Steps in the Life Cycle of a Star Pages 707-714

What step of the life cycle am I? Burns hydrogen If a nearby star was in this phase, it would be brighter than the sun. No larger than earth, but have more mass than the sun. Emits X-rays Energy heats and expands it’s outer layer. Not yet hot enough for nuclear fusion. Gives off pulses of radio waves For reasons unknown they become dense enough to contract. White dwarfs heat the gasses of a ____ causing it to glow. Massive stars pass through this stage very rapidly.

What step of the life cycle am I? Main sequence OR Massive Supernova White dwarf Black hole Red Giant Protostar Pulsar/Neutron Star Nebula Planetary Nebula Super Red Giant.
