At the end of the life cycle path, what how old is the Sun and what are its measurements?

EXPLORING THE H-R DIAGRAM & LIFE CYCLES OF STARS In your browser, open this link: https://starinabox.lco.global/ 1 This is a simulation called Star In A Box, and will allow us to explore the H-R diagram and how our Sun fits into it. Remember that on the H-R diagram, the y-axis gets brighter as you go up (increase), and the x-axis gets hotter as you go from right to left (not an obvious thing to notice). Your display should look like this: If not, make sure you have clicked on the “Open the Lid” option on the lower right of the image. This first screen will show how our Sun looks on the H-R diagram. Click on the Information option at the top right of the image to see how it all works. Then, look at the symbols located above the Play button area: 2 These will tell you, any time you stop the simulation, what the size (in comparison to our Sun), temperature, brightness, stage, and mass of the star you’re looking at. Instructions: 1. Click on the speed option and choose ‘Slow” at the lower right area. This will slow down the life cycle of our Sun so you can answer our questions. 2. Click the Play button to start the simulation, and answer the following questions. 3. Take screen captures as you go—you’ll need at least 1 for each Part we do. Questions: Working with the Sun 1. At the beginning of the simulation, locate our Sun; is it on the Main Sequence? If yes, look at the symbols above the ‘Play’ button and click on those; what are it’s temperature (x-axis), brightness (y-axis), stage, and mass? Make sure you use the correct units, for example, temperature is measured in degrees Kelvin (ºK). 2. How long does it take our Sun to just barely move off the Main Sequence (for example, 5000 million years is 5 billion years, 10,000 would be 10 billion years)? At this point, what are the measurements of temperature, brightness, stage, and mass? 3. Stop the simulation or click on the dotted line at the highest temperature (farthest left of the path)–what is the temperature here? Why? 4. At the end of the life cycle path, what how old is the Sun and what are its measurements
