  In this paper, we study circular orbits, effective potential, and
thin-accretion disk of a black hole in symmergent gravity within the
Novikov-Thorne model in a way including the energy flux and temperature
distribution. We determine bounds on symmergent gravity parameters and conclude
that the accretion disk could be used as an astrophysical tool to probe
symmergent gravity.
