Impacts of Energetic Particles from T Tauri Flares on Inner Protoplanetary Discs
Valentin Brunn, Christian Rab, Alexandre Marcowith +3
T Tauri stars are known to be magnetically active stars subject to strong flares observed in X-rays. These flares are likely due to intense magnetic reconnection events during whic…

Energetic particles accelerated via turbulent magnetic reconnection in protoplanetary discs -- I. Ionisation rates
Valentin Brunn, Fulvia Pucci, Alexandre Marcowith +3
Context. Ionisation controls the chemistry, thermal balance, and magnetic coupling in protoplanetary discs. However, standard ionisation vectors such as stellar UV, X-rays, Galacti…

Effects of energetic particles produced by magnetic reconnection on discs of young stars
Valentin Brunn
T Tauri stars and their discs are crucial for understanding stellar evolution and the formation of planets in low-mass systems. These stars exhibit significant variability, notably…
