Kilonova Emission From Black Hole-Neutron Star Mergers. I. Viewing-Angle-Dependent Lightcurves

16 May 2020 Zhu Jin-Ping Yang Yuan-Pei Liu Liang-Duan Huang Yan Zhang Bing Li Zhuo Yu Yun-Wei Gao He

In this paper, we present a numerical method to study the predicted lightcurves as a function of viewing angle. We extrapolate the fitting formulae for the mass and velocity of tidal dynamical ejecta across a wide range of mass ratio validated with 66 simulations and use them in the calculations of the kilonova lightcurves...
