Variability of Kepler Solar-like Stars Harboring Small Exoplanets
We examine Kepler light-curve variability on habitable zone transit timescales for a large uniform sample of spectroscopically studied Kepler exoplanet host stars. The stars, taken from Everett et al., are solar-like in their properties and each harbors at least one exoplanet (or candidate) of radius 2.5 Re. The variability timescale examined is typical for habitable zone planets orbiting sola...
متن کاملReversible Adaptive Regularization: Perturbed Kepler Motion and Classical Atomic Trajectories
Reversible and adaptive integration methods based on Kustaanheimo-Stiefel regular-ization and modiied Sundman transformations are applied to simulate general perturbed Kepler motion and to compute classical trajectories of atomic systems (e.g. Rydberg atoms). The new family of reversible adaptive regularization (RAR) methods also conserve angular momentum and exhibit superior energy conservatio...
متن کاملComment on 'conservative discretizations of the Kepler motion'
We show that the exact integrator for the classical Kepler motion, recently found by Kozlov (J. Phys. A: Math. Theor. 40 (2007) 4529-4539), can be derived in a simple natural way (using well known exact discretization of the harmonic oscillator). We also turn attention on important earlier references, where the exact discretization of the 4-dimensional isotropic harmonic oscillator has been app...
متن کاملSearching for exoplanets in the Kepler public data
NASA’s Kepler mission to search for extrasolar planets has collected data from hundreds of thousands of star systems, and has discovered nearly 1000 confirmed exoplanets to date in addition to over 3000 unconfirmed candidates. The mission detects exoplanets using transit photometry, which detects the transit of a planet in front of a star as transient drops in stellar intensity. Raw data is col...
متن کاملRobust, open-source removal of systematics in Kepler data
We present ARC2 (Astrophysically Robust Correction 2), an open-source Pythonbased systematics-correction pipeline to correct for the Kepler prime mission long cadence light curves. The ARC2 pipeline identifies and corrects any isolated discontinuities in the light curves, then removes trends common to many light curves. These trends are modelled using the publicly available co-trending basis ve...
