Obliquity Constraints for the Extremely Eccentric Sub-Saturn Kepler-1656 b

Ryan A. Rubenzahl, Andrew W. Howard, Samuel Halverson +25

The orbits of close-in exoplanets provide clues to their formation and evolutionary history. Many close-in exoplanets likely formed far out in their protoplanetary disks and migrat…

Orbital alignment of the eccentric warm Jupiter TOI-677 b

Elyar Sedaghati, Andrés Jordán, Rafael Brahm +3

Warm Jupiters lay out an excellent laboratory for testing models of planet formation and migration. Their separation from the host star makes tidal reprocessing of their orbits ine…

A gap-sharing planet pair shaping the crescent in HD 163296: a disk sculpted by a resonant chain

Juan Garrido-Deutelmoser, Cristobal Petrovich, Carolina Charalambous +2

ALMA observations of the disk around HD 163296 have resolved a crescent-shape substructure at around 55 au, inside and off-center from a gap in the dust that extends from 38 au to…

A Machine Learns to Predict the Stability of Tightly Packed Planetary Systems

Daniel Tamayo, Ari Silburt, Diana Valencia +9

The requirement that planetary systems be dynamically stable is often used to vet new discoveries or set limits on unconstrained masses or orbital elements. This is typically carri…

Planetary engulfment as a trigger for white dwarf pollution

Cristobal Petrovich, Diego J. Muñoz

The presence of a planetary system can shield a planetesimal disk from the secular gravitational perturbations due to distant outer massive objects (planets or stellar companions).…

Rotochemical heating of millisecond and classical pulsars with anisotropic and density-dependent superfluid gap models

Nicolás González-Jiménez, Cristobal Petrovich, Andreas Reisenegger

When a rotating neutron star loses angular momentum, the progressive reduction of the centrifugal force makes it contract. This perturbs each fluid element, raising the local press…
