Magnetopause and Boundary Layer
Space Science Reviews, 2005A brief overview is given of our present knowledge, observational and theoretical, of the structure of the magnetopause and the adjoining plasma boundary layer. Particular attention is given to the relationship between these electromagnetic and plasma structures on the front lobe of the magnetosphere and the magnetic field reconnection process.

Deriving the Magnetopause Position from the Soft X‐Ray Image by Using the Tangent Fitting Approach
Journal of Geophysical Research: Space Physics, 2020Imaging is one of the essential techniques to observe astronomical structures. While analyzing the observed images, it is a challenge in many scientific fields to reconstruct the 3‐D structures from 2‐D image(s).

Radiation Measurements, 1999
Abstract A review of empirical data-based models of the magnetopause and a comparative analysis are given with special attention to the dynamics of the dayside boundary. Recently different research groups have presented new magnetopause models as an alternative to the model of Roelof and Sibeck (1993, J. Geophys. Res. 94, 15, 125).

Dayside magnetopause reconnection
Journal of Geophysical Research: Space Physics, 1985The Petschek model of magnetic field line reconnection is generalized for magnetopause‐like conditions to enable a comparison of data and theory. The two‐dimensional, compressible MHD model considered reveals four discontinuities which are necessary to match the different magnetic fields and plasma parameters inside and outside the magnetopause.

Magnetic field data from the Goddard Space Flight Center magnetometer experiment on board Ogo 5 are analyzed by the minimum-variance technique for two magnetopause crossings, believed to provide the best evidence presently available of magnetopause rotational discontinuities. Approximate agreement with predictions from MHD and first-order orbit theory

Abstract Five closely spaced magnetic field directional discontinuities observed by Voyager 1 late on 2 March 1979 are analyzed using a variance technique. These discontinuities showed magnetic field signatures characteristic of magnetopause crossings occurring periodically at ≈ 36 min intervals but without dramatic changes in the low energy ( 5 ...

Compressible magnetopause reconnection
Journal of Geophysical Research, 1977A fluid model is analyzed which describes the process of magnetic field merging in a geometry where a compressible magnetized plasma impinges upon a uniform vacuum magnetic field. This two-dimensional model is of the type first proposed by Petschek and co-workers more than a decade ago.

Evidence of Electron Acceleration at a Reconnecting Magnetopause
Geophysical Research Letters, 2019It is still unknown nowadays whether magnetic reconnection—a process occurring both in the magnetotail and at the magnetopause—can intrinsically accelerate energetic electrons.
