"Properties of magnetic reconnection at the Earth's magnetopause: recent multipoint observations."
|
Magnetic reconnection is the universal process responsible for mixing and acceleration of plasma of different origins. In magnetospheric research, this process to a great extent defines solar wind-magnetosphere coupling and the subsequent dynamics of plasma inside the system. However, the physical processes responsible for initiating reconnection and the spatial and temporal properties of magnetic reconnection are still poorly understood. In this talk we will discuss the characteristics of the magnetic reconnection at the magnetopause between the Interplanetary Magnetic Field (IMF) and terrestrial field lines, including time variations, location and stability, based on analysis of data coming from multi-satellite missions. We will talk about how we can use in-situ plasma and field measurements inside different regions of the dayside magnetosphere to deduce information about reconnection. We will then discuss recent results on large-scale reconnection geometry at the magnetopause, its properties, and subsequent dynamics of the magnetosphere for different IMF conditions.
