  We compare the radial profiles of the specific star formation rate (sSFR) in
a sample of 169 star-forming galaxies in close pairs with those of mass-matched
control galaxies in the SDSS-IV MaNGA survey. We find that the sSFR is
centrally enhanced (within one effective radius) in interacting galaxies by
~0.3 dex and that there is a weak sSFR suppression in the outskirts of the
galaxies of ~0.1 dex. We stack the differences profiles for galaxies in five
stellar mass bins between log(M/Mstar) = 9.0-11.5 and find that the sSFR
enhancement has no dependence on the stellar mass. The same result is obtained
when the comparison galaxies are matched to each paired galaxy in both stellar
mass and redshift. In addition, we find that that the sSFR enhancement is
elevated in pairs with nearly equal masses and closer projected separations, in
agreement with previous work based on single-fiber spectroscopy. We also find
that the sSFR offsets in the outskirts of the paired galaxies are dependent on
whether the galaxy is the more massive or less massive companion in the pair.
The more massive companion experiences zero to a positive sSFR enhancement
while the less massive companion experiences sSFR suppression in their
outskirts. Our results illustrate the complex tidal effects on star formation
in closely paired galaxies.
