Henrietta S. Leavitt & Cepheid Variable Stars

by Peter Eyland

This is a talk that Peter has given to the Amateur Astronomy group recently in October 2019.

Please note - Peter had many animations in his talk. Some are repeated below eg Cepheid Variables changing in a galaxy over time. eg how stars pulsate & why the opacity of stars change due to pressure, ionisation etc. Some appear as static images (i.e. not moving).
