Chromospheric Jets and Their Properties [PDF]

open access: yesIranian 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]

open access: yesSerbian 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

open access: yesThe 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.

Energy Budget in the Solar Corona

open access: yesThe Astrophysical Journal, 2023
This paper addresses the first direct investigation of the energy budget in the solar corona. Exploiting joint observations of the same coronal plasma by Parker Solar Probe and the Metis coronagraph aboard Solar Orbiter and the conserved equations for ...

Investigating Coronal Holes and CMEs as Sources of Brightness Depletion Detected in PSP/WISPR Images

open access: yesThe Astrophysical Journal, 2023
The Parker Solar Probe (PSP) mission provides a unique opportunity to observe the solar corona from distances below 20 R _☉ . In this work, we utilize white light images from the Wide-field Imager for Solar PRobe aboard the PSP from solar encounters 10 ...

EUV imaging and spectroscopy for improved space weather forecasting

open access: yesJournal of Space Weather and Space Climate, 2020
Accurate predictions of harmful space weather effects are mandatory for the protection of astronauts and other assets in space, whether in Earth or lunar orbit, in transit between solar system objects, or on the surface of other planetary bodies. Because

Coronal spectral diagnostics: The coronal solar magnetism observatory (COSMO)

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The Need: Understanding and predicting the major phenomena taking place in the solar corona, such as flares and Coronal Mass Ejections (CMEs), the heating and evolution of the solar atmosphere, and the acceleration of the solar wind, are fundamental ...

Slow solar wind acceleration through the middle corona: Spacecraft radio studies

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The “Middle Corona”, defined by recent consensus as the region spanning 1.5–6 solar radii (R⊙, heliocentric), is an important zone through which several structural and dynamic changes occur in coronal streamer regions. Among these is a regime change from
