Thermal shockwave; Skin/Core temperature
« on: November 26, 2016, 02:54:21 AM »
Lets say I turn up luminosity of our sun to 8 milion times of normal value.
Time scale is on seconds/minutes.
When we will be able to see planets being turned to plasma on one side and staying relatively cool for (short) time on unlit side?
It would be nice to see fire storm (if planet have atmosphere) and surface being molten progressively on unlit side.
 

Also surface and inner temperature should be separated.
Simplest model would be temperature linearly dropping from core (for example Earth, 6500 K) to surface (average temperature of 288 K for Earth).

Dang. You caught me....

Ok.
Lets see...

To increase the suns luminosity, you need to increase its temperature. To increase its temperature, the sun needs a hotter core. To gain a hotter core, the sun needs more mass (or hydrogen) to fuse.
So.....
To increase the suns luminosity, you need to increase the suns mass.
But, unfortunately, the SIM isn't that realistic.

But let's go with it.
Ok.
If the sun gained mass which did this, that a other, the earths surface would begin to heat up in 8 minutes.
Determining how hot the sun has now gotten, (let's assume it just became a hot blue star) the earth would vaporize in a matter of years, along with, Mercury, Venus, Luna (the moon), and possibly Mars, and most of the asteroid belt.

Jupiter, and it's moons, would warm up considerably.
Saturn, and it's moons, might be in the habitable zone of this new hot blue sun. And that's just being nice.
Saturn, and it's moons, could easily be much warmer.
Uranus (Urinus, better pronunciation) and Neptune would also warm up, but probably still be cold, or even freezing to us, but not as so as before.

Pluto, and it's 5 moons, along with the rest of the kiper belt objects, would warm up a little, and would be lit up in the blue glow of a hot star in the middle.
But definitely still be freezing, if not colder.

The inner planets would eventually vaporize in many years later, will the gas giants would dominate the solar system.
