N2 - We carried out the study of star formation (SF) properties in one of the nearby spiral galaxies NGC 1097 using AstroSat-UVIT and GALEX observations. We analyzed SF knots in the galaxy, which are identified with UVIT observations within a central 275 arcsec (∼ de Vaucouleurs radius; R25). The ‘star formation rate’ (SFR) in the nuclear ‘starburst ring’ is 1.99±0.03 M⊙yr−1, consistent with earlier studies in other wavebands. A good correlation is observed between FUV extinction and the SFR density of the UV knots, and the slope is consistent with a similar relation for global SF properties in AGN host galaxies. Such a correlation could be due to the coincidence of high SF and high dust in the regions of higher gas density, which would then be the case for both active and normal galaxies. An alternative scenario could be a large-scale AGN impact on the host galaxy via radiation pressure on dust, triggering SF.
