Abstract

To investigate the impact of interaction in the North-Eastern Small Magellanic Cloud (SMC) shell region, we used far-UV images from eleven observed fields obtained from the Ultra Violet Imaging Telescope. Cleaned, science-ready images were created and point spread function photometry was performed to extract photometric data. The detected FUV stars were cross-matched with the Gaia EDR3 data to select SMC stars and to obtain kinematic information. The findings from the analysis of the FUV-optical CMDs suggest a history of episodic star formation with most of the stars with age > 150 Myr, along with stars as young as 7 Myr. The spatial distribution of FUV stars shows a gradient decreasing radially outwards. We plan to perform a detailed analysis of the morphology, density, and kinematics of the young stars in this region.
