DSTREAM - Disk Systems That are Replenished and Evolve through Accretion of Material

What is your project about?

The traditional understanding of how stars and planets form is based on the idea that a star and its protoplanetary disk form from the collapse of an isolated, rotating cloud of gas and dust. Millions of years later, dust and ice particles collide and gradually form planets. Today, we know from new simulations and observations that planet formation often begins earlier, while the disk is still being fed with material through so-called “streamers” – large flows of gas and dust falling in from the surrounding environment. With DSTREAM, we will investigate how widespread these streamers are and how they affect disk evolution and planet formation. Using advanced magnetohydrodynamic simulations, we will model how material falls onto the disk and alters its properties. The project contributes new knowledge about how planetary systems form as part of a larger whole – not as isolated systems, but as open and dynamic ones in constant development.

How did you become interested in your particular field of research?

My interest in my research field arose from a deep fascination with how our own solar system once came into being. Already as a Master's student, I had the opportunity to look more closely at the link between stars and planets, as planets form in disks that arise as a byproduct of star formation. In DSTREAM, I am especially motivated by the desire to understand how the surrounding environment influences and replenishes the disks in which planets form. The combination of theoretical modeling and observations makes it possible to uncover these dynamic and crucial processes.

What are the scientific challenges and perspectives in your project?

A central research challenge in the project is to understand how the inflow of material affects the evolution of planet-forming disks. This requires high-resolution simulations where scales and physical processes range from large molecular clouds to the fine structure of the disks. The perspective is that, with DSTREAM, we can change the common perception of disks as isolated systems and instead establish a new framework where disks are seen as dynamic, open systems. This can have a significant impact on our understanding of when and how planets form and thereby on our broader knowledge of planet formation and the diversity of planetary systems.

What is your estimate of the impact, which your project may have to society in the long term?

My research contributes to a deeper understanding of our cosmic origins – how stars, planets, and thus potential hosts for life come into being. It has strong outreach potential and broad societal interest because it addresses fundamental questions about where we come from. In addition, the work advances technological and methodological development in data analysis and modeling, which can have secondary applications in other scientific and technological fields. Finally, the research inspires the next generation of scientists and strengthens scientific literacy in society.

Which impact do you expect the Sapere Aude programme will have on your career as a researcher?

Participating in the Sapere Aude program will be a decisive step in my research career. It will allow me to consolidate my independence as a researcher and build a strong research group focused on the dynamic processes that shape planetary systems. The support will provide the necessary peace of mind and capacity to pursue ambitious ideas and strengthen my international profile through collaborations and visibility. At the same time, it will pave the way for applying for larger grants and leading interdisciplinary projects, which is essential for establishing my research group at the forefront of modeling the interaction between star and planet formation.

Background and personal life

Perhaps one could say that the combination of curiosity and perseverance has always been my driving force – both in my research and in my general approach to life. I come from neither an academic family nor from Denmark, so at times it feels almost surreal to be at the Niels Bohr Institute working on fundamental questions about how our solar system came into being. It is important to me that research is not just for the few, and I hope to contribute to making science more open and inclusive. Outside of work, I find joy in everyday life, in spending time with my family (I became a father for the first time this year), and in staying active and curious – also beyond the university and the computer.
