Incorporation of a Late-forming Chondrule into Comet Wild 2
R. C. Ogliore, G. R. Huss, K. Nagashima +6
We report the petrology, O isotopic composition, and Al-Mg isotope systematics of a chondrule fragment from the Jupiter-family comet Wild 2, returned to Earth by NASA's Stardust mi…
Investigation of the Formation and Separation of An EUV Wave from the Expansion of A Coronal Mass Ejection
X. Cheng, J. Zhang, O. Olmedo +3
We address the nature of EUV waves through direct observations of the formation of a diffuse wave driven by the expansion of a coronal mass ejection (CME) and its subsequent separa…
Incorporating Kinetic Physics into a Two-Fluid Solar-Wind Model with Temperature Anisotropy and Low-Frequency Alfven-Wave Turbulence
Benjamin D. G. Chandran, Timothy J. Dennis, Eliot Quataert +1
We develop a 1D solar-wind model that includes separate energy equations for the electrons and protons, proton temperature anisotropy, collisional and collisionless heat flux, and…
Supergiant X-ray binaries observed by Suzaku
A. Bodaghee, J. A. Tomsick, J. Rodriguez +4
Suzaku observations are presented for the high-mass X-ray binaries IGR J16207-5129 and IGR J17391-3021 (=XTE J1739-302). For IGR J16207-5129, we provide the first X-ray broadband (…
Statistically-derived flaring chromospheric-coronal density structure from non-thermal X-ray observations of the Sun
Pascal Saint-Hilaire, Sam Krucker, Robert P. Lin
For the first time, we have used RHESSI's spatial and energy resolution to determine the combined chromospheric and coronal density profile of the flaring solar atmosphere in a sta…
The x-ray detectability of electron beams escaping from the sun
Pascal Saint-Hilaire, Sam Krucker, Steven Christe +1
We study the detectability and characterization of electron beams as they leave their acceleration site in the low corona toward interplanetary space through their nonthermal X-ray…
X-ray emission from the base of a current sheet in the wake of a CME
Pascal Saint-Hilaire, Sam Krucker, Robert P. Lin
Following a CME which started on 2002 November 26, RHESSI, the Ramaty High Energy Solar Spectroscopic Imager, observed for 12 hours an X-ray source above the solar limb, at altitud…
A Statistical Survey of Hard X-ray Spectral Characteristics of Solar Flares with Two Footpoints
Pascal Saint-Hilaire, Sam Krucker, Robert P. Lin
Using RHESSI data, we have analyzed some 172 hard X-ray peaks during 53 solar flares which exhibited a double-footpoint structure. Fitting both footpoints with power-laws, we find…
Allen Telescope Array Multi-Frequency Observations of the Sun
Pascal Saint-Hilaire, Gordon J. Hurford, Garrett Keating +2
We present the first observations of the Sun with the Allen Telescope Array (ATA). We used up to six frequencies, from 1.43 to 6 GHz, and baselines from 6 to 300 m. To our knowledg…
Comparison of the Diffuse Halpha and FUV Continuum Backgrounds: On the Origins of the Diffuse Halpha Background
Kwang-Il Seon, Adolf Witt, Il-Joong Kim +4
We compare the diffuse H map of our Galaxy with the FUV (1370-1710Å) continuum map. The H intensity correlates well with the FUV intensity. The H/FUV intensity ratio incre…
A Suzaku View of Cyclotron Line Sources and Candidates
K. Pottschmidt, S. Suchy, E. Rivers +20
Seventeen accreting neutron star pulsars, mostly high mass X-ray binaries with half of them Be-type transients, are known to exhibit Cyclotron Resonance Scattering Features (CRSFs)…
Dynamic Coupling of Convective Flows and Magnetic Field during Flux Emergence
Fang Fang, Ward Manchester, William P. Abbett +1
We simulate the buoyant rise of a magnetic flux rope from the solar convection zone into the corona to better understand the energetic coupling of the solar interior to the corona.…
The Allen Telescope Array Search for Electrostatic Discharges on Mars
Marin M. Anderson, Andrew P. V. Siemion, William C. Barott +4
The Allen Telescope Array was used to monitor Mars between 9 March and 2 June 2010, over a total of approximately 30 hours, for radio emission indicative of electrostatic discharge…
Pressure balance at the magnetopause: Experimental studies
A. V. Suvorova, A. V. Dmitriev
The pressure balance at the magnetopause is formed by magnetic field and plasma in the magnetosheath, on one side, and inside the magnetosphere, on the other side. In the approach…
Properties of Energetic Ions in the Solar Atmosphere from γ -Ray and Neutron Observations
Nicole Vilmer, Alec L. MacKinnon, Gordon J. Hurford
Gamma-rays and neutrons are the only sources of information on energetic ions present during solar flares and on properties of these ions when they interact in the solar atmosphere…
Deducing Electron Properties From Hard X-Ray Observations
E. P. Kontar, J. C. Brown, A. G. Emslie +11
X-radiation from energetic electrons is the prime diagnostic of flare-accelerated electrons. The observed X-ray flux (and polarization state) is fundamentally a convolution of the…
Energy Release and Particle Acceleration in Flares: Summary and Future Prospects
R. P. Lin
RHESSI measurements relevant to the fundamental processes of energy release and particle acceleration in flares are summarized. RHESSI's precise measurements of hard X-ray continuu…
Decorrelation Times of Photospheric Fields and Flows
