Pier-Emmanuel Tremblay

I am Associate Professor in the Astronomy and Astrophysics group and ERC Starting Grant fellow. From 2013 to 2015 I was a Hubble Fellow at Space Telescope Science Institute in Baltimore, and from 2011 to 2013 I was an Alexander von Humboldt Fellow at the Zentrum für Astronomie Heidelberg. I obtained my PhD at Université de Montréal (2011). I am interested in white dwarfs and stars as physics laboratories and probes of Galactic history. I develop model atmospheres and 3D radiation-hydrodynamical simulations. Recently we have discovered the first direct evidence of solid white dwarfs (Nature, 9 January 2019), a massive star with a bizarre atmosphere could be two white dwarfs that merged together (Nature Astronomy, 2nd March 2020) and the source of carbon in the Universe (Nature Astronomy, 7 July 2020).
