Modeling the Near-Surface Shear Layer: Diffusion Schemes Studied With CSS
Kyle Augustson, Mark Rast, Regner Trampedach +1
As we approach solar convection simulations that seek to model the interaction of small-scale granulation and supergranulation and even larger scales of convection within the near-…
Solar Wind Driving of Magnetospheric ULF Waves: Pulsations Driven by Velocity Shear at the Magnetopause
S. G. Claudepierre, S. R. Elkington, M. Wiltberger
We present results from global, three-dimensional magnetohydrodynamic (MHD) simulations of the solar wind/magnetosphere interaction. These MHD simulations are used to study ultra l…
Magnetospheric Cavity Modes Driven by Solar Wind Dynamic Pressure Fluctuations
S. G. Claudepierre, M. Wiltberger, S. R. Elkington +2
We present results from Lyon-Fedder-Mobarry (LFM) global, three-dimensional magnetohydrodynamic (MHD) simulations of the solar wind-magnetosphere interaction. We use these simulati…
Spitzer Mapping of PAHs and H2 in Photodissociation Regions
Brian T. Fleming, Kevin France, Roxana E. Lupu +1
The mid-infrared (MIR) spectra of dense photodissociation regions (PDRs) are typically dominated by emission from polycyclic aromatic hydrocarbons (PAHs) and the lowest pure rotati…
Influence of Hot Plasma Pressure on the Global Structure of Saturn's Magnetodisk
N. Achilleos, P. Guio, C. S. Arridge +4
Using a model of force balance in Saturn's disk-like magnetosphere, we show that variations in hot plasma pressure can change the magnetic field configuration. This effect changes…
Evolution of the Solar Nebula and Planet Growth Under the Influence of Photoevaporation
Tyler R. Mitchell, Glen R. Stewart
The recent development of a new minimum mass solar nebula, under the assumption that the giant planets formed in the compact configuration of the Nice model, has shed new light on…
Radiative emission of solar features in the Ca II K line: comparison of measurements and models
I. Ermolli, S. Criscuoli, H. Uitenbroek +3
We study the radiative emission of various types of solar features, such as quiet Sun, enhanced network, plage, and bright plage regions, identified on filtergrams taken in the Ca…
Physical characteristics and non-keplerian orbital motion of "propeller" moons embedded in Saturn's rings
Matthew S. Tiscareno, Joseph A. Burns, Miodrag Sremčević +8
We report the discovery of several large "propeller" moons in the outer part of Saturn's A ring, objects large enough to be followed over the 5-year duration of the Cassini mission…
Spacecraft charging and ion wake formation in the near-Sun environment
R. E. Ergun, D. M. Malaspina, S. D. Bale +7
A three-dimensional (3-D), self-consistent code is employed to solve for the static potential structure surrounding a spacecraft in a high photoelectron environment. The numerical…
Merging and Clustering of the Swift BAT AGN Sample
Michael Koss, Richard Mushotzky, Sylvain Veilleux +1
We discuss the merger rate, close galaxy environment, and clustering on scales up to a Mpc of the SWIFT BAT hard X-ray sample of nearby (z<0.05), moderate-luminosity active galacti…
The Evolution of the UV Luminosity Function from z ~ 0.75 to z ~ 2.5 using HST ERS WFC3/UVIS Observations
P. A. Oesch, R. J. Bouwens, C. M. Carollo +7
We present UV luminosity functions (LFs) at 1500 Angstrom derived from the HST Early Release Science WFC3/UVIS data acquired over ~50 arcmin^2 of the GOODS-South field. The LFs are…
NLTE solar irradiance modeling with the COSI code
A. I. Shapiro, W. Schmutz, M. Schoell +2
Context. The solar irradiance is known to change on time scales of minutes to decades, and it is suspected that its substantial fluctua- tions are partially responsible for climate…
Spectra and Light Curves of Six Type Ia Supernovae at 0.511 < z < 1.12 and the Union2 Compilation
R. Amanullah, C. Lidman, D. Rubin +42
We report on work to increase the number of well-measured Type Ia supernovae (SNe Ia) at high redshifts. Light curves, including high signal-to-noise HST data, and spectra of six S…
Spitzer mid-infrared spectroscopy of compact symmetric objects: What powers radio-loud active galactic nuclei?
Kyle W. Willett, John T. Stocke, Jeremy Darling +1
We present low- and high-resolution mid-infrared (mid-IR) spectra and photometry for eight compact symmetric objects (CSOs) taken with the Infrared Spectrograph on the Spitzer Spac…
Origin of the Different Architectures of the Jovian and Saturnian Satellite Systems
Takanori Sasaki, Glen R. Stewart, Shigeru Ida
The Jovian regular satellite system mainly consists of four Galilean satellites that have similar masses and are trapped in mutual mean motion resonances except for the outer satel…
Observational Properties of Rotationally Excited Molecular Hydrogen In Translucent Lines of Sight
Adam G. Jensen, Theodore P. Snow, George Sonneborn +1
The {\it Far Ultraviolet Spectroscopic Explorer} ({\it FUSE}) has allowed precise determinations of the column densities of molecular hydrogen ($\Hmol$) in Galactic lines of sight…
The Dust Trail of Comet 67P/Churyumov-Gerasimenko between 2004 and 2006
Jessica Agarwal, Michael Mueller, William T. Reach +3
We report on observations of the dust trail of comet 67P/Churyumov-Gerasimenko (CG) in visible light with the Wide Field Imager at the ESO/MPG 2.2m telescope at 4.7 AU before aphel…
Modeling the Enceladus plume--plasma interaction
B. L. Fleshman, P. A. Delamere, F. Bagenal
We investigate the chemical interaction between Saturn's corotating plasma and Enceladus' volcanic plumes. We evolve plasma as it passes through a prescribed H2O plume using a phys…
