Ultra-high-resolution observations of persistent null-point reconnection in the solar corona
Barczynski, K.; Peter, H.; Chitta, L. P. +21 more
Magnetic reconnection is a key mechanism involved in solar eruptions and is also a prime possibility to heat the low corona to millions of degrees. Here, we present ultra-high-resolution extreme ultraviolet observations of persistent null-point reconnection in the corona at a scale of about 390 km over one hour observations of the Extreme-Ultravio…
Polarisation of decayless kink oscillations of solar coronal loops
Antolin, Patrick; Berghmans, David; Chitta, Lakshmi Pradeep +4 more
Decayless kink oscillations of plasma loops in the solar corona may contain an answer to the enigmatic problem of solar and stellar coronal heating. The polarisation of the oscillations gives us a unique information about their excitation mechanisms and energy supply. However, unambiguous determination of the polarisation has remained elusive. Her…
