ESOcast 76: A Polarised View of Stellar Magnetism
25 września 2015
ESO telescopes are being used to search for the subtle signs of magnetic fields in other stars and even to map out the star spots on their surfaces.
This ESOcast looks at how this information — and particularly the polarisation of light — is beginning to reveal how and why so many stars, including our own Sun, are magnetic, and what the implications might be for life on Earth and elsewhere in the Universe.
You can subscribe to the ESOcasts in iTunes, receive future episodes on YouTube or follow us on Vimeo. Many other ESOcast episodes are also available.
Find out how to view and contribute subtitles to the ESOcast in multiple languages.
