The Hertzsprung-Russell diagram is one of the most important tools in the study of stellar evolution. Developed independently in the early 1900's by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the color of stars against their absolute magnitude
Depending on its initial mass, every star goes through specific evolutionary stages dictated by its internal structure and how it produces energy. Each of these stages corresponds to a change in the temperature and luminosity of the star, which can be seen to move to different regions on the HR diagram as it evolves. This reveals the true power of the HR diagram – astronomers can know a star’s internal structure and evolutionary stage simply by determining its position in the diagram.
The Hertzsprung-Russell diagram the various stages of stellar evolution. By far the most prominent feature is the main sequence (grey), which runs from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) of the diagram. The giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it.

Answer:
To what extent is the chemical composition and other abiotic factors of Louisiana's waters contributing to the proliferation of Brown Marsh?
From the question above, we have factors that are identifiable as the object of the research.
They are:
- The chemical composition of Louisiana's waters
- Other abiotic factors (that is other non-living factors)
The second option here, if it is too vast, may be limited by the researcher to a maximum of three factors to ensure that the research questions remains feasible.
Cheers!
