- Good morning everyone!
- For today's discussion, I want to hear ideas from the class about Stellar Nucleosynthesis before we proceed to our lesson. Let's test if you've already read your books.
- Wow! Nice answers from Mr. Perez and Ms. Sanchez. Any more ideas?
- Base on what I've read Sir, I can say that Stellar nucleosynthesis is the process involving nuclear reactions through which fresh atomic nuclei are synthesized from pre existing nuclei or nucleons.
- Base also on what I've read in the book Sir, the importance of Stellar nucleosynthesis is that, it is the one that provides clues not only to stellar evolution but also to the space-time distribution of matter in the universe.
- Yes Sir! One of the strongest pieces of evidence for the theory of stellar nucleosynthesis Sir is the observation of absorption lines of the element Technetium from distant stars.
- Oh, thank you Mr. Santiago. Those sounds pretty cool! But are those enough?
- The elements of Stellar Nucleosynthesis Sir are hydrogen (H), carbon (C), nitrogen , oxygen (O), phosphorous (P), sulfur (S), chlorine (Cl), sodium from natrium (Na), magnesium (Mg), potassium from kalium (K), calcium (Ca), and iron from ferrum (Fe).
- I have some additional information Sir.
- Okay Ms. Cruz. The floor is yours now.
- Very good Mr. Perez!You have a lot of ideas today. How about you Ms. Cruz?You're so quiet.
- Actually sir, I also have an idea sir.
- Wow! All of your answers are correct! I didn't expect that you have those ideas. Great job students!
- The situation that is required to stellar nucleosynthesis is when the H-exhausted core reaches temperatures of 100–200 millions K (with higher temperatures corresponding to higher stellar masses), He fusion begins. And at that point the stellar nucleosynthesis will occur.
