Hypergiant star

This adds a fictional yellow hypergiant star to size compare against the Solar System.

Now that's huge! But it would not be the largest star yet, because there are a few stars whose highest radii estimates put it at a size beyond Saturn's orbit. Not to mention the hypothetical "Quasi-Stars" that were said to exist back when the Universe was young

[Anthony_B_Russo10]

I had based its radius after HR 5171 A's radius.

Update: Now has Version 4.1 of my Planet 9 around the stars plus a Quasi-star.

Along with the major Edgeworth-Kuiper Belt Bodies.

Thanks
I've tried to make a Quasi-star addon with the black hole, but the black hole core wouldn't work.
I've also made a Thorne-Zytkow object named after Vlad Masters.

[Anthony_B_Russo10]

You could always define the black hole a planet and have its orbit be zero AU away from the star, which would put it a the center of the star.

[Joey P.]

Yes, they are now all supermassive black holes.

[Joey P.]

The Quasi-star in your recent update, for some reason, isn't even as luminous as the Sun. Quasi-stars were expected to be as bright as a small galaxy.

[Anthony_B_Russo10]

Update: now the Quasi-star's spectral classification is now O9.7V.

[Joey P.]

Why change the temperature to more than 10,000 Kelvin? Quasi-stars would have been only 6,000 Kelvin at most.

[Anthony_B_Russo10]

The quasi-star is now a G0V star.

[Joey P.]

Good
But what about the luminosity? It's okay if the brightness is at an apparent magnitude of 20.

[Anthony_B_Russo10]

Please look below for the actual 1.4 update for the Quasi-star.

The Quasi-star's luminosity is now high enough to be seen from the Solar System.

Update 1.5 adds Joey P.'s recently posted star.

And its core.

[Joey P.]

aww, you did it! Thanks

I can give you all of the Danny Phantom stars if you want
Not all of the characters have been converted into stars yet, but if anyone has an addon featuring real pulsars and black holes, then I might convert them into Danny Phantom ghosts.

[Joey P.]

(full Danny Phantom for Celestia forum post here)

[Anthony_B_Russo10]

I had updated it since you posted the code, anyway it helped the addon.

[Joey P.]

You're welcome.
What should you do next? Add the rest of the Danny Phantom characters converted into stars?
