Discovery of underground argon with low level of radioactive 39Ar and possible applications to WIMP dark matter detectors
C. Galbiati, R. Purtschert
We report on the first measurement of 39Ar in argon from underground natural gas reservoirs. The gas stored in the US National Helium Reserve was found to contain a low level of 39…
Satellite Observations of Separator Line Geometry of Three-Dimensional Magnetic Reconnection
C. J. Xiao, X. G. Wang, Z. Y. Pu +14
Detection of a separator line that connects magnetic nulls and the determination of the dynamics and plasma environment of such a structure can improve our understanding of the thr…
A Constant Spectral Index for Sagittarius A* During Infrared/X-ray Intensity Variations
S. D. Hornstein, K. Matthews, A. M. Ghez +5
We report the first time-series of broadband infrared (IR) color measurements of Sgr A*, the variable emission source associated with the supermassive black hole at the Galactic Ce…
Dynamics and planet formation in/around binaries
Francesco Marzari, Philippe Thebault, Steven Kortenkamp +1
We study to which extent planetesimal accretion is affected by the perturbing presence of a compagnon star. We concentrate on one crucial parameter: the distribution of encounter v…
Detailed Models of super-Earths: How well can we infer bulk properties?
Diana Valencia, Dimitar D. Sasselov, Richard J. O'Connell +1
The field of extrasolar planets has rapidly expanded to include the detection of planets with masses smaller than that of Uranus. Many of these are expected to have little or no hy…
Dynamical Complexity, Intermittent Turbulence, Coarse-Grained Dissipation, Criticality and Multifractal Processes
Tom Chang, Cheng-chin Wu
The ideas of dynamical complexity induced intermittent turbulence by sporadic localized interactions of coherent structures are discussed. In particular, we address the phenomenon…
