The Variable Sun

  • Antony Cooke
Part of the Astronomers' Universe book series (ASTRONOM)


The Sun is central to everything in our existence; it is also central to our potential demise, for many reasons. It is a relatively stable main sequence star, but proxy records from antiquity indicate that its output has varied often over past millennia (Fig. 4.1).
