Using a particle accelerator to understand supernovas


Researchers want to decipher some supernova mysteries through an experiment carried out on the GANIL particle accelerator (acronym for Grand Accélérateur National d’Ions Lourds), located in Caen, a city in France.

The team responsible for the research also hopes to better understand the role of neutrinos (popularly known as “ghost particles”) in the evolution of these explosive stars.

These particles are not affected by magnetic fields and have high volatility. Although they are poorly understood by science, it is already known that they have many similarities with electrons, except for the fact that they are smaller and have no electrical charge.

The role of neutrinos in supernovae

To understand supernovae, which are collapsing stars, you need more information about neutrinos. That’s because the pressure on the star before the explosion causes a combination of protons and electrons, which releases a large amount of protons and neutrinos.

Although science already knows that 99% of the energy emitted by a supernova is in the form of phantom particles, which are responsible for driving the explosion typical of this process, there are still many doubts.

Through the particle accelerator GANIL, scientists intend to discover the exact role of these particles in this process and what really happens inside the star.
