Galaxy star formation properties with respect to bar ages. We investigate how the bar ageing is related to the star formation of the host galaxy. Left: Main sequence offset (ΔMS – values from Leroy et al. 2019) of the host galaxy with respect to the bar age. Positive values of ΔMS indicate the galaxy is bursting; Negative values indicate quenching. Additionally, we bootstrap our sample 1000 times, in the grey-shaded area, finding a correlation coefficient of r=−0.699±0.003, with p-value = 0.007±0.001. The strong correlation between star formation of the host galaxy and bar ageing is in agreement with the scenario in which bars aid the quenching of the galaxy. Right: Main sequence of galaxies defined in Leroy et al. (2019) (i.e. the sSFR with respect to the galaxy mass). We show their entire sample in a grey density map, while highlighting our sample colour-coded according to bar age, contextualising our results.
