Geophysical Research Letters, Volume 50, Issue 4, 28 February 2023., 2023 Abstract We employed MC‐ICP‐MS to measure the mass‐dependent Ca isotope compositions of Vesta‐related meteorites. Eucrites and diogenites show distinct Ca isotope compositions, which is caused by crystallization of isotopically heavy orthopyroxene. The Ca isotope data support a model where the two lithologies are linked, where the diogenites, mainly ...

Nucleosynthesis and Kilonovae from Strange Star Mergers
Universe, 2019 In this talk, we summarize the work in progress toward a full characterization of strange star−strange star (SS−SS) mergers related to the GW/GRB/kilonova events.

Dark Nuclei I: Cosmology and Indirect Detection [PDF]
, 2014 In a companion paper (to be presented), lattice field theory methods are used to show that in two-color, two-flavor QCD there are stable nuclear states in the spectrum.

Origin of 182W Anomalies in Ocean Island Basalts
Geochemistry, Geophysics, Geosystems, Volume 24, Issue 2, February 2023., 2023 Abstract Ocean island basalts (OIB) show variable 182W deficits that have been attributed to either early differentiation of the mantle or core‐mantle interaction. However, 182W variations may also reflect nucleosynthetic isotope heterogeneity inherited from Earth's building material, which would be evident from correlated 182W and 183W anomalies. Some

Núcleos exóticos e síntese dos elementos químicos
Química Nova, 2012 We have around ninety chemical elements available in nature, which were produced mainly by nuclear reactions inside stars. The fusion reactions are the main synthesis process which generates the light and intermediate masses elements.

Experiments probing clustering effects in explosive nucleosynthesis
Frontiers in Physics, 2023 Nuclear clustering affects the nucleosynthesis occurring in a number of astrophysical environments. Highly-clusterized nuclear states typically occur near particle thresholds and therefore can produce dramatic impacts on the nuclear reaction rates.

Cosmological and astrophysical bounds on a heavy sterile neutrino and the KARMEN anomaly [PDF]
, 2000 Constraints on the lifetime of the heavy sterile neutrino, that was proposed as a possible interpretation of the KARMEN anomaly, are derived from primordial nucleosynthesis and SN 1987A.

Screening Effects in Stars and in the Laboratory
Frontiers in Physics, 2022 Nuclear reactions are the driver of the evolution of many astrophysical objects. In the astrophysical environment their respective reaction rates are, however, modified due to the presence of other charges.

Reheating Temperature and Gauge Mediation Models of Supersymmetry Breaking [PDF]
, 2009 For supersymmetric theories with gravitino dark matter, the maximal reheating temperature consistent with big bang nucleosynthesis bounds arises when the physical gaugino masses are degenerate.
