  Brandt, T. D.: New Techniques for High-contrast Imaging with ADI: The ACORNS-ADI SEEDS Data Reduction Pipeline
  We describe Algorithms for Calibration, Optimized Registration, and Nulling the Star in Angular Differential Imaging (ACORNS-ADI), a new, parallelized software package to reduce high-contrast imaging data, and its application to data from the SEEDS survey. We implement several new algorithms, including a method to register saturated images, a trimmed mean for combining an image sequence that... Read More

  Kenworthy, M. A.: Coronagraphic Observations of Fomalhaut at Solar System Scales
  We report on a search for low mass companions within 10 AU of the star Fomalhaut, using narrowband observations at 4.05 μm obtained with the Apodizing Phase Plate coronagraph on the VLT/NaCo. Our observations place a model-dependent upper mass limit of 12-20 M _jup from 4 to 10 AU, covering the semimajor axis search space between interferometric imaging measurements and other direct...

  Carson, J.: Direct Imaging Discovery of a "Super-Jupiter" around the Late B-type Star κ And
  We present the direct imaging discovery of an extrasolar planet, or possible low-mass brown dwarf, at a projected separation of 55 ± 2 AU (1.''058 ± 0.''007) from the B9-type star κ And. The planet was detected with Subaru/HiCIAO during the SEEDS survey and confirmed as a bound companion via common proper motion measurements. Observed near-infrared magnitudes of J = 16.3 ± 0.3, H = 15.2 ±... Read More

  Thalmann, C.: Imaging Discovery of the Debris Disk around HIP 79977
  We present Subaru/HiCIAO H-band high-contrast images of the debris disk around HIP 79977, whose presence was recently inferred from an infrared excess. Our images resolve the disk for the first time, allowing characterization of its shape, size, and dust grain properties. We use angular differential imaging (ADI) to reveal the disk geometry in unpolarized light out to a radius of ~2'', as well as... Read More

  France, K.: The Ultraviolet Radiation Environment around M dwarf Exoplanet Host Stars
  The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. Ultraviolet photons influence the atmospheric temperature profiles and production of potential biomarkers on Earth-like planets around these stars. At present, little observational or theoretical basis exists for understanding the ultraviolet spectra of... Read More
