Planetary architectures under the influence of a stellar binary
Milenne Ávila-Bravo, Carolina Charalambous, Claudia Aguilera-Gómez
Context. The presence of a stellar companion can strongly influence the architecture and long-term stability of planetary systems. Motivated by the discovery of exoplanets exhibiti…
A Cold and Super-Puffy Planet on a Prograde Orbit
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +36
We report the discovery of TOI-4507 b, a transiting sub-Saturn with a density 0.2 g/cm on a 105-day prograde orbit around a 700 Myr old F star. The transits were detected u…
The Influence of Cold Jupiters in the Formation of Close-in planets. II. Collisional Growth of Planetesimals
Marcela Best, Antranik A. Sefilian, Carolina Charalambous +2
Exoplanet observations have shown that the occurrence and orbital architectures of close-in super-Earths and sub-Neptunes are shaped by the presence of outer gas giant planets. Thi…
Destruction of "Peas in a Pod?" A Candidate Multi-planet System Around the Nearby, Bright Star, HD208487
Rafael I. Rubenstein, James S. Jenkins, Pablo A. Peña R. +15
We re-investigate the HD208487 system to test the reality of the proposed HD208487c world. We also search for additional companions using applied Bayesian statistics and 15+ years…
The HR 8799 Debris Disc: Shaped by Planetary Migration and a Possible Fifth Outermost Planet
Pedro P. Poblete, Tim D. Pearce, Carolina Charalambous
Context. The HR 8799 system, hosting four giant planets between a warm and cold debris disc, and an extended dusty tail beyond, serves as an ideal laboratory for studying planetary…
Breaking long-period resonance chains with stellar flybys
C. Charalambous, N. Cuello, C. Petrovich
Context. Planetary migration models predict multiple planets captured into a chain of mean-motion resonances during the disk phase. Over a dozen systems have been observed in these…
