Most stars behave like enormous dynamos, producing intense magnetic fields within them. These magnetic fields then interact with the plasma that constitutes the star’s interior and atmosphere, in a constant tug of war where the prevailing force dominates the dynamics. In the outer region of stars, from the photosphere to the corona, the pressure exerted by the gas is less
Among the stars known to host more than one planet, V1298 Tau deserves particular attention. This star, located approximately 360 light years away from us, is around 20 million years old and possesses a planetary system with four exoplanets discovered so far. Due to these characteristics, V1298 Tau can offer valuable insights into the planetary formation process and the early
The study of the exoplanets orbiting around young stars (e.g., younger than a few tens of million of years) offer the important opportunity for studying the early evoalutionary phases of those processes that shape the architecture of planetary systems. However, it is quite difficult to detect and study exoplanets around young stars, because of their low number, the complexity of their
The search for young exoplanets is crucial to our understanding of the planetary formation process and the early evolution of planets. The disc of gas and dust from which planets form, in fact, typically disperse in a few million of years. Before that, the young planets interact with all the material orbiting around the star within the disk, triggering important
