Bars are ellipsoidal-like structures that appears in the inner regions of a large fraction of discs of galaxies. Bars universal features present at all galactic masses, morphological types and across the Hubble time. Stars forming bars follow elongated orbits aligned with the bar major-axis. These barred structures rotate as a coherent structure

During the early stages of planetary formation, planets undergo strong changes in their physical and orbital properties due to internal and external forces, which also affect their primordial atmospheres composed mainly of H and He. The study of planets in these early stages and their comparison with the more mature planet population is crucial for

Star formation is a vital phenomenon across all fields of astronomy, shaping our universe in all its vastness, from the small scale of exoplanets to the large scales of galaxies and beyond. There are nevertheless still many unknowns surrounding star formation because of its complexity. Spiral arms are important sites of star formation, yet in spite
