Properties and Composition of Magnetized Nuclei

Particles, 2020
The properties and mass distribution of the ultramagnetized atomic nuclei which arise in heavy-ion collisions and magnetar crusts, during Type II supernova explosions and neutron star mergers are analyzed.

Triggering carbon burning in stars

Astronomy & Astrophysics
Context. Carbon burning determines the destiny of stars with masses higher than ≈8 M⊙ and mass-accreting white dwarfs (WDs) in close binary systems. For this reason, in order to understand several astrophysical phenomena it is necessary to understand ...

Can We Draw Conclusions on Supernova Shock Wave Propagation Using Short‐Lived Radioactive Isotopes?

Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT We run a three‐dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn (exclusively produced from type Ia supernovae, SNIa), 60Fe (exclusively produced from core‐collapse supernovae, CCSNe), 182Hf (exclusively produced from intermediate mass stars, IMSs), and 244Pu (exclusively produced from neutron star mergers ...

An Introduction to Primordial Nucleosynthesis

, 2006
International audiencePrimordial nucleosynthesis is one of the three observational evidences for the Big Bang model. Even though they span a range of nine orders of magnitude, there is indeed a good overall agreement between primordial abundances of ^4He,

Methyltransferase‐Like 3‐Mediated N6‐Methyladenosine Modification on RNAs: A Novel Perspective for the Pathogenesis and Treatment of Bone Diseases

Journal of Cellular and Molecular Medicine, Volume 29, Issue 5, March 2025.
ABSTRACT Osteoarthritis, osteoporosis, and osteosarcoma are prevalent osseous pathologies associated with the aberrant functionality of chondrocytes, osteoclasts, and osteoblasts, respectively. These conditions frequently exhibit therapeutic resistance and possess a high mortality risk, thus representing substantial health threats.

Neutrino Induced Nucleosynthesis of Radioactive Nuclei in Core-Collapse Supernovae [PDF]

, 2017
We study the impact of neutrino-nucleus reactions on the nucleosynthesis in shock- heated supernova ejecta. Nucleosynthesis calculations with an extensivνe set of neutrino-induced reactions are performed, including updated insights into expected neutrino

Mass‐Loss, Composition and Observational Signatures of Stellar Winds From X‐Ray Bursts

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT X‐Ray bursts (XRBs) are powerful thermonuclear events on the surface of accreting neutron stars (NSs), which can synthesize intermediate‐mass elements. Although the high surface gravity prevents an explosive ejection, a small fraction of the envelope may be ejected by radiation‐driven winds.
