Solar energetic particles, or SEPs, from suprathermal (few keV) up to relativistic (∼∼ few
GeV) energies are accelerated near the Sun in at least two ways:(1) by magnetic …

Shortly after the seminal paper “Self-Organized Criticality: An explanation of 1/f noise” by
Bak et al.(1987), the idea has been applied to solar physics, in “Avalanches and the …

Recent work has demonstrated that high levels of X-ray and UV activity on young M dwarfs
may drive rapid atmospheric escape on temperate, terrestrial planets orbiting within the …

Coherent radio bursts detected from M dwarfs have some analogy with solar radio bursts but
reach orders of magnitude higher luminosities. These events trace particle acceleration …

Characterizing the UV spectral energy distribution (SED) of an exoplanet host star is
critically important for assessing its planet's potential habitability, particularly for M dwarfs, as …

Forbush decrease (or, in a broader sense, Forbush effect)-is a storm in cosmic rays, which is
a part of heliospheric storm and very often observed simultaneously with a geomagnetic …

We survey the statistical properties of 1191 solar electron events observed by the WIND 3DP
instrument from< 1 keV to≳ 300 keV for a solar cycle (1995 through 2005). After taking into …

Abstract The Committee on Space Research (COSPAR) is updating its Roadmap on Space
Weather. As input for this update, the COSPAR International Space Weather Action Teams …

Context. Solar energetic particles (SEPs) are an important space radiation source,
especially for the space weather environment in the inner heliosphere. The energy spectrum …

This chapter provides an overview on solar energetic particles (SEPs) and their association
to space weather, both from the scientific as well as from the applications perspective. A …
