A Hot Jupiter with a Retrograde Orbit Around a Sun-like Star and a Toy Model of Hot Jupiters in Wide Binary Star Systems

Published in Publications of the Astronomical Society of the Pacific, 2025

Reports the angle between the spin axis of the star KELT-23A and the orbital axis of its transiting hot Jupiter companion. Also presents a toy model explaining the orbital architectures of hot Jupiters in binary star systems.

Dust Transport and Processing in Centrifugally Driven Protoplanetary Disk Winds

Published in The Astrophysical Journal, 2019

Shows that the thermal processing of silicate grains, which are lifted vertially out of protoplanetary disks and transported radially outwards due to magnetocentrifugal winds, can reproduce the crystallinity fraction of grains in the outer regions of observed disks.

On the Origin of Dynamically Isolated Hot Earths

Published in The Astrophysical Journal Letters, 2017

Demonstrates that close-in, dynamically isolated, Earth-size planets may be the cores of stripped gas giants.
