Constraints on a fifth force from the stellar orbits around the central supermassive black hole of the Milky Way
MCMC fits of Yukawa gravity to S2 star data constrain fifth-force strength δ to ~0.005, 0.02 and 0.15 for λ ranges of hundreds to thousands of AU, all consistent with f_SP = 1.10 ± 0.19.
