Understanding the impact of active M dwarf stars on the atmospheric equilibrium and
surface conditions of a habitable zone Earth-like planet is key to assessing M dwarf planet …

Low-mass stars show evidence of vigorous magnetic activity in the form of large flares and
coronal mass ejections. Such space weather events may have important ramifications for the …

Solar energetic particle (SEP) events are related to both solar flares and coronal mass
ejections (CMEs) and they present energy spectra that span from a few keV up to several …

Stellar flares present challenges to the potential habitability of terrestrial planets orbiting M
dwarf stars through inducing changes in the atmospheric composition and irradiating the …

Ground level events (GLEs) occupy the high-energy end of gradual solar energetic particle
(SEP) events. They are associated with coronal mass ejections (CMEs) and solar flares, but …

Proxima b is a terrestrial-mass planet in the habitable zone of Proxima Centauri. Proxima
Centauri's high stellar activity, however, casts doubt on the habitability of Proxima b …

It turned out to be really a rare and happy occasion to know exactly when and how a new
branch of space physics was born, namely, a physics of solar cosmic rays. It happened on …

Despite the significant progress achieved in recent years, the physical mechanisms
underlying the origin of solar energetic particles (SEPs) are still a matter of debate. The …

Discovery of frequent superflares on active cool stars opened a new avenue in
understanding the properties of eruptive events and their impact on exoplanetary …

A statistical analysis of the relationship between solar energetic particles (SEPs) and
properties of solar flares and coronal mass ejections (CMEs) is presented. SEP events …
