IMPULSIVITY PARAMETER FOR SOLAR FLARES [PDF]

The Astrophysical Journal, 2016
ABSTRACT Three phases are typically observed during solar flares: the preflare, impulsive, and decay phases. During the impulsive phase, it is believed that the electrons and other particles are accelerated after the stored energy in the magnetic field is released by reconnection.

No Evidence Supporting Flare Driven High-Frequency Global Oscillations

, 2012
The underlying physics that generates the excitations in the global low-frequency, < 5.3 mHz, solar acoustic power spectrum is a well known process that is attributed to solar convection; However, a definitive explanation as to what causes excitations in

Industrial Development, Poverty Reduction, and Inequality: A Robustness Test Using Nighttime Lights in Vietnam

Sustainable Development, EarlyView.
ABSTRACT This paper examines the interplay between sectoral growth compositions, initial inequality, and poverty reduction in Vietnam during the 2000s, utilizing disaggregated provincial‐level data. The analysis focuses on the differential impacts of industrial and agricultural sector growth on poverty alleviation while also assessing the moderating ...

Impact of particulate matter exposure on melanoma risk: A multicentre case–control study

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Long‐term exposure to higher levels of PM10 and PM2.5 may have a protective effect against melanoma, potentially due to the reduction in ultraviolet radiation. Abstract Background The relationship between particulate matter (PM) exposure and melanoma risk remains largely unexplored.

Solar flares: An overview

Advances in Space Research, 1992
This is a survey of solar phenomena and physical models that may be useful for improving forecasts of solar flares and proton storms in interplanetary space. Knowledge of the physical processes that accelerate protons has advanced because of gamma-ray and X-ray observations from the Solar Maximum Mission telescopes.

On the Optimal Prediction of Extreme Events in Heavy‐Tailed Time Series With Applications to Solar Flare Forecasting

Journal of Time Series Analysis, EarlyView.
ABSTRACT The prediction of extreme events in time series is a fundamental problem arising in many financial, scientific, engineering, and other applications. We begin by establishing a general Neyman–Pearson‐type characterization of optimal extreme event predictors in terms of density ratios.

Electron acceleration in solar flares [PDF]

Solar Physics, 1989
AbstractFor the period September 1978 to December 1982 we have identified 55 solar flare particle events for which our instruments on board the ISEE-3 (ICE) spacecraft detected electrons above 10 MeV. Combining our data with those from the ULEWAT spectrometer (MPI Garching and University of Maryland) electron spectra in the range from 0.1 to 100 MeV ...

Fractal Reconnection in Solar and Stellar Environments

, 2016
Recent space based observations of the Sun revealed that magnetic reconnection is ubiquitous in the solar atmosphere, ranging from small scale reconnection (observed as nanoflares) to large scale one (observed as long duration flares or giant arcades ...

A primitive asteroid that lived fast and died young sampled by a xenolith in the Cold Bokkeveld CM2 carbonaceous chondrite

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 464-483, March 2025.
Abstract Xenoliths in carbonaceous chondrites include lithologies that are unrepresented in the meteorite record and so are a rich source of information on asteroid diversity. Cold Bokkeveld is a CM2 regolith breccia that contains both hydrous and anhydrous lithic clasts. Here, we describe a hydrous clast with a fine‐grained rim.
