Galactic archaeology: mining stellar fossils in the Milky Way
The October IOP South Central Branch and University of Surrey talk brings Dr. Payel Das, UKRI Future Leaders Fellow in the Astrophysics research group at the University of Surrey to talk about galactic archaeology...
Stars in the night sky like our Sun have been around almost since the birth of the Universe. They have witnessed a number of interactions between our Milky Way galaxy and other nearby galaxies. What they are made out of and how they move encodes their origins and any interactions they have been involved in. Some stars for example, were born in a nearby galaxy that fell into our Milky Way. Stars are therefore a bit like the fossils we find here on Earth. Galactic archaeologists are collecting many millions of stellar fossils to work out why our Milky Way looks like it does now. I will share some of the secrets of making an excellent galactic archaeologist and will invite you to help me find the origins of some stars in our night sky. You will have the opportunity to understand how astronomers use stars to understand the transformation of galaxies from irregular blobs in the early Universe into the beautiful spiral and elliptical galaxies of today.
