The growing field of post-main-sequence exoplanetary science

Dimitri Veras

University of Warwick, UK


Connecting planetary systems at different stages of stellar evolution helps us understand their formation, evolution and fate, as well as provides us with crucial insights about their dynamics and chemistry. Post-main-sequence stars -- giant branch stars, white dwarfs and pulsars -- all host planetary systems. Here I provide a review of our current knowledge of these systems, including an update on the observational and theoretical aspects of the groundbreaking discovery of at least one disintegrating minor planet transiting white dwarf WD 1145+017. I show how this field incorporates several facets of solar system physics and chemistry, and how its interdisciplinary nature requires input from orbital dynamics, stellar evolution, asteroseismology, astrochemistry, atmospheric science and surface processes.
