Numerous discoveries of exoplanets over the past few years have proven that planet formation is the rule rather than an exception. At the same time, astrophysicists have made huge progress in observations of the birthplaces of planets and learned more about the risks that prevail specifically in the environment around young stars. Despite these important discoveries, the planet formation process as a whole remains a puzzling as its intermediate stages are essentially unobservable.
Models for the early stages of planet formation
This is where Joanna Drążkowska comes in with Planetoids (Formation of planetary building blocks throughout time and space). Her ERC project aims at constructing innovative numerical models of the early stages of planet formation when the dust grows to pebbles and eventually becomes gravitationally bound in building blocks of planets called planetesimals. Global models are scarce for this important phase of planet formation.
Joanna Drążkowska studied astronomy at the Nicolaus Copernicus University in Toruń, Poland, and received her doctoral degree in 2014 from the Institute of Theoretical Astrophysics at the University of Heidelberg. After three years as a postdoctoral researcher at the “PlanetS” National Centre of Competence in Research at the University of Zurich, she moved in 2018 to LMU’s University Observatory to work under the guidance of Professor Til Birnstiel. In 2021, Joanna Drążkowska received the A&A (Astrophysics & Astronomy) Early Career Award.
