International audience; Mapping solar wind plasma back to its source is often achieved using the 'two-step ballistic backmapping' method. Solar wind observations are mapped through the heliosphere to the edge of a PFSS model, by assuming a constant s

Evolving Solar Wind Flow Properties of Magnetic Inversions Observed by Helios

Autor: Mike Lockwood, Robert T. Wicks, Mathew J. Owens, Allan R. Macneil

In its first encounter at solar distances as close as r = 0.16AU, Parker Solar Probe (PSP) observed numerous local reversals, or inversions, in the heliospheric magnetic field (HMF), which were accompanied by large spikes in solar wind speed. Both so

This is the second in a series of papers that investigate the semi-annual, annual and Universal Time (UT) variations in the magnetosphere. We present a varied collection of empirical results that can be used to constrain theories and modelling of the

Radial Evolution of Inverted Heliospheric Magnetic Field Between 0.3 and 1 AU

Autor: Sarah Bentley, Matthew Lang, Allan R. Macneil, Robert T. Wicks, Mike Lockwood, Mathew J. Owens

Local inversions, or ‘switchbacks’, in the heliospheric magnetic field (HMF) have recently been identified as prominent features in the inner heliosphere through observations by Parker Solar Probe. These inversions coincide with spikes in radial

Signatures of Coronal Loop Opening via Interchange Reconnection in the Slow Solar Wind at 1 AU

Autor: Mathew J. Owens, David Stansby, Allan R. Macneil, Mike Lockwood

Publikováno v: Solar Physics. 295

The opening of closed magnetic loops via reconnection with open solar flux, so called “interchange reconnection”, is invoked in a number of models of slow solar wind release. In the heliosphere, this is expected to result in local switchbacks or
