| Abstract : | The Magellanic Bridge is a vital signature of interaction between the Magellanic Clouds, which hosts several UV-bright star clusters and associations. However, the properties of many of these clusters/associations have not been extensively studied. In this work, we aimed to parametrize these objects in multiple regions within the Magellanic Bridge using FUV and NUV data from the UVIT/Astrosat, and by combining them with Gaia DR3. We reduced the available UVIT data for one such region in the Bridge, located near the Small Magellanic Cloud, using CCDLAB. We performed PSF photometry and estimated FUV v/s FUV-NUV and NUV v/s FUV-NUV colour magnitude diagrams (CMDs) for three already identified objects in this region: BS191, BS195, and OGLB51. The UVIT data was crossmatched with Gaia DR3 data to obtain proper motion and parallax for the stars. Using statistical methods, appropriate PM and parallax cuts were applied to eliminate Galactic contaminations. The ages and extinctions were estimated from the best-fitted padova models to the main-sequence, assuming a constant distance (61 kpc) and metallicity (Z=0.004). We find that all the three objects are aged between a few Myr and a few 10 Myr. Comparing our results with the recent catalogue of Bica et al. 2020 indicates that this is probably for the first time that ages of these objects have been estimated. Based on the CMDs, we speculate that BS191 and BS195 are probable cluster candidates, while OGLB51 is an association, contrary to what has been catalogued in Bica et al. |
