Researchers from Technical University Report Findings in Astrophysics Research (The PLATO Simulator: modelling of high-precision high-cadence space-based imaging)

By a News Reporter-Staff News Editor at Physics Week -- New research on Astrophysics Research is the subject of a report. According to news reporting originating in Berlin, Germany, by VerticalNews journalists, research stated, "Many aspects of the design trade-off of a space-based instrument and its performance can best be tackled through simulations of the expected observations. The complex interplay of various noise sources in the course of the observations make such simulations an indispensable part of the assessment and design study of any space-based mission."

The news reporters obtained a quote from the research from Technical University, "We present a formalism to model and simulate photometric time series of CCD images by including models of the CCD and its electronics, the telescope optics, the stellar field, the jitter movements of the spacecraft, and all of the important natural noise sources. This formalism has been implemented in a versatile end-to-end simulation software tool, specifically designed for the PLATO (Planetary Transists and Oscillations of Stars) space mission to be operated from L2, but easily adaptable to similar types of missions. We call this tool Plato Simulator. We provide a detailed description of several noise sources and discuss their properties in connection with the optical design, the allowable level of jitter, the quantum efficiency of the detectors, etc. The expected overall noise budget of generated light curves is computed, as a function of the stellar magnitude, for different sets of input parameters describing the instrument properties."

According to the news reporters, the research concluded: "The simulator is offered to the scientific community for future use."
