Environmental and secular processes play a pivotal role in the evolution ofgalaxies. These can be due to external processes such as interactions orinternal processes due to the action of bar, bulge and spiral structures.Ongoing star formation in spiral galaxies can be affected by these processes.Studying the star formation in the galaxy can give insights into the evolutionof the galaxy. The ongoing interaction between barred-spiral galaxy NGC 1512and its satellite NGC 1510 offers an opportunity to investigate how galacticinteractions and the presence of a galactic bar influence the evolution of NGC1512. We aim to understand the recent star formation activity in the galaxypair and thus gain insight into the evolution of NGC 1512. The UltraVioletImaging Telescope (UVIT) onboard AstroSat enables us to study the star-formingregions in the galaxy with a spatial resolution of ~85 pc in the galaxy restframe. We identified and studied 175 star-forming regions in UVIT FUV image ofNGC 1512 and correlated with the neutral hydrogen (HI) distribution. Wedetected localized regions of star formation enhancement and distortions in thegalactic disk. This is consistent with HI distribution in the galaxy. This isevidence of past and ongoing interactions affecting the star formationproperties of the galaxy. We studied the properties of the inner ring. We findthat the regions of the inner ring show maximum star formation rate density(log(SFRDmean[Msolaryr-1kpc-2]) ~ -1.7) near the major axis of the bar, hintingat a possible crowding effect in these regions. The region of the bar in thegalaxy is also depleted of UV emission. This absence suggests that the galacticbar played an active role in the redistribution of gas and quenching of starformation inside identified bar region. Hence, we suggest that both the secularand environmental factors might influence the evolution of NGC 1512.
