My new paper, published in ApJ this month, tackles a question I always assumed the answer was “no” to in exoplanet dynamics: if a giant planet becomes a close-in hot/warm Jupiter via high-eccentricity tidal migration, …

New paper: Investigating the Formation of Planets Interior to in situ Hot Jupiters
In a his new first-author paper (now on arXiv), UW–Madison undergraduate alumni Devansh Mathur investigates what happens to small planetary embryos interior to a forming hot Jupiter. Using hundreds of N-body simulations, he showed that …
New paper: How Einstein’s Theory Might Help Planets Around White Dwarfs Stay Habitable
A new paper led by UW-Madison undergraduate Eva Stafne and published in ApJ this week (arXiv preprint here) explores how general relativity (the same physics that explains Mercury’s orbit) could help preserve life-friendly conditions on …
New paper: Tides Tighten the Hycean Habitable Zone
Hycean planets (ocean worlds with H-rich atmospheres) are thought to be promising spots for life, particularly around M-dwarfs, with the habitable zone being much wider than it is for terrestrial planets. But there’s a twist… …
