Astronomers have presented the initial results of the Large Impact of Magnetic Fields on the Evolution of Hot Stars (LIFE) project. Among determining fundamental parameters of 15 stars, they found that two of them have magnetic fields. LIFE’s main goal is to search for magnetic fields in hot post-main sequence stars. The project also aims to evaluate the model of magnetic flux conservation and to investigate the impact of magnetic fields on stellar evolution, and vice versa. In order to achieve its scientific goals, LIFE utilizes the Echelle SpectroPolarimetric Device for the Observation of Stars (ESPaDOnS) at the Canada France Hawaii Telescope (CFHT) in Hawaii.
During the observations, the team wa...
