Abstract

NASA’s Transiting Exoplanet Survey Satellite ( TESS ) has begun a two-year survey of most of the sky, which will include light curves for thousands of solar-like oscillators sampled at a cadence of two minutes. To prepare for this steady stream of data, we present a mock catalog of light curves, designed to realistically mimic the properties of the TESS sample. In the process, we also present the first public release of the asteroFLAG Artificial DataSet Generator, which simulates light curves of solar-like oscillators based on input mode properties. The targets are drawn from a simulation of the Milky Way’s populations and are selected in the same way as TESS ’s true Asteroseismic Target List. The light curves are produced by combining stellar models, pulsation calculations and semi-empirical models of solar-like oscillators. We describe the details of the catalog and provide several examples. We provide pristine light curves to which noise can be added ...
