Dimitri Veras, PhD

Last updated: 20 September 2014

I am an astrophysicist who researches planets in a wide variety of contexts, across both time and space. I have published academic articles about forming planets, destroying planets, young planets, old planets, planets close to the Solar System, planets far from the Solar System, free-floating planets, and Tatooine-like planets. You can view some media attention regarding my work here from National Geographic, New Scientist (here and here), Universe Today, Astronomy Now, The Daily Mail, USA Today, and AAAS Science.

My current research focus aims to answer some of the biggest mysteries regarding the ultimate fate of extrasolar planets - how they die, and how they can "pollute" very old stars known as "white dwarfs". The Sun will become a white dwarf, and might very well be polluted by asteroids, comets or even planets such as the Earth!

I am currently a Research Fellow in perhaps the largest white dwarf research group in the world, at the University of Warwick. My biography includes postdoctoral research appointments at the University of Cambridge and University of Florida. I obtained my PhD at the University of Colorado at Boulder, and my Bachelor's degree at Yale University.

In addition to research, I have a keen interest in astronomical trivia and associated outreach activities, and am always looking for new applications. I have also been creating geographic astronomy department maps, and welcome your feedback.
