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…
Dynamical Constraints on the HR 8799 Planets with GPI
Jason J. Wang, James R. Graham, Rebekah Dawson +52
The HR 8799 system uniquely harbors four young super-Jupiters whose orbits can provide insights into the system's dynamical history and constrain the masses of the planets themselv…
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…
