Over 6,000 transiting exoplanets have been discovered to date, ranging from Earth-sized worlds to gas giants larger than Jupiter. By combining photometric and spectroscopic observations across a broad spectrum of optical to infrared wavelengths during planetary transits, we can explore the atmospheres of these distant planets. The variation in transit depth with wavelength, coupled with spectroscopic data, provides key information about the composition and structure of these atmospheres. Multi-wavelength observations allow us to uncover crucial details about the physical characteristics of these planetary systems. This presentation will focus on our observational effort to study transiting exoplanets. Additionally, I will present findings from our ongoing surveys aimed at discovering new planetary systems and examining the atmospheres of several hot Jupiters.
