    Elements Origin
AI Thread Summary
The discussion focuses on identifying the primary sources of various elements in the universe, specifically silicon, lithium, bismuth, nickel, and uranium. Participants debate the processes responsible for their formation, including primordial nucleosynthesis, fusion in low and high-mass stars, and neutron capture in supernovae. Clarifications are made regarding the correct associations, with some suggesting that silicon and nickel are produced in high-mass stars rather than low-mass stars. The conversation highlights the complexity of nucleosynthesis and the importance of accurate classification in astrophysics. Overall, the thread emphasizes the need for precise understanding of stellar processes in element formation.

By choosing among the following five options, what is the main source in the universe for the origin of the elements : silicon, lithium, bismuth, nickel and uranium?

Primordial nucleosynthesis – fusion in core of low-mass stars – fusion in core of high-mass stars – slow neutron capture in high mass-stars - rapid neutron capture in supernovae.

Thanks

Sorry, next time I will choose the right forum.
The following is what I think is the right answer but I'd like to be confirmed.

silicon = Fusion in core of low-mass star
lithium = Primordial nucleosynthesis
bismuth = Low neutron capture in high mass-stars
nickel = Fusion in core of low-mass star
uranium = Rapid neutron capture in supernovae

Thanks!
 
For nickel I think you mean fusion in the core of a HIGH mass star. Also, isn't silicon one of the last elements produced in high mass stars and not low mass stars? I'm not formally educated in astrophysics so I could be wrong.
 

Thread '3I/ATLAS, Interstellar Comet'

3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
