GROUND BASED SUPPORT OF THE SPACE MISSION PARKER PERFORMED WITH UKRAINIAN LOW FREQUENCY RADIO TELESCOPES [PDF]

open access: yesRadio Physics and Radio Astronomy, 2023
Subject and Purpose. The sporadic radio emissions coming from the Sun in a broad frequency range contain a lot of important information concerning the solar corona, parameters of the radio frequency sources therein, and the parameter variations resulting

Self-adaptive integration of photothermal and radiative cooling for continuous energy harvesting from the sun and outer space [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance The sun (∼6,000 K) and outer space (∼3 K) are two natural energy resources for humans. However, most of the approaches of energy harvesting from the sun and rejecting energy to outer space are achieved independently using absorbers and ...

The Sun is less active than other solar-like stars [PDF]

open access: yesScience, 2020
Activity levels of Sun-like stars Magnetic activity on the Sun leads to solar flares, coronal mass ejections, and other space weather that affects Earth. Similar activity on other stars may determine the habitability of any orbiting exoplanets.

Probing the rotation rate of solar active regions: the comparison of methods

open access: yesOpen Astronomy, 2022
Sunspot groups are often used as tracers to probe the differential rotation of the Sun. However, the results on the rotation rate variation obtained by different authors are not always in agreement. The reason for this might be a number of effects.

An ALMA Observation of Time Variations in Chromospheric Temperature of a Solar Plage Region

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Nanoflares and the shock formation of magnetohydrodynamic waves in the solar chromosphere have been considered as key physical mechanisms of the heating of the chromosphere and corona.

The sun as a significant agent provoking earthquakes

open access: yesThe European Physical Journal Special Topics, 2021
In this paper we provide significant evidence that the sun is a principal agent provoking seismic activity. In particular the aim of the studies presented is to examine the possible relation of the coronal hole (CH) driven high speed solar wind streams ...

The Variation of the X-ray Solar Flare’s Time Profile

open access: yesUniverse, 2022
We have studied the variation of the time profile of X-ray emission of solar flares that occurred during the second half of solar cycle 23 (SC 23) and for about the full solar cycle 24 (SC 24) (2002–2018). We define a new index, called the “ratio index” (
