Event Information:
The advent of space-based telescopes that provide high-precision time-series photometry, such as CoRoT and Kepler/K2, have revealed a zoo of stellar variability on timescales from minutes to months. In this talk, I will focus on classes of objects whose light curves show distinctive "dips" that can tell us a surprising amount about planet formation, evolution, and death. These include disintegrating planets, young dipper systems, likely exocomets, and unlikely alien megastructures.
