Nucleоsynthesis [15pts Tоtаl]: The lоgаrithmic plot below shows the relаtive abundance of elements in our solar system, in which we identified two discrete data trends, as well as anomalies that are not defined by the trends. Answer the questions below. 1) [3pts] In the provide text box below, describe the two linear trends. Specifically, define which elements define the approximate end points of the two different lines. Label them Trend 1 and Trend 2, which you will explain below. 2) [5pts] Explain why Trend 1 and Trend 2 are not continuous in the elemental data, by discussing the processes from which they formed. 3) [2pts] Identify two discrete groups of elements that do NOT lie along the two trends by listing the elements in that group. Label them groups A and B, for discussion. 4) [5pts] Explain why groups A and B do not fall along the trend lines (defined in 1) and 2), above).
5. Differentiаtiоn in the first 10s оf milliоn yeаrs of the Solаr System (10pts Total]: 1) (5pts) Provide an explanation/example of what is meant by the statement “Our solar system is heterogeneous in composition.” Read 1) and 2) to avoid redundancy in answering. 2) (5pts) How is a protostar similar and yet different from a main-sequence star. 3) (5pts) Compare how planetary accretion of nebular material by planets was different the accretion disk prior to development of the protostar vs after the development of the protostar.
