NGTS clusters survey. I. Rotation in the young benchmark open cluster Blanco 1
Edward Gillen, Joshua T. Briegal, Simon T. Hodgkin +18
We determine rotation periods for 127 stars in the ~115 Myr old Blanco 1 open cluster using ~200 days of photometric monitoring with the Next Generation Transit Survey (NGTS). Thes…
emcee v3: A Python ensemble sampling toolkit for affine-invariant MCMC
Daniel Foreman-Mackey, Will M. Farr, Manodeep Sinha +10
emcee is a Python library implementing a class of affine-invariant ensemble samplers for Markov chain Monte Carlo (MCMC). This package has been widely applied to probabilistic mode…
Four newborn planets transiting the young solar analog V1298 Tau
Trevor J. David, Erik A. Petigura, Rodrigo Luger +4
Exoplanets orbiting pre-main sequence stars are laboratories for studying planet evolution processes, including atmospheric loss, orbital migration, and radiative cooling. V1298 Ta…
Towards precise stellar ages: combining isochrone fitting with empirical gyrochronology
Ruth Angus, Timothy D. Morton, Daniel Foreman-Mackey +7
We present a new age-dating technique that combines gyrochronology with isochrone fitting to infer ages for FGKM main-sequence and subgiant field stars. Gyrochronology and isochron…
Analytic Planetary Transit Light Curves and Derivatives for Stars with Polynomial Limb Darkening
Eric Agol, Rodrigo Luger, Daniel Foreman-Mackey
We derive analytic, closed-form solutions for the light curve of a planet transiting a star with a limb darkening profile which is a polynomial function of the stellar elevation, u…
Detection of Hundreds of New Planet Candidates and Eclipsing Binaries in K2 Campaigns 0-8
Ethan Kruse, Eric Agol, Rodrigo Luger +1
We implement a search for exoplanets in campaigns zero through eight (C0-8) of the K2 extension of the Kepler spacecraft. We apply a modified version of the QATS planet search algo…
