Isotopic Compositions of Ruthenium Predicted from the NuGrid Project
Seonho Kim, Kwang Hyun Sung, Kyujin Kwak
The isotopic compositions of ruthenium (Ru) are measured from presolar silicon carbide (SiC) grains. In a popular scenario, the presolar SiC grains formed in the outskirt of an asy…

Measuring Masses and Radii of Neutron Stars in Low-Mass X-ray Binaries: Effects of Atmospheric Composition and Touchdown Radius
Myungkuk Kim, Young-Min Kim, Kwang Hyun Sung +2
Methods. We use both a Monte Carlo (MC) sampling and a Bayesian analysis to find the effects of the photospheric composition and the touchdown radius. We apply these two methods to…
