  1. 156. Explosive nucleosynthesis of massive stars
    Marco Limongi (INAF - Observatory of Rome)

    Invited
  2. 18. The intermediate neutron capture process in AGB stars
    Arthur CHOPLIN (Université Libre de Bruxelles)

    Oral

    Despite considerable progresses over the past few decades, the origin of trans-iron elements is not yet fully understood. In addition to the slow (s) and rapid (r) neutron capture processes, an intermediate neutron capture process (i-process) is thought to exist at neutron densities intermediate between the s- and r-processes. The existence of this process is supported by the observation of...

  3. 8. Presolar Grain Isotopic Ratios as Constraints to Nuclear and Stellar Parameters of Asymptotic Giant Branch Star Nucleosynthesis

    Oral

    Recent models for evolved low-mass stars (with M <=3 Mo), undergoing the asymptotic giant branch (AGB) phase assume that magnetic flux-tube buoyancy drives the formation of 13C reservoirs in He-rich layers. We illustrate their crucial properties, showing how the low abundance of 13C generated below the convective envelope hampers the formation of primary 14N and the ensuing synthesis of...

  4. 126. Origin of Short-lived Radio nuclides in the Early Solar System
    Dr Tejpreet Kaur (Panjab University, India)
    06/09/2022, 12:00
    Oral

    The short-lived radionuclides (SLRs) have a half-life ≤ 100 Myr. The excess abundance of their daughter nuclides in various meteoritic phases confirms the existence of SLRs in the early solar system (ESS). In this work, we have developed Galactic chemical evolution (GCE) models to understand the stellar sources of SLRs, $^{26}$Al, $^{36}$Cl, $^{41}$Ca, $^{53}$Mn, and $^{60}$Fe in the ESS. ...

  5. 136. Sensitivity of X-ray burst models to nuclear reaction rates for a range of low-mass X-ray binaries
    Alfredo Estrade (Central Michigan University)
    06/09/2022, 12:15
    Oral

    Accreting neutron stars offer unique opportunities to study the properties of matter in extreme density environments and nuclear processes involving very unstable isotopes. X-ray burst are one of the rich observables that can be used to test models of accreting neutron stars. The burst are driven by thermonuclear reactions near the surface of the neutron star that proceed through (a,p) and...
