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 … Continue reading "CRA Cosmic Coffee: Ziqian Hong"
3D Radiation Magneto-hydrodynamic Simulations of Accretion Disks around Supermassive Black Holes Abstract: Black hole accretion disks convert the gravitational energy of accreted gas to photons and produce varies observational phenomena of AGNs. First principle calculations of black hole accretion disks for a wide range of accretion rates are not only important for understanding various observational … Continue reading "CRA seminar: Dr. Yan-Fei Jiang (University of California Santa Barbara)"
