    Invited Presentation

    Accreting neutron stars show a broad range of nuclear physics driven observable phenomena. These include short and long X-ray bursts, superbusrts, possible hyper bursts, absorption features in spectra, and crustal cooling. I will review the open questions as well as the current status and prospects of understanding the underlying nuclear physics. In that context I will present some recent...

    Since the discovery of the kilonova GRB130603B (Tanvir et al. 2013) and the gravitational-wave event GW170817 (Villar et al. 2017), neutron-star mergers (NSMs) have been regarded as the leading candidates for the r-process nucleosynthesis site. Although MeV gamma rays from unstable r-process nuclei would provide direct evidence of the r-process site, their expected luminosities are very dim...

    Type I X-ray bursts, one of the explosive astrophysical phenomena, provide important sites for nucleosynthesis. The 14O(ฮฑ,p)17F reaction is a key breakout pathway from the hot CNO cycle and strongly influences the onset of the rapid proton-capture process. However, most available constraints rely on indirect measurements, and direct cross-section data in the low-energy regime relevant to X-ray...

    Type I bursts are transient explosions triggered by the thermonuclear burning of the accreted matter accumulated on neutron star (NS) surfaces. Among Type I bursters, several sources exhibit bursts with nearly constant recurrence times ($t_{\rm rec}$), known as โ€œclocked burstsโ€. Clocked bursters serve as useful probes for the nature of low-mass X-ray binaries (LMXBs)โ€”including accretion rate,...

    Recent experimental data have demonstrated that the coupled-channels
    approach significantly overestimates fusion cross sections at deep subbarrier
    energies. This phenomenon, referred to as fusion hindrance,
    was first identified in the 60Ni+89Y system, and has subsequently been observed
    in several other medium-heavy systems, such as 64Ni+64Ni. However, it remains
    unclear to what...

    Lithium is the heaviest element produced during Big Bang nucleosynthesis. The amount produced can be predicted through the cosmic microwave background and measured through old metal-poor stars. Li has two stable isotopes, with Li-7 being more abundant than Li-6.

    Abstract: The neutron-capture rate in the rapid neutron-capture process (r-process) is one of the major sources of uncertainty, leaving the physical conditions for the r-process not fully constrained [1]. It was suggested that the compound-nucleus neutron-capture rate of 130Sn has a large impact on final r-process elemental abundances [1, 2]. We performed a (d,p) surrogate-reaction measurement...
