We present formation simulations of the six Kepler 11 planets. Models assume either in situ or ex situ assembly, the latter with migration, and are evolved to the estimated age of the system, . Models combine detailed calculations of both the gaseous envelope and the condensed core structures, including accretion of gas and solids, of the disk’s viscous and thermal evolution, including photo-evaporation and disk-planet interactions, and of the planet’s evaporative mass loss after disk dispersal…

Combined mass and radius observations have recently revealed many short-period planets a few times the size of Earth but with significantly lower densities. A natural explanation for the low density
An Analytic Criterion for Turbulent Disruption of Planetary Resonances
Mean motion commensurabilities in multi-planet systems are an expected outcome of protoplanetary disk-driven migration, and their relative dearth in the observational data presents an important
Three Super-Earths Transiting the Nearby Star GJ 9827
We report on the discovery of three transiting planets around GJ 9827. The planets have radii of 1.75 ± 0.18, 1.36 ± 0.14, and R⊕, and periods of 1.20896, 3.6480, and 6.2014 days, respectively. The
Yarkovsky and YORP Effects in Dynamics of Small Bodies of the Solar System
In this thesis, we study the influence of non-gravitational perturbations induced by the Yarkovsky/YORP effect and solar radiation pressure (SRP) on the orbital evolution of selected asteroids,
The dehydration of water worlds via atmospheric losses
We present a three-species multi-fluid magnetohydrodynamic model (H+, H2O+, and e−), endowed with the requisite atmospheric chemistry, that is capable of accurately quantifying the magnitude of water
Factoring Origin of Life Hypotheses into the Search for Life in the Solar System and Beyond
TLDR
The relative probability that life could have emerged in environments on early Mars, on the icy moons of Jupiter and Saturn, and also the degree to which prebiotic chemistry could have advanced on Titan are discussed.
New Formation Models for the Kepler-36 System
Formation of the planets in the Kepler-36 system is modeled by detailed numerical simulations according to the core-nucleated accretion scenario. The standard model is updated to include the

Models of the in Situ Formation of Detected Extrasolar Giant Planets
Abstract We present numerical simulations of the formation of the planetary companions to 47 UMa, ρ CrB, and 51 Peg. They are assumed to have formed in situ according to the basic model that a core

We analyze the orbital and mass evolution of planets that undergo runaway gas accretion by means of two- and three-dimensional hydrodynamic simulations. The disk torque distribution per unit disk

We present a Monte Carlo model for the structure of low-mass (total mass <25 M⊕) planetary systems that form by the in situ gravitational assembly of planetary embryos into final planets. Our model

Toward a Deterministic Model of Planetary Formation. I. A Desert in the Mass and Semimajor Axis Distributions of Extrasolar Planets
In an attempt to develop a deterministic theory for planet formation, we examine the accretion of cores of giant planets from planetesimals, gas accretion onto the cores, and their orbital migration.

We study the evolution of planetesimals in evolved gaseous disks that orbit a solar-mass star and harbor a Jupiter-mass planet at a p ≈ 5 ?> AU. The gas dynamics are modeled with a three-dimensional
A reassessment of the in situ formation of close-in super-Earths
Context. A large fraction of stars host one or multiple close-in super-Earth planets. There is an active debate about whether these planets formed in situ or at greater distances from the central
Formation of Giant Planets
This is a descriptive and non-mathematical summary of giant planet formation theories. There are two end-member models, core accretion and disk instability. In the core accretion model, several to
