The central early-type galaxy hosts evolved stellar population while the ring, abuzz with active star formation is bright in UV. The high resolution FUV/NUV imaging is ideal to study the clumpy ongoing star formation in the ring and the spatial variation of star formation rate. As part of an ongoing deep imaging survey of R-ETGs using the UVIT, we are conducting the deepest and highest spatial resolution UV observations of a selected list of these galaxies using UVIT onbaord ASTROSAT. The analysis and the initial results of the study will be presented. |
