Journal ArticleDOI
K2SC: flexible systematics correction and detrending of K2 light curves using Gaussian process regression
TL;DR: K2SC as discussed by the authors uses Gaussian Process regression to model position-dependent systematics and time-dependent variability simultaneously, enabling the user to remove both (e.g. for transit searches) or to remove systematics while preserving variability (for variability studies).
Journal ArticleDOI
ldtk: Limb Darkening Toolkit
Hannu Parviainen,Suzanne Aigrain +1 more
TL;DR: In this article, the authors present a Python package LDTk that automates the calculation of custom stellar limb darkening (LD) profiles and model-specific LDC coefficients using the library of PHOENIX-generated specific intensity spectra.

TL;DR: In this article, the authors reported the discovery of two transiting exoplanets, CoRoT-25b and CoRoTs26b, both of which are in the Saturn mass-regime.
Journal ArticleDOI
pytransit: fast and easy exoplanet transit modelling in python
TL;DR: PyTransit as discussed by the authors is a toolkit for the analysis of exoplanet transit light curve models using Fortran with OpenMP parallelisation and GPU-accelerated computations.
Journal ArticleDOI

TL;DR: In this article, the authors studied the atmosphere of a hot exoplanet, MASCARA-2b/KELT-20b, using four transit observations with high-resolution spectroscopy facilities.
