Bar quenching: Evidence from star-formation-rate indicators
  The central regions of star-forming barred spiral galaxies can be devoid of
star formation because of the redistribution of gas along the length of the
bar. However, there can be gas outside the length of the bar that can host star
formation. We study a sample of barred disc galaxies in the local Universe with
an aim to discriminate between centrally quenched and globally quenched
galaxies based on their positions on star-formation-rate(SFR)--stellar mass
plots and to find a connection between the SFR of quenched galaxies and the
length of their bar. We classified barred galaxies as centrally quenched and
globally quenched based on their position on SFR--stellar mass plots, with SFRs
derived from H$\alpha$ flux and spectral energy distribution fits on combined
ultraviolet and optical flux. We selected galaxies as passive based on the
distance from the main sequence relation. From a total 2514 barred galaxies
studied here, we present 651 with suppressed star formation in their central
region but hosting star formation outside. We also find a possible correlation
between bar length and SFR for the galaxies that are fully quenched because of
the stellar bar.
