The First Greek-Austrian Workshop on Extrasolar Planetary Systems was held on the island of Ammouliani, Chalkidiki, Greece, September 18-25, 2016.

This volume contains the participants' contributions that illuminate many aspects of exoplanets. Each paper went through an independent review and represents the state-of-the-art in its respective field.

Graduate students as well as active research scientists in this exciting and dynamically evolving field will benefit from this book.
