How do planets form? What fraction of planets that form could potentially sustain some form of life? What role does the star, the protoplanetary disk, and the star cluster play in the outcome? How is the composition of a planet affected by that of the star? Which planets manifest plate tectonics and which do not? What is the role of water in the evolution of a planet? These are some of the nearly endless questions that we ask ourselves during the 'Astrophysical Origins: Pathways from Star Formation to Habitable Planets' event here at the Erwin Schr ödinger Institute located at the University of Vienna.

This event aims to bring together a large group of experts from a great variety of disciplines. Some of the most interdisciplinary topics of this event include: the removal of protoatmospheres of planets that were previously accreted from the protoplanetary disk; chemical and physical processing and erosion of outgassed secondary atmospheres by the action of winds and radiation from the evolving host star; and interactions between planetary atmospheres and surfaces/interiors that lead to plate tectonics and the buildup of liquid water oceans. We also aim to integrate constraints and knowledge from experts in cosmochemistry, geology, geochronology, disk observations and planet formation models.

At present there is ambiguity about the evolution of planets that are affected by the magnetic activity, high-energy radiation, high-energy particles and hot plasma winds of a star takes, depending on the (nearly arbitrary) initial rotation period of the star. Similarly, a multitude of atmospheric evolution tracks may be possible, and initial hydrogen gas envelopes of growing planetary cores depend on the independent co-evolution and dispersal of the protoplanetary disk. Here we aim to identifying favourable niches for planets to reside in that can eventually develop life, on what timescale, and what are the precursor conditions that lead up to this state.

We bring together a large and diverse group of experts covering major theme fields with varying degrees of overlap. We aim to have a 'big picture' discussion at the end of each week. The schedule is left free to be determined by the participants of each week and by the conclusions and progress that has been made the week(s) before.
