White Giant

A White Giant star-is such an anomaly possible? How hot would it burn? Could life exist on planets orbitting such a star?

Rigel and Deneb are white giants. Their temperature is around 10,000K. Life is almost impossible there because life expectancy of such stars is only a couple of million years. This is probably too short for life coming into existence.

But because you speak about an 'anomaly' I assume that you thought of white giants with the same core reactions as in white dwarfs? Such stars don't exist because they would immediately collapse and either become a normal star with nuclear fusion or a black hole -- depending on their chemical composition.
