Zodiacal Exoplanets in Time (ZEIT): The AO follow-up Program
Abstract
Planets and their host stars evolve with time, and the first Gyr is thought to be the most critical. By comparing planet characteristics from a range of ages we can constrain the timescales and importance of mechanisms that dictate the final planetary configuration (e.g., planet migration). The repurposed Kepler (K2) spacecraft has observed star-forming regions and young stellar clusters aged 1-850 million years, from which we have found a suite of planets. The current sample has a deficit of close-in planets at ages <= 120 Myr, suggesting a long migration timescale. Here we propose AO follow-up to confirm their planetary nature.
