The role of chaotic resonances in the solar system
N. Murray, M. Holman
Our understanding of the Solar System has been revolutionized over the past decade by the finding that the orbits of the planets are inherently chaotic. In extreme cases, chaotic m…
Chaos in the Solar System
M. Lecar, F. Franklin, M. Holman +1
The physical basis of chaos in the solar system is now better understood: in all cases investigated so far, chaotic orbits result from overlapping resonances. Perhaps the clearest…
HST STIS Observations of PG 0946+301: the Highest Quality UV Spectrum of a BALQSO
Nahum Arav, Martijn de Kool, Kirk T. Korista +16
We describe deep (40 orbits) HST/STIS observations of the BALQSO PG 0946+301 and make them available to the community. These observations are the major part of a multi-wavelength c…
Are Stars with Planets Polluted?
N. Murray, B. Chaboyer
We compare the metallicities of stars with radial velocity planets to the metallicity of a sample of field dwarfs. We confirm recent work indicating that the stars-with-planet samp…
Transport of Magnetic Fields in Convective, Accreting Supernova Cores
Christopher Thompson, Norman Murray
We consider the amplification and transport of a magnetic field in the collapsed core of a massive star, including both the region between the neutrinosphere and the shock, and the…
Eccentricity Evolution of Resonant Migrating Planets
N. Murray, M. Paskowitz, M. Holman
We examine the eccentricity evolution of a system of two planets locked in a mean motion resonance, in which the outer planet loses energy and angular momentum. The sink of energy…
