Compare the elements in an early Protostar and those in a young star formed from star dust of older stars
Since this is not my area of expertise, I searched Google under the key words "protostar elements young" to get these possible sources:

I hope this helps. Thanks for asking.

To compare the elements in an early Protostar and those in a young star formed from star dust of older stars, we need to understand the process of stellar evolution. Here's how you can compare the elements:
1. Start by researching the formation of a protostar. A protostar is a dense cloud of gas and dust that collapses under its own gravity, eventually forming a star. Look for sources that explain the formation process and the composition of a protostar.
2. Once you have an understanding of protostars, research the process of star formation from the remnants of older stars. This occurs when supernova explosions distribute heavy elements into space, which then serve as the building blocks for new stars. Look for sources that discuss the recycling of materials in interstellar space and their incorporation into newly forming stars.
3. Compare the elements present in a protostar with those in a young star formed from older star dust. Look for information on the chemical composition of both types of stars. Pay attention to the abundance of elements such as hydrogen, helium, carbon, oxygen, nitrogen, and heavier elements.
4. Analyze the differences in element abundance between the two types of stars. Consider factors such as the initial composition of the protostar compared to the enriched composition of a star formed from older star debris. Also, look for information on the processes that can alter the element abundance during the formation of a star.
Remember to use reliable sources such as scientific journals, academic websites, and reputable astronomy organizations. This will ensure that the information you gather is accurate and up-to-date.
