pynucastro: A Python Library for Nuclear Astrophysics
Alexander Smith Clark, Eric T. Johnson, Zhi Chen +6
We describe pynucastro 2.0, an open source library for interactively creating and exploring astrophysical nuclear reaction networks. We demonstrate new methods for approximating ra…
Modeling Porous Dust Grains with Ballistic Aggregates. II. Light Scattering Properties
Yue Shen, B. T. Draine, Eric T. Johnson
We study the light scattering properties of random ballistic aggregates constructed in Shen et al. (Paper I). Using the discrete-dipole-approximation, we compute the scattering pha…
Modeling Porous Dust Grains with Ballistic Aggregates I: Geometry and Optical Properties
Yue Shen, B. T. Draine, Eric T. Johnson
We investigate the scattering and absorption of light by random ballistic aggregates of spherical monomers. We present a general measure for the porosity of an irregular particle.…
Cassini States with Dissipation: Why Obliquity Tides Cannot Inflate Hot Jupiters
Daniel C. Fabrycky, Eric T. Johnson, Jeremy Goodman
Some short-period exoplanets (hot Jupiters) are observed by their transits to have anomalously large radii. It has been suggested that these planets are in a resonance involving pe…
Diffusive Migration of Low-Mass Proto-planets in Turbulent Disks
Eric T. Johnson, Jeremy Goodman, Kristen Menou
Torque fluctuations due to magnetorotational turbulence in proto-planetary disks may greatly influence the migration patterns and survival probabilities of nascent planets. Provide…
SDSS J0903+5028: A New Gravitational Lens
David E. Johnston, Gordon T. Richards, Joshua A. Frieman +22
We report the discovery of a new gravitationally lensed quasar from the Sloan Digital Sky Survey, SDSS J090334.92+502819.2. This object was targeted for SDSS spectroscopy as a Lumi…
