The initial trajectories of eruptive solar prominences     

B. P. Filippov 《Astronomy Reports》2016,60(3):356-365

Trajectories of eruptive prominences are compared with the shapes of coronal neutral surfaces calculated in a potential approximation using photospheric measurements. Space-based Solar Dymamics Observatory and STEREO observations carried out at different viewing angles enable a precise determination of a prominence’s position at successive times during its eruption. In the initial segments of their trajectories, eruptive prominences move along neutral surfaces (B_r = 0) of the potential coronal magnetic field. This can be used to predict the directions of subsequent coronal mass ejections and to estimate their geoefficiency.  相似文献

Composition and formation settings of the siliceous-volcanogenic complexes of the Nizhneussuriisk segment,Kiselevka-Manoma terrane,West Sikhote Alin     

A. N. Filippov  G. I. Govorov  A. A. Chashchin  T. A. Punina 《Russian Journal of Pacific Geology》2010,4(4):289-303

This paper reports new data on the mineralogical-petrographical composition, genetic types of sedimentary rocks, and geochemical features of the volcanic rocks of the Snarsky area of the Nizhneussuriisk segment of the Kiselevka-Manoma accretionary complex, which is developed on the right bank of the lower reaches of the Ussuri River. The Middle Jurassic-Aptian sedimentary rocks of the area are represented by pelagic radiolarian cherts, semipelagic siliceous-clayey deposits, subordinate shallow limestones, volcanomictic conglomerates, and turbidite sandstones. The basalts of the area are represented by alkaline basalts resembling within-plate ocean-island basalts and N-MORB-type tholeiitic basalts. Rock associations of two physicogeographical and geodynamic settings are distinguished: the pelagic setting with within-plate alkaline volcanic rocks and the hemipelagic one with volcanic edifices of spreading basalts.  相似文献   

Coronal mass ejections and eruptive prominences: Mutual spatial arrangement     

A. V. Lozhechkin  B. P. Filippov 《Astronomy Reports》2004,48(2):145-152

The mutual spatial arrangement of coronal mass ejections and eruptive prominences on the Sun is considered. These phenomena occur on different scales and are observed at different heights above the solar surface. In spite of the presumed causal connection between them, they are often widely separated in position angle at epochs of solar minimum. This means that the motion of a prominence in the corona is not strictly radial and has an appreciable component along the surface. This behavior can be explained in a model of a filament as a magnetic flux rope in equilibrium in the coronal magnetic field. The initial trajectory of the filament is determined by the structure of the global field.  相似文献

Siliceous-clayey rocks of the Jurassic accretionary prism, Khekhtsir Range, Sikhote Alin: Stratigraphy and genesis     

A. N. Filippov  I. V. Kemkin 《Russian Journal of Pacific Geology》2007,1(1):42-60

Lithologic-stratigraphic aspects of siliceous-clayey rocks forming the Khabarovsk terrane of the Jurassic accretionary prism were studied in western spurs of the Bol’shoi Khekhtsir Range on the left side of the Ussuri River (Ussuri-Khekhtsir section). Two defined types of the examined section differ in the composition, age, and origin of their constituting rocks. The northern segment of the section is composed of middle Bajocian red-brown siliceous-tuffaceous silty and olive-gray silty mudstones that accumulated in the hemipelagic domain under the influence of continental provenance. Its southern segment is represented by lower Bathonian olive-gray siliceous mudstones, mudstones barren of any admixtures, and yellowish brown tuffaceous mudstones deposited far away from the continent in waters with abundant radiolarians. It is shown that these rocks are elements of two tectono-stratigraphic complexes that reflect different stages in the accretionary prism formation.  相似文献

Some properties of the joining of solar filaments     

B. P. Filippov 《Astronomy Reports》2011,55(6):541-550

Some possibilities for the reconnection of magnetic-field lines of solar filaments that approach when the photospheric polarity inversion lines change their positions, are discussed. The interaction between filaments depends on their internal properties, which are determined by the filament chirality, or the sign of the helicity of the filament magnetic field. In quadrupolar magnetic configurations, filaments with the same chirality can exchange their halves. Filaments with opposite chirality rupture after the reconnection of the polarity inversion lines, since the two fragments of the different filaments cannot be connected continuously. The morphology and connectivity of the filaments are analyzed using daily Hα filtergrams obtained over the period of maximum activity of the 23rd solar cycle. Examples of alterations of the filament connectivity occuring during the evolution of photospheric fields are presented.  相似文献
