Douglas BoubertCambridge Fluids Network - fluids-related seminars16 May 2018 1:45pmSackler Lecture Theatre, IoAHypervelocity stars are objects travelling fast enough to escape the Milky Way. In this talk I will showcase the menagerie of hypervelocity stars through the lens of Gaia DR2: main-sequence stars and pulsars, white dwarfs and subdwarfs. Alongside the observations, I will present the theories that try to explain their extreme velocity. I will end by highlighting the possibility of using these objects to study supernovae (including Type Ia), massive black holes and the Local Group.
