Migration-Induced Architectures of Planetary Systems [PDF]
Origins of Life and Evolution of Biospheres, 2012 The recent increase in number of known multi-planet systems gives a unique opportunity to study the processes responsible for planetary formation and evolution. Special attention is given to the occurrence of mean-motion resonances, because they carry important information about the history of the planetary systems. At the early stages of the evolution,

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.

Metallicity, planetary formation and migration [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 Recent observations show a clear correlation between the probability of hosting a planet and the metallicity of the parent star. Since radial velocity surveys are biased, however, towards detecting planets with short orbital periods, the probability-metallicity correlation could merely reflect a dependence of migration rates on metallicity.

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 ...

Application of recent results on the orbital migration of low mass planets: convergence zones [PDF]
, 2010 Previous models of the combined growth and migration of protoplanets needed large ad hoc reduction factors for the type I migration rate as found in the isothermal approximation.

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 ...

Good Combination of the Rossiter-McLaughlin Measurements and Direct Imaging Observations
EPJ Web of Conferences, 2011 We introduce a novel methodology to distinguish planetary migration mechanisms by a combination of Rossiter-McLaughlin measurements and direct imaging observations.

Migrating microbes and planetary protection
Trends in Microbiology, 2009 Since the dawn of the space age, humans have wrestled with concerns about planetary cross-contamination. Spacecraft launched from Earth can transport hitchhiker microbes to new worlds on both robotic and crewed vehicles. As plans proceed for future life detection and human exploration missions, planetary protection considerations are again uppermost on
