The production of about half the heavy elements beyond Fe and Ni is assigned the rapid neutron capture process (r process). The full understanding faces two open questions. (a) The nucleosynthesis path runs close to the neutron-drip line, where presently only limited experimental information is available, and one has to rely on theoretical predictions. (b) While for many years the occurrence of the r process has been associated with supernovae recent studies have cast substantial doubts on this… 
Kilonovae
TLDR
The history and physics of Kilonovae are reviewed, leading to the current paradigm of week-long emission with a spectral peak at near-infrared wavelengths, and the prospects of kilonova detection following future GW detections of NS–NS/BH–NS mergers are assessed.
Kilonovae
TLDR
Joint GW and kilonova observations of GW170817 and future events provide a new avenue to constrain the astrophysical origin of the r-process elements and the equation of state of dense nuclear matter.

Fission and the r -process nucleosynthesis of translead nuclei in neutron star mergers
We study the impact of fission on the production and destruction of translead nuclei during the r-process nucleosynthesis occurring in neutron star mergers. Abundance patterns and rates of nuclear
Hypothesis about Enrichment of Solar System
Despite significant progress in the understanding of galactic nucleosynthesis and its influence on the solar system neighborhood, challenges remain in the understanding of enrichment of the solar
Research program of nuclear astrophysics based on the HIAF
Nuclear astrophysics is an interdisciplinary research field integrating nuclear physics, astrophysics and astronomy. It has always been an important frontier of physics in the world. This paper

Overview: Nearly twenty years ago the influential report “From Quarks to the Cosmos” argued that the growing precision of astrophysical and cosmological measurements would make this field an
INVESTIGATION OF THE PRECURSOR PHASE OF GAMMA-RAY BURSTS
High-energy neutrinos are promising cosmic messengers which can advance our understanding of the physics involved in the most extreme astrophysical phenomena and environments in the Universe. The
What is a globular cluster? An observational perspective
Globular clusters are large and dense agglomerate of stars. At variance with smaller clusters of stars, they exhibit signs of some chemical evolution. At least for this reason, they are intermediate
Covariant density functional theory input for r -process simulations in actinides and superheavy nuclei: The ground state and fission properties

NUCLEAR MASSES AND THEIR IMPACT IN R-PROCESS NUCLEOSYNTHESIS
During the present Thesis, the role of the nuclear masses in r-process nucleosynthesis calculations have been explored. In order to accomplish this goal, we have computed neutron capture rates in
Neutrino Emission from Supernovae
Supernovae are the most powerful cosmic sources of MeV neutrinos. These elementary particles play a crucial role when the evolution of a massive star is terminated by the collapse of its core to a
Neutrino-Driven Explosions
The question why and how core-collapse supernovae (SNe) explode is one of the central and most long-standing riddles of stellar astrophysics. A solution is crucial for deciphering the SN phenomenon,
Nucleosynthesis in thermonuclear supernovae
The explosion energy of thermonuclear (Type Ia) supernovae is derived from the difference in nuclear binding energy liberated in the explosive fusion of light 'fuel' nuclei, predominantly carbon and
