Observational constraints in metric-affine gravity

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.

Automated summary

In this study, the main classical gravitational tests were derived for a vacuum solution with spin and dilation charges in the Metric-Affine gauge theory of gravity. The corrections provided by the torsion and nonmetricity fields for the effects of perihelion precession of the star S2 and gravitational redshift of Sirius B white dwarf were constrained using observational data.
