Seminar Abstract:

Over the past two decades, the study of planets orbiting around other stars has emerged from relative obscurity to the forefront of modern astronomical and planetary sciences.  After only a brief glance at the cosmos, planets appear to be extraordinarily common. The holy grail of exoplanet research remains to detect and characterize habitable worlds orbiting distant stars.  Ultimately, the question of habitability is a question of climate.  But only recently have advanced 3D climate system models become commonly used to constrain planetary habitability.  In this seminar, we will discuss results from 3D climate models with relevance to the inner edge of the habitable zone, defined by runaway and moist greenhouse states, for Earth-like planets orbiting F-, G-, K-, and M-dwarf main sequence stars.
