Substructures in protoplanetary disks imprinted by compact planetary systems

Juan Garrido-Deutelmoser, Cristobal Petrovich, Leonardo Krapp +2

The substructures observed in protoplanetary disks may be the signposts of embedded planets carving gaps or creating vortices. The inferred masses of these planets often fall in th…

Eccentric Mergers of Intermediate-Mass Black Holes from Evection Resonances in AGN Disks

Diego J. Muñoz, Nicholas C. Stone, Cristobal Petrovich +1

We apply the theory of nonlinear resonance capture to the problem of a black hole binary (BHB) orbiting a supermassive black hole (SMBH) while embedded in the accretion disk of an…

Mutual Inclination of Ultra-Short-Period Planets with Time Varying Stellar J2-moment

Chen Chen, Gongjie Li, Cristobal Petrovich

Systems with ultra-short-period planets (USPs) tend to possess larger mutual inclinations compared to those with planets located farther from their host stars. This could be explai…

The chaotic history of the retrograde multi-planet system in K2-290A driven by distant stars

Marcela Best, Cristobal Petrovich

The equator of star K2-290A was recently found to be inclined by 124+/-6 degrees relative to the orbits of both its known transiting planets. The presence of a companion star B at…
