The Role of Rotation on the Yields of the Two γ-Ray Emitters 26Al and 60Fe Ejected by Massive Stars
The Astrophysical JournalWe show that the observed ^60 Fe/ ^26 Al flux ratio provided by the SPectrometer on INTEGRAL satellite (0.24 ± 0.04) can be reproduced only if rotation is taken into account in the computation of the stellar models.

Scissors strength in the quasi-continuum of actinides
EPJ Web of Conferences, 2014 The M1-scissors resonance has been measured for the first time in the quasi-continuum of actinides. The strength and position of the resonances in 231,232,233Th were determined by particle-γ coincidences using deuteron induced reactions on a 232Th target.

, 2001 Many radioactive nuclei relevant for gamma-ray astrophysics are synthesized during explosive events, such as classical novae and supernovae. A review of recent results of explosive nucleosynthesis in these scenarios is presented, with a special emphasis on the ensuing gamma-ray emission from individual nova and supernova explosions.

Nucleosynthesis in explosive environments : neutron star mergers and core-collapse supernovae [PDF]
, 2016 Several nucleosynthesis processes are responsible for the production of the chemical elements in the universe. Explosive ejecta in core-collapse supernovae typically produce intermediate-mass elements up to the iron-group nuclei, although the exact ...

Role of clusters in nuclear astrophysics with Cluster Nucleosynthesis Diagram (CND)
, 2013 The role of nuclear clustering in stellar reactions is discussed, with Cluster Nucleosynthesis Diagram (CND) proposed before, for nucleosynthesis in stellar evolution and explosive stellar phenomena.

Explosive nucleosynthesis with fast neutrino-flavor conversion in core-collapse supernovae
, 2022 Fast neutrino-flavor conversion (FFC) is a possible game-changing ingredient in core-collapse supernova (CCSN) theory. In this paper, we examine the impact of FFC on explosive nucleosynthesis by including the effects of FFC in conjunction with asymmetric

Low-mass neutron star nucleosynthesis -- stripping scenario [PDF]
This paper examines nucleosynthesis in a low-mass neutron star crust that loses mass due to accretion in a close binary system and, reaching a hydrodynamically unstable configuration explodes.

Nuclear Aspects Of Stellar And Explosive Nucleosynthesis
, 2007 The majority of nuclear reactions in astrophysics involve unstable nuclei which are not fully accessible by experiments yet. Therefore, there is high demand for reliable predictions of cross sections and reaction rates by theoretical means.
