, 2008 Gravitational torques between a planet and gas in the protoplanetary disk result in orbital migration of the planet, and are likely to play an important role in the formation and early evolution of planetary systems. For masses comparable to those of observed giant extrasolar planets, the interaction with the disk is strong enough to form a gap ...

Analytical model of multi-planetary resonant chains and constraints on migration scenarios [PDF]
, 2017 Resonant chains are groups of planets for which each pair is in resonance, with an orbital period ratio locked at a rational value (2/1, 3/2, etc.). Such chains naturally form as a result of convergent migration of the planets in the proto-planetary disk.

The Emergence of Planetary Pediatrics
Children, 2021 Pediatrics has witnessed an evolution from primary care, family-centered care, community pediatrics, social pediatrics and global pediatrics, which has shifted our attention beyond the clinic setting to an appreciation of children in their lived ...

Constraining the orbit of the planet-hosting binary $\tau$ Bo\"otis: Clues about planetary formation and migration. [PDF]
, 2018 The formation of planets in compact or highly eccentric binaries and the migration of hot Jupiters are two outstanding problems in planet formation. The hot Jupiter $\tau$ Boo Ab orbits the primary star in the long-period ($P \gtrsim 1000\,$yr), highly ...

The SOAPS project – Spin-orbit alignment of planetary systems
EPJ Web of Conferences, 2013 The wealth of information rendered by Kepler planets and planet candidates is indispensable for statistically significant studies of distinct planet populations, in both single and multiple systems.

The effect of orbital damping during planet migration on the Inclination and Eccentricity Distributions of Neptune Trojans [PDF]
, 2016 We explore planetary migration scenarios for formation of high inclination Neptune Trojans (NTs) and how they are affected by the planetary migration of Neptune and Uranus. If Neptune and Uranus's eccentricity and inclination were damped during planetary migration, then their eccentricities and inclinations were higher prior and during migration than ...

Comments on "Type II migration strikes back -- An old paradigm for planet migration in discs" by Scardoni et al [PDF]
, 2020 In the conventional view of type II migration, a giant planet migrates inward in the viscous velocity of the accretion disc in the so-call disc-dominate case. Recent hydrodynamic simulations, however, showed that planets migrate with velocities much faster than the viscous one in massive discs.

Migration of planets embedded in a circumstellar disk [PDF]
, 2011 Planetary migration poses a serious challenge to theories of planet formation. In gaseous and planetesimal disks, migration can remove planets as quickly as they form. To explore migration in a planetesimal disk, we combine analytic and numerical approaches. After deriving general analytic migration rates for isolated planets, we use N-body simulations
