How long does it take Sirius to just barely move off the Main Sequence?

Questions: Working with a star twice our Sun’s mass (Remember that mass is the physical space an object occupies, the density is how much mass per volume is present there—two different but related terms). An example is Sirius, the dog star, is a nearby star (8.6 light years away) that is about twice our Sun’s mass. 5. On the lower left of the simulation is the option to set the mass to 2 times our Sun’s; do that by choosing 2X. Is it still on the Main Sequence? If so, what are it’s temperature (x-axis), brightness (y-axis), stage, and mass? 6. How long does it take Sirius 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? 7. Stop the simulation or click on the dotted line at the highest temperature (farthest left of the path)–what is the temperature here? Why? 8. At the end of the life cycle path, what how old is Sirius and what are its measurements
