiber nulling
Garreth Ruane, Ji Wang, Dimitri Mawet +4
Instrumentation designed to characterize potentially habitable planets may combine adaptive optics and high-resolution spectroscopy techniques to achieve the highest possible sensi…
Direct Imaging in Reflected Light: Characterization of Older, Temperate Exoplanets With 30-m Telescopes
Etienne Artigau, Rebecca A. Bernstein, Timothy Brandt +22
Direct detection, also known as direct imaging, is a method for discovering and characterizing the atmospheres of planets at intermediate and wide separations. It is the only means…
The Planetary Systems Imager: 2-5 Micron Channel
Andrew J. Skemer, Deno Stelter, Dimitri Mawet +15
We summarize the red channel (2-5 micron) of the Planetary Systems Imager (PSI), a proposed second-generation instrument for the TMT. Cold exoplanets emit the majority of their lig…
Characterization of microdot apodizers for imaging exoplanets with next-generation space telescopes
Manxuan Zhang, Garreth Ruane, Jacques-Robert Delorme +5
A major science goal of future, large-aperture, optical space telescopes is to directly image and spectroscopically analyze reflected light from potentially habitable exoplanets. T…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes III. Technology opportunities and pathways
Frans Snik, Olivier Absil, Pierre Baudoz +30
The Optimal Optical CoronagraphWorkshop at the Lorentz Center in September 2017 in Leiden, the Netherlands gathered a diverse group of 25 researchers working on exoplanet instrumen…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes II. Common path wavefront sensing/control and Coherent Differential Imaging
Nemanja Jovanovic, Olivier Absil, Pierre Baudoz +28
The Optimal Optical Coronagraph (OOC) Workshop held at the Lorentz Center in September 2017 in Leiden, the Netherlands, gathered a diverse group of 25 researchers working on exopla…
Review of high-contrast imaging systems for current and future ground- and space-based telescopes I. Coronagraph design methods and optical performance metrics
G. Ruane, A. Riggs, J. Mazoyer +29
The Optimal Optical Coronagraph (OOC) Workshop at the Lorentz Center in September 2017 in Leiden, the Netherlands gathered a diverse group of 25 researchers working on exoplanet in…
High-contrast spectroscopy testbed for Segmented Telescopes: instrument overview and development progress
N. Jovanovic, G. Ruane, D. Echeverri +11
The High Contrast spectroscopy testbed for Segmented Telescopes (HCST) is being developed at Caltech. It aims at addressing the technology gap for future exoplanet imagers and prov…
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…
