*NEW*: Introduction to Planetary Astrophysics

Syllabus:

Given that we are entering an age of planetary characterization in our galaxy, likely harboring more than ~ 1011 planets today, it is important that we understand the formation and evolution of [exo]planetary systems. Furthermore, in the next decade NASA and ESA missions are set to explore and characterize a "Mini-Solar System" about Jupiter and its moons which host vast saltwater oceans, possibly harboring life. In this short-course, appropriate for advanced undergraduate students and graduate students, we will study the physics of planets in tandem with both remote and in-situ observations. The observations have provided tight constraints on the mass, radius, orbital period, and even the approximate composition of the rocky, icy, or gaseous bodies. The course is retrograde, evolving backwards through a planet's lifetime. First, the destruction of a planet and its observational consequences is assessed via the physical processes driving evaporation. The consequences of stellar irradiation over time imply that certain close-in planets have evolved due to mass loss, which we evaluate over ~ 10 Gyr. Next ,the initial composition of the planet is deduced, tracing its origins in a protoplanetary disk environment. Finally, the observed metallicity or other properties are compared to the initial metallicity in a molecular cloud giving birth to the planets.

N.B. This course is modeled after a course taught at the University of Bern in Switzerland. The course will be offered at the Raman Research Institute and Indian Institute of Astrophysics in 8 modules from July 10- July 31st, 2019. Please see the table below for details on the course modules and lectures as they come online. This is one of the first dedicated exoplanet courses in India.
