Author Topic: massoutburst of Eta Carinae shatters rings and bring them into bizarr orbit (Read 26743 times)

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?

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...

i saw your video it's cool

Dan Dixon · « **Reply #6 on:** February 21, 2009, 11:39:52 AM »

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

Andreas · « **Reply #9 on:** February 21, 2009, 03:45:01 PM »

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.

like one of saturn's moons

Andreas · « **Reply #15 on:** February 22, 2009, 10:26:14 AM »

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

Andreas · « **Reply #17 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 donÂ´t have the mass of Eta Carinae.

VV Cephei and Canis Majoranis are just bloated.

it looked like it collided with another star

You said to NeutronStar:

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.

(And the next update will have Eta Carinae in the preset list for New Bodies.)

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.

Naru523 · « **Reply #23 on:** March 03, 2009, 10:02:27 PM »

Wow. I wonder if 8 stars orbiting eachother

Scienctists say that they found 7 stars orbiting their selves.

Do you have dates to recreate the system?? It's too interesting

Andreas · « **Reply #25 on:** March 07, 2009, 05:15:43 PM »

yes, iÂ´ll post it later

You can see these star sizes (not made by me)

If Eta Carinae has an outburst what happen

Andreas · « **Reply #29 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.
