Dissipative Capture of Planets into First-order Mean-motion Resonances
The Astrophysical Journal Letters, 2023 The emergence of orbital resonances among planets is a natural consequence of the early dynamical evolution of planetary systems. While it is well established that convergent migration is necessary for mean-motion commensurabilities to emerge, recent ...

Evidence for Hidden Nearby Companions to Hot Jupiters
The Astronomical Journal, 2023 The first discovered extrasolar worlds—giant, “hot Jupiter” planets on short-period orbits—came as a surprise to solar system–centric models of planet formation, prompting the development of new theories for planetary system evolution.

, 2021 Studies of planet migration derived from disc planet interactions began before the discovery of exoplanets. The potential importance of migration for determining orbital architectures being realised, the field received greater attention soon after the initial discoveries of exoplanets.

Unconditional hospitality: art and commons under planetary migration
Journal of Aesthetics & Culture, 2022 In both European and non-European cities, public spaces are formed by racist and segregative politics that influence everyday life. Planetary migration flows and recently implemented border politics tend to leave the most vulnerable in precarious ...

Brownian Motion in Planetary Migration [PDF]
The Astrophysical Journal, 2006 A residual planetesimal disk of mass 10-100 Earth masses remained in the outer solar system following the birth of the giant planets, as implied by the existence of the Oort cloud, coagulation requirements for Pluto, and inefficiencies in planet formation. Upon gravitationally scattering planetesimal debris, planets migrate.

Tilting Jupiter (a bit) and Saturn (a lot) During Planetary Migration [PDF]
, 2015 We study the effects of planetary late migration on the gas giants obliquities. We consider the planetary instability models from Nesvorny & Morbidelli (2012), in which the obliquities of Jupiter and Saturn can be excited when the spin-orbit resonances ...

TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain
The Astronomical Journal, 2023 Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMRs). Dynamical evolution over time could disrupt the delicate resonant configuration. We present TOI-1136, a 700 ±

Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets
The Astrophysical Journal, 2023 Disk solids are critical in many planet formation processes; however, their effect on planet migration remains largely unexplored. Here we assess this important issue for the first time by building on the systematic measurements of dust torques on an ...

A Role of Proto-Accretion Disk Heating Proto-Planets to Evaporation [PDF]
Journal of Astronomy and Space Sciences, 2002 We study a role of the proto-accretion disk during the formation of the planetary system, which is motivated with recent X-ray observations. There is an observational correlation of the mass of extrasolar planets with their orbital period, which also ...

Toward predictive scenarios of planetary migration
, 2008 La détection récente des exoplanètes a fourni un formidable laboratoire d'expérimentation des théories de formation et d'évolution planétaire. Un résultat troublant est la proportion de planètes géantes situées plus près de leur étoile que ne l'est Mercure de notre Soleil! Si, comme il est admis, ces planètes se sont formées à plus grande distance de l'
