IRAS 13208-6020 is a preplanetary nebula in the Constellation Centaurus. are formed from material that is shed by a central star. It was first discovered and observed during the IRAS Sky Survey. This is a relatively short-lived phenomenon that gives astronomers an opportunity to watch the early stages of planetary nebula formation, hence the name protoplanetary, or preplanetary nebula[1].
Characteristics
IRAS 13208-6020 has a very clear bipolar form, with two very similar outflows of material in opposite directions and a dusty ring around the star. It does not shine, but is instead illuminated by light from the central star. IRAS 13208-6020 is not currently in the planetary nebula stage, and it is assumed to be very early in its lifespan[2].
