Magnetic Topology of Coronal Hole Linkages
magnetic topology—Sun corona—Sun solar wind—Sun NASA/GSFC
2010/11/9
In recent work, Antiochos and coworkers argued that the boundary between the open and closed field regions on the Sun can be extremely complex with narrow corridors of open flux connecting seemingly d...
Homologous Flares and Magnetic Field Topology in Active Region NOAA 10501 on 20 November 2003
Active Regions Magnetic Fields Flares Dynamics Flares Relation
2010/11/11
We present and interpret observations of two morphologically homologous flares that occurred in active region (AR) NOAA 10501 on 20 November 2003. Both flares displayed four homologous H ribbons and ...
Topology of large scale structure as test of modified gravity
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The genus of the iso-density contours is a robust measure of the topology of large-scale structure, and relatively insensitive to galaxies biasing and redshift-space distortions. We show that the grow...
We present results on the magnetic field topology in a pulsed radiative jet.For initially helical magnetic fields and perio dic velo city variations, we find thatthe magnetic field alternates along th...
