Heating in an Extended Accretion Disk Corona along the Z-Pattern in Cyg X-2
N. S. Schulz, D. P. Huenemoerder, L. Ji +3
We observed at very high spectral resolution the prototype Z-source Cyg x-2 twice along its entire X-ray spectral variation pattern. In this preliminary analysis we find an extende…
Photometric properties of resolved and unresolved magnetic elements
Serena Criscuoli, Mark Rast
We investigate the photometric signature of magnetic flux tubes in the solar photosphere. We developed two dimensional, static numerical models of isolated and clustered magnetic f…
Science with ASKAP - the Australian Square Kilometre Array Pathfinder
S. Johnston, R. Taylor, M. Bailes +47
[ABRIDGED VERSION] The future of cm and m-wave astronomy lies with the Square Kilometre Array (SKA), a telescope under development by a consortium of 17 countries. The SKA will be…
New Observations and a Possible Detection of Parameter Variations in the Transits of Gliese 436b
Jeffrey L. Coughlin, Guy S. Stringfellow, Andrew C. Becker +3
We present ground-based observations of the transiting Neptune-mass planet Gl 436b obtained with the 3.5-meter telescope at Apache Point Observatory and other supporting telescopes…
Cluster Abell 520: a perspective based on member galaxies. A cluster forming at the crossing of three filaments?
M. Girardi, R. Barrena, W. Boschin +1
The connection of cluster mergers with the presence of extended, diffuse radio sources in galaxy clusters is still debated. An interesting case is the rich, merging cluster Abell 5…
A dynamical perspective on additional planets in 55 Cancri
Sean N. Raymond, Rory Barnes, Noel Gorelick
Five planets are known to orbit the star 55 Cancri. The recently-discovered planet f at 0.78 AU (Fischer et al. 2008) is located at the inner edge of a previously-identified stable…
