Observational Constraints in Metric-Affine Gravity
arXiv:2103.12036 · doi:10.1140/epjc/s10052-021-09275-6
Abstract
We derive the main classical gravitational tests for a recently found vacuum solution with spin and dilation charges in the framework of Metric-Affine gauge theory of gravity. Using the results of the perihelion precession of the star S2 by the GRAVITY collaboration and the gravitational redshift of Sirius B white dwarf we constrain the corrections provided by the torsion and nonmetricity fields for these effects.
