EUV SpectroPhotometer (ESP) in Extreme Ultraviolet Variability Experiment (EVE): Algorithms and Calibrations
Leonid Didkovsky, Darrell Judge, Seth Wieman +2
The Extreme ultraviolet SpectroPhotometer (ESP) is one of five channels of the Extreme ultraviolet Variability Experiment (EVE) onboard the NASA Solar Dynamics Observatory (SDO). T…
A Sensitivity Study of the Enceladus Torus
B. L. Fleshman, P. A. Delamere, F. Bagenal
We have developed a homogeneous model of physical chemistry to investigate the neutral-dominated, water-based Enceladus torus. Electrons are treated as the summation of two isotrop…
The Intensity Profile of the Solar Supergranulation
N. J. Goldbaum, M. P. Rast, I. Ermolli +2
We have measured the average radial (cell center to network boundary) profile of the continuum intensity contrast associated with supergranular flows using data from the Precision…
X-ray Point Sources and Radio Galaxies in Clusters of Galaxies
Quyen N. Hart, John T. Stocke, Eric J. Hallman
Using Chandra imaging spectroscopy and VLA L-band maps, we have identified radio galaxies at P(1.4 GHz) >= 3x10^{23} W Hz^{-1} and X-ray point sources (XPSs) at L(0.3-8 keV) >= 10^…
Accretion Rates of Planetesimals by Protoplanets Embedded in Nebular Gas
Takayuki Tanigawa, Keiji Ohtsuki
When protoplanets growing by accretion of planetesimals have atmospheres, small planetesimals approaching the protoplanets lose their energy by gas drag from the atmospheres, which…
Three years of Ulysses dust data: 2005 to 2007
Harald Krüger, V. Dikarev, B. Anweiler +16
The Ulysses spacecraft has been orbiting the Sun on a highly inclined ellipse since it encountered Jupiter in February 1992. Since then it made almost three revolutions about the S…
Galileo dust data from the jovian system: 2000 to 2003
Harald Krüger, D. Bindschadler, S. F. Dermott +17
The Galileo spacecraft was orbiting Jupiter between Dec 1995 and Sep 2003. The Galileo dust detector monitored the jovian dust environment between about 2 and 370 R_J (jovian radiu…
Calculation of the Solar UV/EUV Spectrum in Spherical Symmetry
Margit Haberreiter, Juan Fontenla
We present work in progress concerning spectral synthesis calculations of the solar UV/EUV in spherical symmetry carried out with the Solar Radiation Physical Modeling (SRPM) proje…
Tidal Limits to Planetary Habitability
Rory Barnes, Brian Jackson, Richard Greenberg +1
The habitable zones of main sequence stars have traditionally been defined as the range of orbits that intercept the appropriate amount of stellar flux to permit surface water on a…
Metal-Free Gas Supply at the Edge of Reionization: Late-Epoch Population III Star Formation
Michele Trenti, Massimo Stiavelli, Michael Shull
While the average metallicity of the intergalactic medium rises above Z~10^{-3} Zsun by the end of the reionization, pockets of metal-free gas can still exist at later times. We qu…
Planet-planet scattering in planetesimal disks
Sean N. Raymond, Philip J. Armitage, Noel Gorelick
We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate th…
Finding the best proxies for the solar UV irradiance
T. Dudok de Wit, M. Kretzschmar, J. Lilensten +1
Solar UV emission has a profound impact on the upper terrestrial atmosphere. Because of instrumental constraints, however, solar proxies often need to be used as substitutes for th…
Constraints on the High-l Power Spectrum of Millimeter-wave Anisotropies from APEX-SZ
C. L. Reichardt, O. Zahn, P. A. R. Ade +27
We present measurements of the angular power spectrum of millimeter wave anisotropies with the APEX-SZ instrument. APEX-SZ has mapped 0.8 square degrees of sky at a frequency of 15…
Straight Line Orbits in Hamiltonian Flows
J. E. Howard, J. D. Meiss
We investigate periodic straight-line orbits (SLO) in Hamiltonian force fields using both direct and inverse methods. A general theorem is proven for natural Hamiltonians quadratic…
Stability of additional planets in and around the habitable zone of the HD 47186 Planetary System
Ravi kumar Kopparapu, Sean N. Raymond, Rory Barnes
We study the dynamical stability of an additional, potentially habitable planet in the HD 47186 planetary system. Two planets are currently known in this system: a "hot Neptune" wi…
Multi-frequency imaging of the galaxy cluster Abell 2163 using the Sunyaev-Zel'dovich Effect
M. Nord, K. Basu, F. Pacaud +30
We used the APEX-SZ and LABOCA bolometer cameras on the APEX telescope to map the decrement of the Sunyaev-Zeldovich effect at 150 GHz and the increment at 345 GHz toward the galax…
Radiation pressure and absorption in AGN: results from a complete unbiased sample from Swift
A. C. Fabian, R. V. Vasudevan, R. F. Mushotzky +1
Outward radiation pressure can exceed the inward gravitational pull on gas clouds in the neighbourhood of a luminous Active Galactic Nucleus (AGN). This creates a forbidden region…
Influence of the Conversion Layer on the Dispersion Relation of Waves in the Solar Atmosphere
M. Haberreiter, W. Finsterle
Observations carried out with the Magneto-Optical Filter at Two Heights (MOTH) experiment show upward-traveling wave packets in magnetic regions with frequencies below the acoustic…
