Um simulador Python de Sistemas Exoplanetários para curvas de luz e velocidades radiais.

pyExopS (Python Exoplanetary Systems Simulator)

pyExopS is a Python-based simulator designed to generate realistic observational data for exoplanetary systems. It aims to provide a flexible and extensible platform for studying phenomena like planetary transits, stellar activity, and various observational systematics.

Features

• Realistic Star Model: Includes quadratic limb darkening and dynamic stellar spots (umbra and penumbra).
• Planet Model: Customizable orbiting planets with definable physical and orbital parameters.
• Advanced PSF Modeling: Supports Gaussian, Moffat, Airy Disk, Elliptical Gaussian, and Combined Point Spread Functions to simulate realistic instrumental and atmospheric blurring.
• Noise Injection: Injects Poisson (photon) noise and Gaussian (readout) noise for true-to-life data.
• Photometry Methods: Implements various photometric extraction techniques:
  • Simple Aperture Photometry (SAP)
  • Optimal Photometry
  • PSF Fitting Photometry
  • Simplified Difference Imaging Photometry (DIP)
• Data Conditioning: Includes a PDCSAP-like detrending algorithm to remove instrumental and astrophysical systematics from light curves while preserving transit signals.
• Variable Cadence: Allows simulation of observations with non-uniform time sampling (e.g., high cadence during transit, low cadence out-of-transit).
• Parallel Processing: Leverages Dask for efficient parallel computation across multicore CPUs, NVIDIA GPUs (Dask-CUDA), or distributed clusters.

Installation

You can install pyExopS using pip:
