The Mass, Orbit, and Tidal Evolution of the Quaoar-Weywot System
W. C. Fraser, K. Batygin, M. E. Brown +1
Here we present new adaptive optics observations of the Quaoar-Weywot system. With these new observations we determine an improved system orbit. Due to a 0.39 day alias that exists…
The cool brown dwarf Gliese 229 B is a close binary
Jerry W. Xuan, A. Mérand, W. Thompson +76
Owing to their similarities with giant exoplanets, brown dwarf companions of stars provide insights into the fundamental processes of planet formation and evolution. From their orb…
No evidence for interstellar planetesimals trapped in the Solar System
A. Morbidelli, K. Batygin, R. Brasser +1
In two recent papers published in MNRAS, Namouni and Morais (2018, 2020) claimed evidence for the interstellar origin of some small Solar System bodies, including i) objects in ret…
Migration of Jupiter mass planets in discs with laminar accretion flows
E. Lega, A. Morbidelli, R. P. Nelson +4
Migration of giant planets in discs with low viscosity has been studied recently. The proportionality between migration speed and the disc's viscosity is broken by the presence of…
In-situ enrichment in heavy elements of hot Jupiters
A. Morbidelli, K. Batygin, E. Lega
Context: Radius and mass measurements of short-period giant planets reveal that many of these planets contain a large amount of heavy elements, in sharp contrast with the expectati…
Planet-Induced Stellar Pulsations in HAT-P-2's Eccentric System
J. de Wit, N. K. Lewis, H. A. Knutson +13
Extrasolar planets on eccentric short-period orbits provide a laboratory in which to study radiative and tidal interactions between a planet and its host star under extreme forcing…
