Central Star Formation in Early-type Galaxy I Zw 81 in the Bootes Void

The origin of star-formation in customarily passively evolving early-type massive galaxies is poorly understood. We present a case study galaxy, I~Zw~81, inside the Bootes void. void galaxy known to host an active galactic nuclei (AGN). Our detailed 2D decomposition surface brightness distribution $Canada$ $France$ $Hawaii$ $Telescope$ ($CFHT$) g- and r-bands revealed multiple structural components such as nuclear point source, bar, ring, inner exponential disk followed by outer low (LSB) disk. I~Zw~81 turns out be disk-dominated with lenticular morphology. modelling multi-wavelength spectral energy (SED) shows that star-forming (SF), belongs blue cloud. find optical (g$-$r) color bar bluer than disks, far- near-ultraviolet emission observed Ultraviolet Imaging Telescope (UVIT) onboard {\em AstroSat} concentrated central few kpc region enclosing bar. strong might playing pivotal role driving gas inflow causing SF activity tandem minor merger-like interactions evident from deep $CFHT$ data. low-luminosity AGN insufficient quench SF. results are peculiar standpoint barred galaxy.
