| Abstract: We study the chemical abundances of active Sun-like stars (SLSs) by analysing their photospheric composition using high-resolution optical spectra obtained from the HARPS and UVES instruments mounted on the ESO 3.6-m and VLT, respectively. Accurate abundance determination requires precise estimation of stellar parameters such as effective temperature (Teff ), surface gravity (log g), metallicity ([Fe/H]), and microturbulent velocity (vmic). These parameters are derived using both equivalent width and spectral synthesis methods. After applying radial velocity corrections, we obtained refined abundance values for the star. These photospheric abundances will be further used to compare the coronal abundances of the same star.
