ABSTRACT We present a simple regulator-type framework designed specifically for modelling formation of dwarf galaxies. Despite its simplicity, when coupled with realistic mass accretion histories haloes from simulations and reasonable choices model parameter values, the can reproduce remarkably broad range observed properties galaxies over seven orders magnitude in stellar mass. In particular, ...

ABSTRACT Variability observed in photometric light curves of late-type stars (on time-scales longer than a day) is dominant noise source exoplanet surveys and results predominantly from surface manifestations stellar magnetic activity, namely faculae spots. The implementation light-curve models an open problem, with scaling typically based on spectra equivalent to hot atmospheres or assuming so...
