## Key points

- Study focuses on circumstellar debris disks and their role in planetary formation processes
- Debris disks are similar to the asteroid belt and Kuiper belt in our solar system
- Debris disks consist of comets and leftover planetesimals
- Collisions between objects in debris disks produce circumstellar dust
- Circumstellar dust can be observed through infrared excess or resolved imaging
- Studying debris disks provides insights into planet formation theories and the history of our solar system
- Observational studies of secondary gas in debris disks provide information about composition and dynamics
- Exploration of astrobiological potential of debris disks created during impact events onto exoplanets
- Research has implications for understanding conditions necessary for life beyond Earth

## Summary

The study focuses on circumstellar debris disks and their role in planetary formation processes. These disks are similar to the asteroid belt and the Kuiper belt in our own solar system and consist of comets and leftover planetesimals. As these objects collide with each other, they produce circumstellar dust that can be observed through infrared excess or resolved imaging. By studying these debris disks, researchers can gain insights into planet formation theories and learn more about the history of our own solar system. The thesis presents observational studies of secondary gas in debris disks, providing valuable information about their composition and dynamics. Additionally, it explores the astrobiological potential of debris disks created during impact events onto exoplanets. This research has important implications for understanding the conditions necessary for life to exist beyond Earth. , , , , .
