    Going back to basics: accelerating exoplanet transit modelling using Taylor-series expansion of the orbital motion
    A significant fraction of an exoplanet transit model evaluation time is spent calculating projected distances between the planet and its host star. This is a...

    Granulation in Red Giants: Observations by the Kepler Mission and Three-dimensional Convection Simulations
    The granulation pattern that we observe on the surface of the Sun is due to hot plasma rising to the photosphere where it cools down and descends back into the...
