Science fiction ....: sun explodes
09/13/08 at 23:41:44
 
( something I always wanted to simulate ).  
Suppose for some reason our sun looses at a given time 0.1% of its mass by means of a radial explosion .  
 
The simulation starts with 180 solar filaments , each having 1.09e+25 kg of mass and diameter of 52754 km ( having a density of 1.40 ) .  
The bodies start at a radius of 4533,927 km from the suns center and are arranged equidistant on this circle , so their mutual distance is 3 times  their diameter ( can be compared with a pearl chain) .  
They start with a velocity outwards of 252.664 km/s , about 1/3 of the escape velocity at suns surface .  
How do this system acts ?  
In annex the simulation file , starting with a timestep of 0.02 sec.

In frames of 4 hours apart the explosion shows up as following :  
After a rapid inflation of the explosion front one can see a slowing down of the filaments .  
The filaments  also tend to coglomerate as their radial speed decreases and mutual atttraction dominates .  
At the left a couple of  bodies were ( not intentionally ) given a small offset in radial initial velocity . They combine very soon after the explosion .  
It's interesting to see how Mercury survives when the schokwave passes.  
The wave comes to a maximum distance somewhere half the way between Mercury and Venus and then collapses again.

That's interesting, I didn't think the wave would collapse back like that!

Increasing it's initial velocity a little will it bring much further ( fi : v + 2% might the wave bring beyond Jupiter ) , till there is a point ( v+4% ? ) where the bodies leave the solar system .  
It' s funny to seen how small initial deviatons grow up to different patterns ( see left and right ) .
