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: The baseball will go farther because of Newton's law. The more mass an object as, the more force needed to move it. The bowling ball has more mass than a baseball so more force is needed to move it.
Explanation:
Answer:
B
Explanation:
The distance of the Goldilocks zone ensures that water on the terrestrial planet is maintained in the liquid phase. This is because the distance from the star ensure it receives enough sunlight to keep the planet warm but not too hot that the water exists as vapor. Water in its liquid form is essential for maintaining life like here on earth.
