The star Eta Carinae is a dying, unstable supergiant. It has sporadic episodes where its own light output rips its outer layers off and throws them off into space, revealing deeper, hotter parts of the stars innards in events known as eruptions. This causes the star's color appearance to bounce between orange (before the eruption) to bluish-white (after eruption). What pair of temperatures (in Kelvin) might account for Eta Carinae's color appearance change? a. 4100 K before the eruption and 9000
