r-process nucleosynthesis: connecting rare-isotope beam facilities with the cosmos [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2018
This is an exciting time for the study of r-process nucleosynthesis. Recently, a neutron star merger GW170817 was observed in extraordinary detail with gravitational waves and electromagnetic radiation from radio to gamma rays.

The first direct double neutron star merger detection: Implications for cosmic nucleosynthesis [PDF]

open access: yesAstronomy & Astrophysics, 2017
Context. The astrophysical r-process site where about half of the elements, heavier than iron are produced, has been a puzzle for several decades. Here we discuss the role of one of the leading ideas – neutron star mergers (NSMs) – in the light of the ...

Observing the signatures of AGB s-process nucleosynthesis in planetary nebulae: An origins story

open access: yesFrontiers in Astronomy and Space Sciences, 2022
I relate an anecdotal history of the beginnings of a new initiative in studies of the chemical composition of planetary nebulae: namely, investigating abundances of elements beyond the iron-peak through infrared spectroscopy.

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

open access: yesAstronomische 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 ...

Nuclear reactions involving light elements & BBN [PDF]

open access: yesEPJ Web of Conferences
Light elements play a key role in different scenario in astrophysics, ranging from primordial nucleosynthesis up to stellar nucleosynthesis and cosmic ray nucleosynthesis.

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

open access: yesJournal 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.

Big Bang Nucleosynthesis Constraints on f (T, TG) Gravity

open access: yesUniverse, 2022
We confront f(T,TG) gravity, with big bang nucleosynthesis (BBN) requirements. The former is obtained using both the torsion scalar, as well as the teleparallel equivalent of the Gauss–Bonnet term, in the Lagrangian, resulting to modified Friedmann ...

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

open access: yesAstronomische 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.
