Solar–Stellar Connection: X-Ray Flares to Energetic (E > 10 MeV) Particle Events

The Astrophysical Journal, 2023
Energetic particle environments are an important factor for the viability of life on exoplanets surrounding flare stars. In the heliosphere, large gradual solar energetic ( E > 10 MeV) particle (SEP) events are produced by shocks from fast coronal mass ...

Solar Coronal Mass Ejections Plasma Diagnostics Expressed as Potential Stellar CME Signatures

The Astronomical Journal, 2022
Abstract Solar coronal mass ejections (CMEs) have a strong association with solar flares that is not fully understood. This characteristic of our Sun’s magnetic activity may also occur on other stars, but the lack of successfully detected stellar CMEs makes it difficult to perform statistical studies that might show a similar association

Stellar magnetic activity – Star-Planet Interactions

EPJ Web of Conferences, 2015
Stellar magnetic activity is an important factor in the formation and evolution of exoplanets. Magnetic phenomena like stellar flares, coronal mass ejections, and high-energy emission affect the exoplanetary atmosphere and its mass loss over time.

Solar evolution and extrema: current state of understanding of long-term solar variability and its planetary impacts

Progress in Earth and Planetary Science, 2021
The activity of stars such as the Sun varies over timescales ranging from the very short to the very long—stellar and planetary evolutionary timescales.

Power-law Distribution of Solar Cycle–modulated Coronal Jets

The Astrophysical Journal Supplement Series, 2023
Power-law distributions have been studied as a significant characteristic of nonlinear dissipative systems. Since discovering the power-law distribution of solar flares that was later extended to nanoflares and stellar flares, it has been widely accepted

Looking for the elusive stellar coronal mass ejections. How can LOFAR help?

, 2022
Abstract: Coronal mass ejections (CMEs) are the most explosive manifestations of stellar magnetic activity. In the solar case, CMEs and flares are associated with each other and this association increases with increasing flaring energy, reaching 100% for high energies. But does this hold true for other stars?

Warfare, Labor, and Urban Stress: Divergent Health Trajectories in Mongol‐Period Karakorum

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study examines major palaeopathological trends in Mongol‐period Karakorum and incorporates them into the existing body of research in order to deepen our understanding of health and survival, the impacts of conflict and violence on past populations, and the lived experiences of the city's diverse inhabitants within the broader socio ...

Terendak Military Cemetery: Bodies, Burials, and ‘Operation Bring Them Home'

Australian Journal of Politics &History, EarlyView.
Terendak Military Cemetery occupies an unusual position in the history of Australian war cemeteries. Initially established to service the needs of the community at Terendak Garrison—the operational base for Commonwealth forces in Malaya during the early years of the Cold War—it became the official overseas burial site of Australian dead during the ...

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

Meteoritics &Planetary Science, EarlyView.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...
