The fourth data release of the Sloan Digital Sky Survey
This paper describes the Fourth Data Release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through 2004 June. The data release includes five-band photometric dataExpand

The Structural evolution of substructure
We investigate the evolution of substructure in cold dark matter (CDM) halos using N-body simulations of tidal stripping of substructure halos within a static host potential. We find that halosExpand

The Formation and Extent of the Solar System Comet Cloud
The formation of the solar system comet cloud and its subsequent evolution over an interval equal to the age of the solar system are simulated. Assuming that the comets formed in the outer planetaryExpand

We have performed a high mass and force resolution simulation of an idealized galaxy forming from dissipational collapse of gas embedded in a spherical dark matter halo. The simulation includes starExpand

Implications of Stellar Migration for the Properties of Galactic Disks
Stars in disks of spiral galaxies are usually assumed to remain roughly at their birth radii. This assumption is built into decades of modeling of the evolution of stellar populations in our ownExpand

Making other earths: dynamical simulations of terrestrial planet formation and water delivery
We present results from 44 simulations of late stage planetary accretion, focusing on the delivery of volatiles (primarily water) to the terrestrial planets. Our simulations include both planetaryExpand

The long-term evolution of orbits in the solar system: A mapping approach
Abstract We derive a mapping that approximates the restricted circulat three-body problem (Sun, planet, test particle) when the eccentricity ofr test particle is small and its semimajor axis is closeExpand

Making Galaxies in a Cosmological Context: The Need for Early Stellar Feedback
We introduce the Making Galaxies in a Cosmological Context (MaGICC) program of smoothed particle hydrodynamics (SPH) simulations. We describe a parameter study of galaxy formation simulations of anExpand

A Three Million Year Integration of the Earth's Orbit
The equations of motion of the nine planets and the Earth's spin axis are integrated for 3.05 million years into the past. The equations include the dominant relativistic corrections and correctionsExpand
