Radio Waves from Massive Stars
Holly Andrews (University College London)
A star’s life is defined by how much mass it has. We can consider the various stages of a stars life, from the birth of stars in stellar nurseries to the death of the star. Massive stars are at least 8 times as large as our Sun, and will end their lives in an explosive supernovae, with the most massive stars becoming a black hole. Join PhD Researcher Holly Andrews as they show how we can use radio waves emitted by the winds of these massive stars in order to see how much material is lost by the stars, and how this can impact both the star and its surrounding environment.

Our Explosive Sun
Ryan French (Mullard Space Science Laboratory, University College London)
Our Sun is a highly active and dynamic place. With a surface temperature of over 5000°C, it is constantly churning and throwing material off into deep space, guided by its powerful magnetic field. Flares, prominences and even vast coronal mass ejections are common place and lead to a kind of space weather affecting the wider solar system. PhD Researcher Ryan French takes us on a journey to our very own star to understand its complex and often violent nature, and how it can affect us here on Earth!
