Role of solar flare index in long term modulation of cosmic ray intensity [PDF]

Recently, the importance of the occurrence of solar flares in the long-term modulation of cosmic ray intensity has been re-emphasized. For this purpose, the data of solar flares have been used from various publications, such as Solar Geophysical Data ...

Plasma heating in the very early and decay phases of solar flares

, 2011
In this paper we analyze the energy budgets of two single-loop solar flares under the assumption that non-thermal electrons are the only source of plasma heating during all phases of both events.

Radiative Response to Large Decline in Anthropogenic Emissions From China Between 2008 and 2016 Is Modified by Simultaneous Biomass Burning Emission Changes

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.
Abstract The recent large reduction in anthropogenic aerosol emissions across China has improved China's air quality but has potential consequences for climate forcing. This sharp reduction in anthropogenic emissions has occurred against a background influenced by changing regional biomass burning emissions over a similar period of time.

Super active regions and production of major solar flares [PDF]

The success of imaging detectors with small fields of veiw such as HXIS or P/OF (Pinhole/Occulter Facility) depends heavily on pointing to the right place at the right time.

The flaring and quiescent components of the solar corona

, 2008
The solar corona is a template to understand stellar activity. The Sun is a moderately active star, and its corona differs from active stars: active stellar coronae have a double-peaked EM(T) with the hot peak at 8-20 MK, while the non flaring solar ...

The Periodic and Temporal Behaviors of Solar X-Ray Flares in Solar Cycles 23 and 24

Astrophysical Journal, 2019
The recent solar cycles 23 and 24 are thought to be unusually quiet with more prolonged periods. Both sunspot groups and solar soft X-ray (SXR) flares show a decline in numbers comparable to cycles 21 and 22.

Stellar flares [PDF]

Living Reviews in Solar Physics
Magnetic storms on stars manifest as remarkable, randomly occurring changes of the luminosity over durations that are tiny in comparison to the normal evolution of stars.

Solar flares with and without SOHO/LASCO coronal mass ejections and type II shocks

, 2010
We analyse of a set of radio rich (accompanied by type IV or II bursts) solar flares and their association with SOHO/LASCO Coronal Mass Ejections in the period 1998 2000. The intensity, impulsiveness and energetics of these events are investigated.
