Anna Frebel (born 1980 inBerlin) is a Germanastronomer and author working on discovering the oldest stars in the universe.
Anna Frebel grew up inGöttingen, Germany.[1] After finishing high school, she began studying physics inFreiburg 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 theAustralian National University'sMount Stromlo Observatory in Canberra. Shortly thereafter, a W. J. McDonald Postdoctoral Fellowship brought her to theUniversity of Texas at Austin in 2006, where she continued her studies.[2]
From 2009 to 2011, she was a Clay PostdoctoralFellow at theHarvard–Smithsonian Center for Astrophysics in Cambridge (MA).
In 2012 she moved toMassachusetts Institute of Technology, achieving promotion to full professor in 2022.[3]
In 2005, Frebel discovered the starHE 1327-2326, which is the most iron-deficient star, stemming from a time very shortly after theBig Bang. In 2007 she also discovered the red giant starHE 1523-0901, which is about 13.2 billion years old.
