Type I X-ray bursts are thermonuclear explosions on the surface of accreting neutron stars in low mass X-ray binaries. Hydrogen-rich X-ray bursts burn protons far from the line of stability, resulting in very energetic ($\sim10^{38}$ erg) events and can release energy in the form of neutrinos from $\beta$-decays. Some recent literature suggested that this energy loss due to neutrinos could be...
The presence of live (undecayed) $^{60}$Fe in geological records indicates a young supernova remnant engulfed our solar system 2-3 million years ago. While no terrestrial processes generate $^{60}$Fe, cosmic rays make this radioisotope on rocky solar system bodies such as asteroids via the spallation of nickel on the body’s surface. By using a physical model to analyze $^{60}$Fe production as...
Presolar grains are microscopic crystals found inside primitive meteorites, whose isotopic compositions suggest that, unlike the surrounding rock, they were formed before the early solar system. Classical novae have been proposed as the site of origin for particularly $^{30}$Si-enriched grains [1]. However, large uncertainties in the $^{30}$P(p,$\gamma$)$^{31}$S reaction rate make modeling the...
The recent measurement of gravitational wave from neutron star merger event, GW170817, made a lot of people fascinated. Especially, nuclear- and astro-physicists are very excited on the information the event brought us. The merger provided a wide constraint via tidal deformability parameter on the equation of state of nuclear matter but it does not give us information about the symmetry...
