    Jonathan E. Grindlay

    Robert Treat Paine Professor of Practical Astronomy

    Research Interests: High Energy Astrophysics: Studies of accretion onto compact objects (black holes, neutron stars and white dwarfs). Development of detectors and telescopes for wide-field imaging surveys of black holes discovered in soft-to-hard  X-rays. Time Domain Astrophysics: X-ray/optical/IR studies of Transients and variability of black holes in binaries and galactic nuclei to probe extreme physics phenomena and constrain black hole populations. Days-to-Century optical variability studies of stars and quasars with DASCH and followup spectroscopy to constrain formation and evolution of black holes.... Read more about Jonathan E. Grindlay

    Speaker: Brenda Matthews (Herzberg Institute)

    Title: Results from the Herschel DEBRIS Survey

    Abstract: Debris disks are second-generation dusty disks observed around main sequence stars. They are generated by ongoing collisions between larger planetesimal bodies in the disk and indicate that the system succeeded in building large solids within the long-dispersed protoplanetary disk. Debris disks were originally detected by IRAS through their thermal emission and have also...
