  • READY?!?1?!

  • stupidest looking star ever.

  • are there any colonies nearby?

  • looks more like a slow spinning skinned potato :\

  • i thought vega was that flat...?

  • Isn't Regulus blue?

  • @drtony999

    Yes it is. I've assumed that the band of gravity darkening would be cooler, and would appear yellower compared to the poles.

    Perhaps a better way would be to show the poles bluer and the equator white, but that makes the equator appear brighter rather than dimmer.

  • a cosmic egg?

  • But i thought stars didn't spin around.

  • wt?

    a egg :D

  • If the star spins too fast, portions of its chromosphere might disintegrate and splash out...

  • sometiems i swear regulus loks brighter than sirius but i know that isn't true

    sometimes even pollux looks brighter, but it is more yellowy and siruis is more whitis blue

  • This is just a 3D simulation from the software "Celestia".

    All stars in Celestia have the same spot-texture, just the size and color are varying.

    There's not much sense uploading it to youtube...

  • Yes and no; I added a mesh to make Regulus oblate, and made the equator cooler (more yellow) in accordance with its predicted appearance- so it is not quite a straightforward Celestia image. But it is reasonably straighforward, yes. Check my Dschubba and Betelgeuse videos for slighly more complex Celestia star models I've made.

  • The huge force is angular momentum, a result of this stars extremely rapid rotation.

    Whay does it spin so fast? No-one really knows (though there are theories)

  • I can't beleive a star like that could exist unless some huge force is deforming it after it has a normal formation , the round shape of moons planet stars is due to their gravity , the gavity needed to make a perfect round shape is less than the moons one at the same time to have a star the gravity needed to alow nuclear fusion i was bigger than the than brown dwarf(compared to jupiter it is way bigger) which result to the fact that start can't only have a round shape in general....

  • I always wondered about 2 things with astronomy, 1. if your looking threw a telescope whether on land or in space- and lets say a piece of dust or rock floats or is in the view of where you are looking, like a person walking in front of binoculars, zooming so close wouldnt you eventually always zoom in a piece of dust or debris somewhere along the billions of miles? 2. if we can see billions of light years with telescopes why cant we see things better in closer systems like planets and such

  • no i am in no way being cheeky, honest questions i dont understand about astronomy so please ovoid flaming this persons channel

  • Things such as planets and debris don't emit light, so it is hard or impossible to see them with telescopes at the moment. We cannot just "zoom in" and keep "zooming in", telescopes need mirrors to work, and the larger the mirror is and the longer the focal length the better picture you will get.

  • GIANT EGG ;D

  • Neat star

  • Hahaha, lol, an egg-shaped sun, that would be realy funny! :D:D

  • Yea... its a FUNNY star :D

  • very exaggerated model

  • I'm guessing that a star like that wouldn't have planets. Not sure why I think so, but...

  • Hmmm, well it would be nice to know wouldn't it?

  • It would indeed.

  • IS THIS AN scooty allan OF THAT MENTOS the fresh maker THING

  • is it me or is that star spinning so fast that it's oval?

  • Yes; several A and B class stars spin this fast. The equator of such stars is slightly cooler than the poles because it is further away from the core.

  • but there are links to the Altair actual imaging and analogous model, fast spinning & similarly oblated. The image files seem locked now, but the academic paper is there:

    astro-dot-lsa-dot-umich-dot-ed­u-fwd-~monnier-fwd-Publication­s-fwd-Research-dot-html

    or try eurekalert*org search: Altair

    It had great motion swf video corresponding to the 'acutal' inferometrically constructed image.

  • Hi 'Kemmerer, A very striking image of Regulus. But is what we are seeing a computer simulation or the real object? Thanks. (from "Cefnonn" = a village in Wales if you're wondereing what the word signifies)

  • It is an image made using Celestia, a free universe modelling program.

    I have altered the shape of the star and changed the texture slightly to reflect current ideas about the shape and luminosity.

  • Not from Regulus; but other stars do suffer loss from the equator- see my other video of Dschubba.

  • Not from Regulus; but other stars do suffer loss from the equator- see my other video of Dschubba.

  • Very flat star! Doesn't matter escape from the ecuator?
