Additional acceleration of solar-wind particles in current sheets of the heliosphere [PDF]
, 2015 Particles of fast solar wind in the vicinity of the heliospheric current sheet (HCS) or in a front of interplanetary coronal mass ejections (ICMEs) often reveal very peculiar energy or velocity profiles, density distributions with double or triple peaks,

SCATTERING POLARIZATION IN SOLAR FLARES [PDF]
The Astrophysical Journal, 2013 There is an ongoing debate about the origin and even the very existence of a high degree of linear polarization of some chromospheric spectral lines observed in solar flares. The standard explanation of these measurements is in terms of the impact polarization caused by non-thermal proton and/or electron beams.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The impulsivity of solar flares: concepts and applications [PDF]
, 2018 During the impulsive phase of solar flares a distribution of nonthermal electrons propagates from the site of energy release towards the lower layers of the solar atmosphere.

Solar Magnetic Activity and Its Terrestrial Impact through Correlations with Drought Indices
Physical Sciences and TechnologySolar activity manifests itself in the form of sunspots on the solar surface and solar flares, which can influence Earth's climatic conditions, including drought in mid-latitude regions.

Econometrics at the Extreme: From Quantile Regression to QFAVAR1
Journal of Economic Surveys, Volume 40, Issue 3, Page 1672-1686, July 2026.ABSTRACT This paper surveys quantile modelling from its theoretical origins to current advances. We organize the literature and present core econometric formulations and estimation methods for: (i) cross‐sectional quantile regression; (ii) quantile time series models and their time series properties; (iii) quantile vector autoregressions for ...

Distribution of low-power solar flares by brightness rise time
Solar-Terrestrial Physics, 2018 Using data from the international flare patrol for 1972–2010, we have formed an electronic database for more than 123 thousand solar flares. We determined the mean brightness rise time (flash phase) for flare area classes and importance. We show that the

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped proton population during the storm.

THE SOLAR FLARE IRON ABUNDANCE [PDF]
The Astrophysical Journal, 2012 The abundance of iron is measured from emission line complexes at 6.65 keV (Fe line) and 8 keV (Fe/Ni line) in {\em RHESSI} X-ray spectra during solar flares. Spectra during long-duration flares with steady declines were selected, with an isothermal assumption and improved data analysis methods over previous work.

Annalen der Physik, Volume 538, Issue 6, June 2026.This study examines slowly rotating traversable wormholes supported by string fluids whose properties change with radius. The matter smoothly shifts from a de Sitter‐like core to a string‐dominated exterior, producing a regular, horizon‐free spacetime.
