200,000 Degree Star Found at Center of NGC 6302
Astronomers at The University of Manchester's Jodrell Bank Centre for Astrophysics have discovered one of the hottest stars in the Galaxy. With a surface temperature of around 200,000 degrees, it is 35 times hotter than the Sun. The star was found at the center of NGC 6302, also known as the Bug or the Butterfly Nebula.

Considering our sun is about 6000 degrees F, but the corona can be 150 times hotter, I'm trying to figure out what the structure of this star must be. If indeed the star's surface is this hot, I am wondering where it and the Bug Nebula would fit on a chronological scale of other nebula spawning "dying" stars.

"The central star, which up to now could not be seen because it is hidden within a doughnut-shaped ring of dust, appears as a dark band pinching the nebula in the center." In this photo, I can see the little dark band. What does it mean when the authors say that they have seen the star? Is seeing the dust band seeing the star? :S
