Dust and Planet Formation

How do planets form? What happens to a planetary system when its central star dies? These two questions drive the bulk of my research in Astronomy. I think answering these questions will tell us important things about how many habitable planets reside in our Milky Way and the ultimate fate of the Solar System.

  • This Website Featured in Optics & Photonics News 5.01.2012 This website was cited in the article "What Makes a Good Website for Scientists?" by Marc Kuchner in Optics & Photonics News. In it, Marc discusses what elements make for a good research website. This website is noted for being "generous and collaborative" by offering tools and slides from talks--click on the Tools Link to see if there's anything useful--don't forget to email me if there's something in particular you'd like to see!
  • Debes & Sigurdsson, 2002 reaches 100 citations 2.20.2012 One of my first papers as a graduate student and the subject of my second year project, "Are There Unstable Planetary Systems around White Dwarfs?", has just broken the 100 citation count. My overall H index is 11. Thanks to all the researchers who have read my work and used it as a foundation to discover new things!
  • Dead Stars and Doomed Planets article in Astronomy Magazine 2.13.2012 Pick up a copy of the March 2012 issue of Astronomy Magazine to find an article me and Marc Kuchner wrote on the fate of planetary systems during post-main sequence evolution.
  • Invited talk at the Planets around Stellar Remnants Conference 1.23.2012 I am giving an invited talk at the Planets around Stellar Remnants conference, entitled: "Performing autopsies of planetary systems with the WIRED survey and new dynamical models".
  • New Paper! 1.3.2012 The Link Between Planetary Systems, Dusty White Dwarfs and Metal Polluted White Dwarfs , accepted to ApJ. This paper poses the question: "If the Sun turned into a white dwarf, would we see evidence of our planetary system?" The short answer is yes! This paper also follows the tidal disruption of a rubble pile asteroid around a white dwarf and makes a prediction that stars may have up to 800x the mass in their asteroid belts compared to the Solar System.
