spaceweb@oulu.fi - last update: 30 April 1997, 1000 UT (RR) . In the magnetospheric physics, the ballooning mode instability (BMI) is a disturbance of the equilibrium between outward directed forces caused by the particle pressure and the curvature drift on one hand and inward directed forces exerted by the tangential stress of the field lines on the other hand (e.g., Hameiri et al., ... For recent references on ballooning instability, see, e.g., Liu (1997). ... 102 , 4927-4931, 1997. ...
SINGULAR POINTS IN THE SOLAR CHROMOSPHERE . ... In the structure of the solar chromosphere, containing information on the configuration of the magnetic field, we have found and identified all the main types of the singular points ( see Fig. 1 ), which are known as inherent features of the 2-D vector field. ... The main types of the singular points are the node, the focus, the center, and the saddle. ... Singular point of the focus type in the solar chromosphere. ...

Abstract -- Calculations are performed for the circular polarization of maser radiation from a turbulent, Keplerian disk that is intended to represent the sub-parsec disk at the nucleus of the galaxy NGC4258. ... This turbulence, along with the Keplerian velocity gradients and the blending of the three hyperfine components to form the 6 16 --5 32 masing transition of water, are key ingredients in determining the appearance of the polarized spectra that are calculated. ...

. The various stages encountered during the collapse of a fragmenting supermassive star. Each panel shows the density distribution in the equatorial plane. The star is so rapidly spinning that the configuration at the onset of the collapse (upper left panel) is quasi-toroidal (the maximum density is off-centered thus producing a ring of maximum density). The simulation ends after the black hole has settled (lower right panel). Christian Reisswig/Caltech

... The Russian TESIS/ CORONAS-PHOTON Solar Observatory, which has been working in orbit since January 30th, 2009, has photographed one of the most important events in the build up to the upcoming solar cycle - the formation of our star's new southern belt of activity. The first magnetic fields of the new cycle in the southern hemisphere appeared on the Sun's surface on May 23-24th. ...
