HD 83443c: A highly eccentric giant planet on a 22-year orbit
Adriana Errico, Robert A. Wittenmyer, Jonathan Horner +19
We report the discovery of a highly eccentric long-period Jovian planet orbiting the hot-Jupiter host HD\,83443. By combining radial velocity data from four instruments (AAT/UCLES,…
A New Type of Exoplanet Direct Imaging Search: The SCExAO/CHARIS Survey of Accelerating Stars
Thayne Currie, Timothy Brandt, Masayuki Kuzuhara +12
We present first results from a new exoplanet direct imaging survey being carried out with the Subaru Coronagraphic Extreme Adaptive Optics project (SCExAO) coupled to the CHARIS i…
The First Dynamical Mass Measurement in the HR 8799 System
G. Mirek Brandt, Timothy D. Brandt, Trent J. Dupuy +2
HR 8799 hosts four directly imaged giant planets, but none has a mass measured from first principles. We present the first dynamical mass measurement in this planetary system, find…
The McDonald Accelerating Stars Survey (MASS): Discovery of a Long-Period Substellar Companion Orbiting the Old Solar Analog HD 47127
Brendan P. Bowler, Michael Endl, William D. Cochran +12
Brown dwarfs with well-determined ages, luminosities, and masses provide rare but valuable tests of low-temperature atmospheric and evolutionary models. We present the discovery an…
orvara: An Efficient Code to Fit Orbits using Radial Velocity, Absolute, and/or Relative Astrometry
Timothy D. Brandt, Trent J. Dupuy, Yiting Li +5
We present an open-source Python package, Orbits from Radial Velocity, Absolute, and/or Relative Astrometry (orvara), to fit Keplerian orbits to any combination of radial velocity,…
SCExAO/CHARIS Direct Imaging Discovery of a 20 au Separation, Low-Mass Ratio Brown Dwarf Companion to an Accelerating Sun-like Star
Thayne Currie, Timothy D. Brandt, Masayuki Kuzuhara +27
We present the direct imaging discovery of a substellar companion to the nearby Sun-like star, HD 33632 Aa, at a projected separation of 20 au, obtained with SCExAO/CHARIS i…
