WOOO untrue!!! it all depends on the stars Mass!! IF ITS VERY HEAVY (4 times or more our sun), Then it will take approximatively 100 million years to die! EXCEPT, that those heavy stars change very often their nuclear reactions so they can sustain all their mass.
In conclusion, if that star is a HEAVY star, and it is in its final stage, it could have changed A LOT in a thousands of years, or even less. SO, it could well be the same star but that is in its final stage! (because reactions goes faster in the end)
OR (2nd theory, i think thats the best) it could have gone from "super red giant star" to "white dwarf' during that time, which would explain why its not the same color anymore.
(ok now, if the time laps is very small, a planet nebula could have put that star from a "super red giant star" to a " white dwarf" in no time)
Very, very untrue. Here's a link (doesn't work in hyperlink):

As stated in the first sentence after the introduction, the sun's lifecycle takes anywhere from a few million to a few billion years. The sun just doesn't go from red giant to white dwarf, there are stages in between that take a very long time. The time elapse from the attack on Reach (Aug 30, 2552) and MC floating in space (Mar 3, 2553) is around 6 months. Do you think that sun could go through multiple stages throughout its lifetime in a matter of months that would take the average star millions of years?
Theory disproven.
