Query: 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.
