Sergei A. Klioner, Sven Zschocke, Michael H. Soffel, Alexey G., Butkevich
TL;DR
This paper discusses how high-precision astrometric observations, like Gaia, can be used to test the violation of Local Lorentz Invariance, framing these observations as Michelson-Morley type experiments.
Contribution
It highlights the potential of future astrometric projects to serve as sensitive tests for Local Lorentz Invariance violations.
Findings
Astrometric observations can test LLI violations.
Future projects like Gaia will improve LLI testing.
Astrometry acts as a Michelson-Morley type experiment.
Abstract
This paper summarizes the analysis of the consequences of the violation of the Local Lorentz Invariance (LLI) on astrometric observations. We demonstrate that from the point of view of the LLI astrometric observations represent an experiment of Michelson-Morley type. The future high-accuracy astrometric projects (e.g., Gaia) will be used to test the LLI.
