Stellar and High-Energy Astrophysics at UBC
Our group’s research interests range over the following areas:
We have completed a comprehensive study of massive white dwarfs with Gaia EDR3 . We can account for the numbers of white dwarfs between 0.95 and 1.15 solar masses with white dwarf cooling models and the rate of star formation in the Galaxy over the past few billion years. In fact, these massive white dwarfs …

We developed a novel method to reconstruct and determine the ages of all the young clusters within 200 pc of the Sun using Gaia EDR3 including the Pleiades and four other clusters . In the process we found two white dwarfs lost from the Pleiades bringing the total number of Pleiad WDs to three and …
Alumna Ilaria Caiazzo led a team based at Caltech and elsewhere to discover the smallest and therefore most massive white dwarf ever found. It is within about one percent of the maximum mass that a white dwarf can be, the Chandrasekhar mass. It rotates every seven minutes and harbours a magnetic field more than a …
How is our understanding of astrophysical phenomena connected with our understanding of fundamental physics?
