La estrella, que experimenta este tipo de explosiones cada cincuenta años, perdió en el último estallido una masa equivalente al 10% de la masa del Sol

The linear polarization produced by scattering processes in the spectral lines of the IR triplet of Ca II can be observed near the edge of the solar disk. The cause of this polarization was considered a true enigma until the year 2003, in which IAC researchers could carry out sophisticated calculations based on the quantum theory of the spectral line polarization. In this way, they could demonstrate that the physical origin of the enigmatic polarization is the presence of "atomic polarization" in the lower levels of such spectral lines, which produces dichroism (i.e., selective absorption of

Galactic superwinds present a filament-like structure, with strong X ray emissions, which could not be explained until now. Using hydrodynamic calculations, it has been possible to determine that this structure is caused by the autocollimation of the material that forms the galactic superwinds. The autocollimation is caused by the interaction of material escaping from stellar superclouds, compact groups of stars revealed by the HST in which intense stellar formation has given rise to at least 100 very massive and very luminous stars. This interaction also explains the X ray emission.
