Archimedean Spiral Distribution of Energetic Particles in Earth's Inner Radiation Belt
Autor: Weiqin Sun, Jian Yang, Wenrui Wang, Jun Cui, Frank Toffoletto, Chao Yue, Matina Gkioulidou, J. Andrew Gerrard
Publikováno v: Geophysical Research Letters, Vol 51, Iss 4, Pp n/a-n/a (2024)
Abstract Archimedean spirals are common in various fields such as biology, engineering, astronomy, and space physics. Here we report the discovery of patterns resembling the general Archimedean spirals in particle distributions in the Earth radiation

RCM modeling of bubble injections into the inner magnetosphere: geosynchronous orbit and the ionospheric responses
Autor: Sina Sadeghzadeh, Jian Yang, Frank Toffoletto, Richard Wolf, Ameneh Mousavi, Chih-Ping Wang
Publikováno v: Frontiers in Astronomy and Space Sciences, Vol 10 (2023)
Introduction: Accurate characterization of the plasma sheet source population in the ring current region and its outer boundary at geosynchronous orbit is crucial for understanding the dynamics of the Earth’s magnetosphere. The interaction between

Origin of Dawnside Subauroral Polarization Streams During Major Geomagnetic Storms
Autor: Dong Lin, Wenbin Wang, Viacheslav G. Merkin, Chaosong Huang, Meers Oppenheim, Kareem Sorathia, Kevin Pham, Adam Michael, Shanshan Bao, Qian Wu, Yongliang Zhang, Michael Wiltberger, Frank Toffoletto, John Lyon, Jeffrey Garretson
Publikováno v: AGU Advances, Vol 3, Iss 4, Pp n/a-n/a (2022)
Abstract Solar eruptions cause geomagnetic storms in the near‐Earth environment, creating spectacular aurorae visible to the human eye and invisible dynamic changes permeating all of geospace. Just equatorward of the aurora, radars and satellites o

Subauroral polarization streams (SAPS): Intrinsic response of geospace during storm time
Autor: Dong Lin, Wenbin Wang, Viacheslav Merkin, Michael Wiltberger, Kareem Sorathia, Kevin Pham, Shanshan Bao, Adam Michael, Xueling Shi, Chaosong Huang, Qian Wu, Yongliang Zhang, Meers Oppenheim, Frank Toffoletto, John Lyon, Jeffrey Garretson, Brian Anderson
Subauroral polarization streams (SAPS) typically refer to an enhanced westward plasma flow channel in the duskside subauroral ionosphere. SAPS overlap with the low-latitude part of downward Region-2 field-aligned currents (FACs). The relatively low s

The Role of Diffuse Electron Precipitation in the Formation of Subauroral Polarization Streams
Autor: Shanshan Bao, Kevin Pham, Viacheslav Merkin, Dong Lin, Brian J. Anderson, Wenbin Wang, A. Michael, Kareem A. Sorathia, X. Shi, J. Garretson, John G. Lyon, Frank Toffoletto, Michael Wiltberger
Publikováno v: Journal of Geophysical Research: Space Physics. 126
The role of diffuse electron precipitation in forming subauroral polarization streams (SAPS) is investigated with the Multiscale Atmosphere-Geospace Environment (MAGE) model. Diffuse precipitation ...

The Role of Mesoscale Plasma Sheet Dynamics in Ring Current Formation
Autor: Viacheslav Merkin, A. Y. Ukhorskiy, J.G. Lyon, Kareem A. Sorathia, D. L. Turner, Frank Toffoletto, J. Garretson, A. Michael, Matina Gkioulidou
Publikováno v: Frontiers in Astronomy and Space Sciences, Vol 8 (2021)
During geomagnetically active periods ions are transported from the magnetotail into the inner magnetosphere and accelerated to energies of tens to hundreds of keV. These energetic ions, of mixed composition with the most important species being H+ a
