Planets in close proximity to their parent star, such as those in the habitable zones around M dwarfs, could be subject to particularly high doses of particle radiation. We have carried out test-particle simulations of ~GeV protons to investigate the propagation of energetic particles accelerated by flares or travelling shock waves within the stellar wind and magnetic field of a TRAPPIST-1-like system. Turbulence was simulated with small-scale magnetostatic perturbations with an isotropic power… 
Stellar Winds Drive Strong Variations in Exoplanet Evaporative Outflow Patterns and Transit Absorption Signatures
Stellar wind and photon radiation interactions with a planet can cause atmospheric depletion, which may have a potentially catastrophic impact on a planet’s habitability. While photon interactions
The cosmic ray-driven streaming instability in astrophysical and space plasmas
Energetic non-thermal particles, or cosmic rays, are a major component of astrophysical plasmas next to magnetic fields, radiation, and thermal gas. Cosmic rays are usually sub-dominant in density
The Earth-like Galactic cosmic ray intensity in the habitable zone of the M dwarf GJ 436
Galactic cosmic rays are energetic particles important in the context of life. Many works have investigated the propagation of Galactic cosmic rays through the Sun’s heliosphere. However, the cosmic

The discovery of terrestrial exoplanets orbiting in habitable zones around nearby stars has been one of the significant developments in modern astronomy. More than a dozen such planets, like
Stellar versus Galactic: the intensity of cosmic rays at the evolving Earth and young exoplanets around Sun-like stars
Energetic particles, such as stellar cosmic rays, produced at a heightened rate by active stars (like the young Sun) may have been important for the origin of life on Earth and other exoplanets. Here
Giant white-light flares on fully convective stars occur at high latitudes
White-light flares are magnetically driven localized brightenings on the surfaces of stars. Their temporal, spectral, and statistical properties present a treasury of physical information about
A Review of Possible Planetary Atmospheres in the TRAPPIST-1 System
TLDR
It is shown that (i) Hubble Space Telescope transit observations, (ii) bulk density measurements comparison with H2-rich planets mass-radius relationships, (iii) atmospheric escape modelling, and (iv) gas accretion modelling altogether offer solid evidence against the presence of hydrogen-dominated—cloud-free and cloudy—atmospheres around TRAPPIST-1 planets.
Reconstructing Extreme Space Weather from Planet Hosting Stars
The field of exoplanetary science is making rapid progress both in statistical studies of exoplanet properties as well as in individual characterization. As space missions provide an emerging picture
Accounting for multiplicity in calculating eta Earth
Using the updated exoplanet population parameters of our previous study, which includes the planetary radius updates from Gaia DR2 and an inferred multiplicity distribution, we provide a revised η⊕
The TRAPPIST-1 JWST Community Initiative
TLDR
A community initiative aiming to develop a well-defined sequential structure for the study of the TRAPPIST-1 planetary system with JWST and to coordinate on every aspect of its preparation and implementation is presented.

The effect of a strong stellar flare on the atmospheric chemistry of an earth-like planet orbiting an M dwarf.
TLDR
The results indicate that the UV radiation emitted during the flare does not produce a significant change in the ozone column depth of the planet, and flares may not present a direct hazard for life on the surface of an orbiting habitable planet.
