German astronomer
Anna Frebel (born 1980 in Berlin) is a German astronomer and author working on discovering the oldest stars in the universe.
Career.
Anna Frebel grew up in Göttingen, Germany. After finishing high school, she began studying physics in Freiburg im Breisgau but did not finish the physics program and did not obtain a physics degree there. Instead she enrolled in an astronomy program in Australia, where she obtained a PhD in Astronomy from the Australian National University's Mount Stromlo Observatory in Canberra. Shortly thereafter, a W. J. McDonald Postdoctoral Fellowship brought her to the University of Texas at Austin in 2006, where she continued her studies.
From 2009 to 2011, she was a Clay Postdoctoral Fellow at the Harvard–Smithsonian Center for Astrophysics in Cambridge (MA).
In 2012 she moved to Massachusetts Institute of Technology, achieving promotion to full professor in 2022.
Discoveries.
In 2005, Frebel discovered the star HE 1327-2326, which is the most iron-deficient star, stemming from a time very shortly after the Big Bang. In 2007 she also discovered the red giant star HE 1523-0901, which is about 13.2 billion years old.
