Chromospheric Jets and Their Properties [PDF]

Iranian Journal of Astronomy and Astrophysics, 2022
In this study we review solar chromospheric jets and characteristics of them. The chromosphere and transition region are the interface between the solar photosphere and the corona, which plays a key role in the formation and acceleration of the solar ...

Polarization of white-light solar corona and sky polarization effect during total solar eclipse on March 29, 2006 [PDF]

Serbian Astronomical Journal, 2019
Ground-based total solar eclipse observations are still the key method for coronal investigations. The question about its white-light degree of polarization remains unanswered.

Magnetic Reconnection as the Driver of the Solar Wind

The Astrophysical Journal, 2023
We present EUV solar observations showing evidence for omnipresent jetting activity driven by small-scale magnetic reconnection at the base of the solar corona.
