Double shell burning stage never reaches equilibrium and this is because like we said, the fusion rate periodically spikes upward in a series of thermal pulses and due to these spike some outer layers are lost to space. Therefore, it can never reach equilibrium.

Two questions why do they call it the zombie phase and if the core is getting bigger and the outer surface is getting smaller in the first phase then how does it go through so many stages without exploding already?
Since we did not reference this phase we are not exactly sure on why they call it a zombie phase. It's due to the certain stages and the chemical reactions it goes through during each phase.
Said by Universe Today in an article on December 22, 2015, "In 1.1 billion years from now, the Sun will be 10% brighter than it is today, and this increase in luminosity will also mean an increase in heat energy, which Earth’s atmosphere will absorb"(Williams 2015). This is the most recent information I could find, I know this might not fully answer your question but I hope it can lead you to some what of an understanding of the question.

DeleteHow do they measure a white dwarf's weight compared to Earth?
ReplyDeleteThis was an inaccuracy on our part in our presentation, I'm sorry for the confusion.
DeleteAt what point in the sun's life cycle will life as we know it be affected?

DeleteIf our sun is currently considered a low mass star, how many billions of years will it take to become a red giant?
ReplyDeleteWell, our sun is currently at 4 billion years and it is said that a the sun becomes a red giant at approximately 10 billion years.
