Various migration theories with different timescales, e.g., primordial disk misalignment (&lt; 3 Myr), Kozai-Lidov mechanism (10 kyr - 100 Myr), secular chaos (10 Myr - 100 Myr), differ strongly in their predictions on the obliquity. These mechanisms all functions during the youth of the planetary systems (&lt; 1 Gyr). Young planetary systems are the promising targets to constrain the models and timescales of planetary formation and migration.</p> <font size=3> <h2 id="related-works">Related works:</h2> <a href="https://hyteng.netlify.app/publication/teng2024/" target="_blank"> “The ∼50Myr Old TOI-942c is Likely on an Aligned, Coplanar Orbit and Losing Mass”</a> </font>
