Genetic Links Between Stars, Their Circumstellar Disks and Their Planets

Explore the intricate connections between stellar properties, protoplanetary disks, and planetary formation in this seminar by Diego Turrini from INAF's Turin Astrophysical Observatory. Discover how stellar mass directly influences both the mass and accretion rates of protoplanetary disks, while stellar metallicity determines the maximum dust-to-gas ratios within these disk environments. Learn about the critical role of stellar luminosity in establishing disk thermal structures and how stellar composition affects the local abundance of essential planet-building materials, including ices and organics. Examine how the growth rates of planets are constrained by local dust and gas availability, which is governed by disk mass transport processes and planetary migration patterns. Understand why planets orbiting different types of stars experience vastly different formation environments and can follow divergent evolutionary paths even when they end up with similar final characteristics. Gain insights into recent scientific advances that illuminate this complex, multifaceted relationship between stars, their circumstellar environments, and the worlds that form within them.
