Kink oscillations of solar coronal loops
A catalog of kink oscillations of solar coronal loops, which spans during almost all of solar cycle 24, is presented. The catalog is based on the observations made in the... -
Small-scale magnetic flux ropes in the solar wind
We have developed a new automated small-scale magnetic flux ropes (SSMFR) detection algorithm based on the Grad-Shafranov (GS) reconstruction technique. We have applied this... -
