| Abstract: The diverse demographics of observed exoplanets—from Super-Earths to gas giants—are a direct consequence of the physical and chemical conditions in their natal environments. This talk reconstructs the formation history of Solar-type systems, tracing their connection from the earliest phases of collapse to the final architecture of planetary systems. I will begin with the Pre-Solar Core phase, showing how our recent discoveries have reshaped our understanding of the initial stages of star formation. These cores likely determine the "Chemical Heritage" of future planets; I will discuss this by focusing on the complex organics and deuterium fractionation that set the planet’s volatile budget. Transitioning to Disk Structure, we examine how these initial conditions evolve within protoplanetary disks. We discuss the physical processes that link observed substructures—such as rings and gaps—to grain growth and planet formation. Finally, we highlight the critical synergy between observations using global facilities and the discovery of exoplanets in the Indian context, particularly via the PARAS-2 spectrograph. We conclude by discussing how future Indian missions like BOSE (Bhaskaracharya Observatory for the Search of Exoplanets) will elevate our understanding of the complete journey from Exodisk to Exoplanet.
