3D simulation of magnetic islands dynamics during solar flare events

The whims of a star

Yet, the start of a new solar cycle in 2008 marked the beginning of a three-year period of intense activity, which is of major interest to Dr. Janvier. Indeed, with heightened solar activity, the number of unpredictable magnetic disruptions is bound to increase, and this is where her work on 3D simulation steps in.
First, Dr. Janvier is investigating and performing 3D modeling of the dynamics involved in magnetic reconnection—the crucial point where magnetic field lines come so close to each other that they connect and release a massive burst of energy. This “reconnection” phenomenon is the focus of her work and, in the long run, the key to a better understanding of space physics as well as plasmas involved in the generation of nuclear fusion power. Secondly, this highly transient “reconnection” episode is believed to be one of the most efficient ways to convert stored-up magnetic energy into heating and thermal energy.
Considering that her achievements cover both fusion science and astrophysics, Dr. Janvier’s work may not only lead to better predictions of space weather and a better understanding of nuclear fusion, but it also may result in better prevention of the consequences of geomagnetic storms on human lives and infrastructures.
