Emission line diagnostics of magnetospheric accretion in young stellar objects
Line emission Stars Accretion Star formation Formation of the accretion flow Stars Magnetic layer
2014/12/9
This thesis seeks to explain the nature of line emission observed in young stellar objects, and to use the lines as diagnostics of the accretion process that is central to star formation. We maintain ...
Spatial Distribution of Seismicity: Relationships with Geomagnetic Z-Component in Geocentric Solar Magnetospheric Coordinate System
Earthquake Occurrence Earthquake Magnitude
2013/3/11
For 173477 epicenters of earthquakes with М ≥ 4.5, which occurred at the globe in 1973-2010, the geomagnetic Z-component in Geocentric Solar Magnetospheric (GSM) coordinate system were evaluated for t...
The Cusp as a Source of Magnetospheric Particles
Satellites plasma the solar wind magnetic sheath origin diamagnetic cavities the dipole field
2017/3/23
Observations made by a number of satellites have shown that plasma of solar wind/magnetosheath origin enters the high altitude polar cusp creating diamagnetic cavities of large dimensions. The Earth's...
Possible Signatures of Magnetospheric Accretion onto Young Giant Planets
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
Magnetospheric accretion is an important process for a wide range of astrophysical systems, and may play a role in the formation of gas giant planets. Extending the formalism describing stellar magnet...
Our intention in this work is to show, by using two different methods, that magnetospheric dynamics reveal low dimensional chaos. In the first method we extend the chaotic analysis for the AE index ti...
