  In the present work, accretion onto a static spherically symmetric black hole
in the hybrid metric-Palatini gravity is considered. The Novikov-Thorne model
for a relativistic thin accretion disk is used. The energy flux, temperature
distribution, emission spectrum and energy conversion efficiency of accretion
disks around such black holes are numerically calculated. A comparison with the
results for a Schwarzschild black hole is made and conclusions about the
viability of the model are drawn. As a result, it is obtained that the
accretion disks around black holes in hybrid metric-Palatini gravity are colder
and less luminous than in general relativity.
