Title: Stellar Physics: from Plasma Dynamics to Stellar Evolution Abstract: New data available from recent space-missions Kepler and GAIA, as well as up-coming missions TESS and PLATO, has introduced a new era for stellar physics. New theoretical/computational models are needed to interpret the wealth of detailed new data. This includes fundamental theories of stellar convection, … Continue reading "CRA Seminar: Dr Jane Pratt"
Title: Dynamical Assembly of Black Hole Binaries in Dense Star Systems Abstract: The discovery of merging black hole (BH) binaries by the LIGO and Virgo experiments has initiated the era of gravitational wave (GW) astrophysics. Detailed comparisons between theoretical and observed waveforms have already tested classical general relativity, and placed stringent constraints on alternative theories … Continue reading "CRA Seminar (Dr. Nicholas Stone, Columbia University)"
Title: Physics of comets after the Rosetta mission Abstract: Most comet questions revolve around whether observed properties are primordial and representative of conditions during the era of planet formation, or whether they are caused by subsequent processing. The Rosetta mission to 67P/Churyumov-Gerasimenko dramatically changed our understanding of comets. It allowed the most detailed study of … Continue reading "CRA Seminar: Dr. Dennis Bodewits (Auburn University)"
Title: CHIME - the Canadian Hydrogen Intensity Mapping Experiment Keith Vanderlinde (University of Toronto) URL: http://dunlap.utoronto.ca/~vanderlinde/ ABSTRACT: Among the great surprises of modern cosmology was the discovery of Dark Energy, which dominates the energy budget of the Universe and is driving the acceleration of its expansion rate. Decyphering its properties and nature will require novel … Continue reading "CRA Seminar (Dr. Keith Vanderlinde, University of Toronto)"

The Degree of Fine-Tuning in our Universe -- and Possibly Others Fred C. Adams, University of Michigan https://lsa.umich.edu/astro/people/jointly-appointed-faculty/fca.html The fundamental constants of nature must fall within a range of values in order for the universe to develop structure and ultimately support life. This talk considers the current constraints on these quantities and assesses the degree … Continue reading "CRA Seminar (Prof. Fred Adams, University of Michigan)"
Could there be an undetected inner planet near the stability limit in Kepler-1647? Abstract: Kepler-1647b is the most recently discovered planet that transits two stars, e.g., a circumbinary planet (CBP). Due to its large orbital separation, Kepler-1647b stands out from the rest of the Kepler CBPs, which mostly reside on much tighter orbits near … Continue reading "CRA Cosmic Coffee: Ziqian Hong"
