Welcome to Cool Star Lab

Our research focuses on the properties of the lowest mass stars, brown dwarfs, and extrasolar planets. We use observational techniques to infer physical properties, study multiple systems, investigate magnetic activity, and measure population statistics. Our tools include spectroscopy, high-resolution imaging, radio interferometry, and monitoring.
