abstract = "Magnetic reconnection in a current sheet is commonly found in
astrophysical plasma environments. If it is often bursty,
releasing magnetic free energy explosively, in planetary
magnetospheres, it instead displays a quasi-steady state in the
solar wind, where the energy is dissipated via slow-mode shocks.
The reason for this difference is elusive. Here we present a
direct observation of bursty and turbulent magnetic reconnection
in the solar wind, with its associated exhausts bounded by a pair
of slow-mode shocks. We infer that the plasma is more efficiently
heated in the magnetic reconnection diffusion region than across
the shocks and that the flow enhancement is much higher in the
exhausts than in the area around the diffusion region. We detected
75 other, similar diffusion-region events in solar wind data
between October 2017 and May 2019, suggesting that bursty
reconnection in the solar wind is more common than previously
thought and actively contributes to solar wind acceleration and
heating.",
