Title: massoutburst of Eta Carinae shatters rings and bring them into bizarr orbit
Post by: Andreas on February 20, 2009, 05:05:27 PM
I created Eta Carinae and placed a dusk disk around him. Because of its gigantic mass, has Eta Carinae huge outbursts. The matter burst out and then fall back on its surface (the outbursts are about 3-4 times the mass of our sun).

I simulated such an outburst with low esc. velocity. So the mass fall down on Eta Carinae in same seconds. But it shattered the disk and then after time, it formed them into really amazing way.

I made a video and uploaded it on youtube.

Him? It's a person?  ;D just had to do that.

...the word star (in german Stern) is a male term in german language. So in german its treated like a person...

Yeah. That looks awesome.

Did you use Geosynchronous rings to create the particles in orbit around the star?



And as an aside, I'd really appropriate a link back to this site in the comments for the video so people can know how you made the video.

No, thats the weird thing. it was a normal ring 3-5 radius of eta cariane. Then as i simulated the "Burst" the ring "shaked". It was like its pulsing. And then formed that way.

How did you simulate the burst? I can't understant ::)  :)

very easy, just let the Star explode with low speed, so the mass fall back on it.

The "Explode" command in Universe Sandbox breaks a body into multiple bodies. If the explode velocity of these bodies is low enough then the mass of these pieces will pull them back together again.

umm no...

Eta Carinae is a massive star. The most massive known. It has an estimated mass of  100-120 suns.

Because of that mass, it is not very stable. The fusion process in its core is 5.000.000 times more active, then in our sun.
From time to time, Eta Carinae has gigantic "outbursts" of matter. It almost rip the star in pieces, but somehow it always survived till yet.

There are more massive! VV Cephei and VY Canis MAjoris

Post by: Andreas on February 22, 2009, 02:14:14 PM
ha ha ha no. It seems you know nothing about stars at all. VV Cephei has only 24-40 times the mass of the sun.
Canis Majoranis is only 30-40 times the mass of sun. Even put together they donīt have the mass of Eta Carinae.

VV Cephei and Canis Majoranis are just bloated.

You said to NeutronStar:
It seems you know nothing about stars at all.

Let's be careful about making sweeping accusations that are untrue. :)

He may have been incorrect about which star is the largest (by mass), but he did name some of the other largest stars (by diameter) known to humanity.

In short... Let's all be nice.

yeah, but it didn't. It looked like two stars crashed head on and when they did they each let off a big outburtst of gas.

If Eta Carinae has an outburst what happen

Post by: Andreas on March 11, 2009, 05:51:44 PM
Well an outburst from Eta Carinae is like a regular Flare on our sun. The only difference is, that an eta carinae outburst is as big as an average super nova.

Quote from: Andreas

Eta Carinae is a massive star. The most massive known. It has an estimated mass of  100-120 suns.

Recent observations confirmed the Brazilian astronomer's Augusto Daminelli model that proposed that Eta Carinae would be a double star, and no a single star, with apparent total mass among 100 - 120 times the mass of our Sun.

Due to its duplicity Eta Carinae shows spectroscopics eclipses every 5,52 years, what was confirmed by observations done in 2003 and 2008.

Like this Eta Carinae actually would be two stars with masses of 80 and 30 solar masses.

Note: a group of brasilian amateur astronomers develop an homemade spectrograph and can register the spectroscopic eclipse of Eta CArinae in 2003. The data collected by this amteur astronomers are used in the final papaer of the confirmation of the duplicity of the Eta Carinae:

The more massive star in our galaxy is a star in NGC 3603.

It's a star with 116 solar masses orbited by a companion with 89 solar masses .
