Differences in physical properties of coronal bright points and their ALMA counterparts within and outside coronal holes

This study investigates and compares the physical properties, such as intensity and area, of coronal bright points (CBPs) inside and outside of coronal holes (CHs) using the Atacama Large Millimeter/submillimeter Array (ALM...

To Conception of Sovereign in Coronation Order of Charles IV

Two examples ? royal hall and enthronement in the end of coronation rite ? try to make the important points of Cibulka´s interpretation of the coronation Order of Charles IV deeper. Maybe more exactly: Charles redaction of ...

An Application of the Random Walk Model to Proper Motions of Coronal Bright Points from SDO Data

Atmospheric Imaging Assembly (AIA) images from the Solar Dynamics Observatory (SDO) were used to follow the motions of coronal bright points (CBPs) in the period 1 January - 19 May 2011 with a cadence of 10 minutes. This resulted in...

Interplanetary modeling of ICMEs.

Coronal mass ejections are transient expulsions of solar plasma from the gravitational field of the Sun as seen in white light coronagraph observations. Their interplanetary manifestations are called interplanetary coronal mass ejec...

Dynamics and waves near multiple magnetic null points in reconnection diffusion region

null structures in the diffusion region, the dynamics, and the associated waves. Possible spiral null pair has been identified near the diffusion region. There is a close relation among the null points, the bipola...

A criterion of Gamma-nullness and differentiability of convex and quasiconvex functions

We introduce a criterion for a set to be Gamma-null. Using it we give a shorter proof of the result that the set of points where a continuous convex function on a separable Asplund space is not Frechet differentiable is Gamma-nu...

Emergence of magnetic null points in electro-vacuum magnetospheres of compact objects: The case of a plunging neutron star

We study the possible emergence of magnetic null points which are astrophysically relevant for the processes of magnetic reconnection. While the magnetic reconnection occurs in the presence of plasma and may lead to violent mass eje...
