An introduction to pulsars: objects that have more mass than the sun but are only around 20km in diameter, possessing an extremely high rotational stability and a very strong magnetic field. Aris Karastergiou (Physics Lecturer and Senior Research Fellow at St Edmund Hall, University of Oxford) describes them as “nature’s ticking clocks” and explains how the changing rate of ‘ticks’ can inform you about the movement of the ‘clocks’.
This is one in a series of short 'Teddy Talks' presented at St Edmund Hall's Research Expo in 2017.
