XRISM reveals a variable, multi-phase outflow-inflow structure during the X-ray obscured 2024 outburst of the black hole transient V4641 Sgr

Maxime Parra, Megumi Shidatsu, Ryota Tomaru +23

We report the results of a simultaneous X-ray and optical spectroscopy campaign on the Galactic black hole X-ray binary V4641 Sgr, carried out with XRISM and the Seimei telescope d…

Stellar $β^{-}$ -decay rate of $^{63}$ Ni and its impact on the $s$ -process nucleosynthesis in massive stars

Xin-Xu Wang, Bao-Hua Sun, Toshitaka Kajino +4

The $β^{-}$ -decay rate of $^{63}$ Ni, an important branching point, affects the subsequent nucleosynthesis in the weak component of the slow-neutron capture process (weak $s$ -proces…
