Accretion discs around binary star systems are ubiquitous in the galaxy and planet formation is thought to occur within these discs. Circumbinary discs are commonly observed to be misaligned with respect to the binary orbital plane. A misaligned circumbinary disc eventually evolves to a stable orientation, either coplanar or polar to the binary orbital plane. The process of disc alignment has important implications for planet formation. By understanding the structure and evolution of these discs and also debris discs, I shed light on the observed characteristics of exoplanets. My focus is to study the gas dynamics around binary and higher-order star systems with an emphasis on explaining observations and developing theoretical models to better constrain planet formation mechanisms. My results unravel robust planet formation scenarios, which have far reaching implications for the present and upcoming observations from space telescope TESS. Furthermore, the next-generation telescopes, such as James Webb Space Telescope and Thirty Meter Telescope will fuel the discovery of planets within binary and higher-order star systems.
