The detection of global weather phenomena in extrasolar hot Jupiters
has provided tremendous insights into their atmospheric structure. Non-irradiated substellar atmospheres probe weather in an entirely different regime, where global atmospheric flows result primarily from a combination of rapid rotation and internal convection - e.g., as in the atmosphere of Jupiter - rather than from external forcing. Isolated brown dwarfs are ideal targets for such investigations because they possess planet-like atmospheric dynamics, yet have greater intrinsic brightness and lack nearby bright stars to contaminate observations. I will review the study of clouds and weather phenomena in brown dwarf atmospheres, and will present evidence that features analogous to Jupiter's Great Red Spot are ubiquitous on cool substellar atmospheres. I will also discuss the occurrence of asteroid belt-like debris disks around solar neighbourhood stars. These nearest warm debris disks offer exciting prospects for direct imaging of exosolar frost-line regions with the current generation of extreme-contrast imaging telescopes.
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
