(to be used with Lua Edu Tools) - HR diagram with fictional characters

This image is an edited version of that Hertzsprung-Russell diagram in Lua Edu Tools. It features characters from the American-Canadian TV shows Martha Speaks and Danny Phantom which is good for introducing children to the HR diagram and stellar evolution as they will realize that stellar lives are ...

Apology

Okay, I am very sorry guys, I made that account out of boredom.
This will never happen again.
So can we just move back to the topic? Thanks.

Re: Discover the oldest star in the universe

The oldest star is SMSS J031300.36-670839.3
it suits the first quotation - it was first observed by astronomers from Australia.

Re: How do you add more stellar classes in Celestia?

If you try to assign a star a class in an .stc file that is not O, B, A, F, G, K, M, R, N, S, W, white dwarf, neutron star, or black hole, it will be assigned the class ? and will be given the default A-class texture.

How do you add more stellar classes in Celestia?

How do you add more stellar classes in Celestia? I want to add other Wolf-Rayet subtypes and have separate textures for type B and late K-type stars. Thanks!

We should definitely make one around KIC 8462852.

Re: Celestia in Education

We also need to correct the star radii given within Celestia (for example, mu Cephei has a default of 3,870 solar radii as opposed to the widely accepted 1,420 solar radii)

Yes! I haven't been expecting this, but I think that is a major step to increasing social skills within our commune.

Re: IC 1101

I used an .stc to modify HIP 102276 (which is severely overestimated at 5,000 solar radii) into a Quasi-star.
The star that had 2,800 for maximum (actually 2,850) is KY Cygni.

Re: IC 1101

I know about Mu Cep. Many Italian astronomy websites have relied on Celestia and have accepted the 3,900 solar radii figure. I even saw a Brazilian Portuguese YouTube video that made Mu Cephei that big, and VY Canis Majoris at 7,720 sr! The largest possible star size (not including Quasi-stars) is 2...

Re: Looking for extra stellar textures

The ones already suggested are the ones I use. There are also (realistic) black-body star textures here:

Re: IC 1101

The Celestian size is wrong. IC 1101 is 5.8 million light years.

Actually, sadly for a software that is made to be education and 100% accurate, Celestia gets most sizes (especially that of stars) wrong.

Why are Y-type dwarfs not in Celestia? Also...

Y-type dwarfs are not in Celestia. They should considered a type of brown dwarf. If you try to create an entry for Y-type dwarfs in the celestia.cfg file, the star you choose as Y will have its spectral class set to "?" which generates a white star. Anyone know how to fix, or how to make e...
