Planetesimals to protoplanets–II. Effect of debris on terrestrial planet formation
methods N-body simulations–methods numerical–Solar system formation–planetary systems formation
<
2015/12/25
In this paper, we extend our numerical method for simulating terrestrial planet formation to include dynamical friction from the unresolved debris component. In the previous work, we implemented a rub...
PLANETESIMALS IN THE PRESENCE OF GIANT PLANET MIGRATION
Accretion accretion disks methods:n-body simulations planetary systems planets and satellites general
<
2015/12/25
We present N-body simulations illustrating how giant planet migration can significantly affect the conditions for the formation of interior terrestrial planets. A giant planet migrating through aswarm...
PLANETESIMALS TO PROTOPLANETS. I. EFFECT OF FRAGMENTATION ON TERRESTRIAL PLANET FORMATION
n-body simulations planetary systems solar system
<
2015/12/25
We present results from a dozen direct N-body simulations of terrestrial planet formation with various initial conditions. In order to increase the realism of our simulations and investigate theeffect...
In his lengthy foreword, astronaut Piers Sellers sets the tone for this beautiful book: "…there are dozens of beautiful coffee table books out there full of Earth images. I should know; I have a stack...
Arc Marine: GIS For a Blue Planet

This interesting and useful manual is meant to provide the background and context for a set of software that assists marine scientists to carry out GIS (Geographical Information System) analysis of mu...
Ebb and Flow: Tides and Life on Our Once and Future Planet
Once and Future Planet Tides and Life
<
2015/7/20
Ebb and Flow: Tides and Life on Our Once and Future Planet is well titled. It tells the story of tides, why they matter, what causes them, and how they have changed over time. The author, Tom Koppel, ...
Long Period Tidal Force Variations and Regularities in Orbital Motion of the Earth-Moon Binary Planet System
Long Period Tidal Force Variations and Regularities Orbital Motion the Earth-Moon Binary Planet System Geophysics
<
2012/5/28
We have studied long period, 206 and 412 day, variations in tidal sea level corresponding to various moon phases collected from five observatories in the Northern and Southern hemispheres. Variations ...
Sundman Stability of Natural Planet Satellites
Hill stability Sundman stability planet satellites
<
2012/2/23
The stability of the motion of the planet satellites is considered in the model of the general three-body problem (Sun-planet-satellite). "Sundman surfaces" are constructed, by means of which the conc...
Second-generation microlensing planet surveys: a realistic simulation
surveys – gravitational lensing: micro – methods: statistical – binaries: general – planetary systems – Galaxy: stellar content
<
2011/10/20
Microlensing surveys, which have discovered about a dozen extrasolar planets to date, have focused on the small minority of high-magnification lensing events, which have a high sensitivity to planet d...
We analyse the chromospherical activity of stars with extrasolar planets and search for a possible correlation between the equivalent width of the core of Ca II K line and orbital parameters of the pl...
Elemental abundance differences in the 16 Cygni binary system: a signature of gas giant planet formation?
Elemental abundance differences signature planet formation
<
2011/10/20
The atmospheric parameters of the components of the 16Cygni binary system, in which the secondary has a gas giant planet detected, are measured accurately using high quality observational data. Abunda...
Application of the Titius-Bode Rule to the 55 Cancri System: Tentative Prediction of a Possibly Habitable Planet
astrobiology— methods: statistical — stars: individual (55 Cnc)— stars: planetary systems
<
2011/10/19
Following the notion that the Titius-Bode rule (TBR) may also be applicable to some extra-solar planetary systems, although this number could be relatively small, it is applied to 55 Cancri, which is ...
Imaging power of multi-fibered nulling telescopes for extra-solar planet characterization

2011/10/13
In this paper are discussed the nulling and imaging properties of monolithic pupil telescopes equipped with a focal plane waveguide array, which could be envisaged as precursor space missions for futu...

<
2011/10/13
We study systems of close orbiting planets evolving under the influence of tidal circularization. It is supposed that a commensurability forms through the action of disk induced migration and orbital ...
