EHe stars are an exceptionally rare class of evolved stars that contain almost no hydrogen, the most abundant element in the ...

Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.

Physicists have revealed a new understanding of nucleosynthesis in stars, providing insight into the role massive stars play in the evolution of the Milky Way and the origins of the Solar System.

Scientists have known for a long time that the heavy elements in stars, such as barium, lanthanum and cesium, are created through rapid and slow nucleosynthesis processes. Nucleosynthesis is the ...

The Big Bang nucleosynthesis ladder was thereby missing ... of the higher elements beyond helium were produced in red giant stars. Over the course of a decade, from the mid-1940s to the mid ...

the neutron star accretes mass via an accretion disk at a very high rate, and the energetic and dense jets that are produced can provide proper conditions for r-process nucleosynthesis.

What differentiates a star from even the largest ... barrier and fusing two nuclei into one in a process called stellar nucleosynthesis. The energy that had been holding the atoms apart is ...

Which stars form which elements, and how those elements form, is what stellar evolution and nucleosynthesis aims to understand. Stellar evolution looks at how stars change their structure and ...

As massive stars collapse into black holes ... Do you have a question about nucleosynthesis? Let us know via [email protected].

In the search for conditions suitable for these elements via "nucleosynthesis," a Los Alamos ... and surrounding cocoon emerging from collapsed stars. "The creation of heavy elements such as ...

The study challenges the present understanding of nucleosynthesis in stars. “Our next study may concentrate on helium-flash nucleosynthesis and how lithium escapes from destruction in the ...

The ratio of oxygen-17 to oxygen-18 provides evidence of nucleosynthesis in stars, as high levels of oxygen-18 are only produced in supernovae. Some grains in Ryugu had an oxygen-17/18 ratio that ...
