PLATO Stellar Light-curve Simulator (SLS): Simulate stochastically-excited oscillations and associated stellar and instrumental background noises

Project description

PSLS: the PLATO Solar-like Light-curve Simulator

Simulate solar-like oscillators representative for PLATO observations. The simulator includes planetary transits, stochastically-excited oscillations, granulation and activity background components, as well as instrumental systematic errors and random noises representative for PLATO. The program also manages the existence of a time shift between groups of cameras. Planetary transits are included following Mandel & Agol (2002) equations (see…580L.171M) and using the Python implementation by Ian Crossfield ( at UCLA.

For more details see

The data package provides the code and two files storing the parameters describing the PLATO systematic errors: - PLATO_systematics_BOL.npy: End Of Life (EOL) systematic errors - PLATO_systematics_EOL.npy: Begining Of Life (BOL) systematic errors

The package also provides two working examples: - a main sequence star (0012069449.yaml) with its associated theoretical frequencies (0012069449.gsm) generated by ADIPLS pulsation code - a red giant star (0009882316.yaml), which does not require as input theoretical frequencies.

The grid of models have to be downloaded from the website.

Changes history: - 0.7 (10/12/18): inclusion of PLATO systematic errors and random noise as a function of the star V magnitude - 0.6: minor problems fixed (missing file, link problem) - 0.5: can perform simulation for a given input set of theoretical frequencies (i.e. from a given .gsm file) ; new parameters included in the configuration file .yaml ; various minor improvements - 0.4: minor changes - 0.3: first working version
