Question about Stardestroyer Shields

Omega-13 · Post by **Omega-13** » 2004-03-29 01:38am

Hi,
I'm writing a fanfic and i'm trying to get it technically accurate,
how close have we seen a stardestroyer or superstardestroyer get to a star?

how close can it get before the shields fail, and it melts

IIRC, in one of the comics, it was so close to a massive black hole that there was a million-G differential between the front and the back end.

Correct me if i'm wrong, but didnt a star destroyer hit a SSD at FTL speeds, and not even scratch the paint? That has to be prety impressive. That is, if i remember correctly...

thats quite impressive
especially considering the Vong can rip the shields right off a stardestroyer in the novels

so saying that would it not be over written by official? or do comics and novels have the same level?

no they just came OUT of hyperspace, and 3 collided with the top of the SSD, it destroyed the shield generator and needed an overhaul, but the ssd survived, thats a lot of tonnage, maybe over written by canon in ESB, even though not the same ship, i think we're talking hundreds of millions of times difference, i'm not sure of course, i'm just looking to see if there are contradictions

It is unfortunate that we don't know the mass of the black hole. Do we know more about how it came to be, so that we might come to a distance from the black hole?

I guess we could just assume a couple stellar masses, if it were a normal bog-standard black hole...

So the shield can protect against gravity aswell?
How did the SSD ever get AWAY from the blackhole,

The ISD in question was not able to get away from the black hole; its inertial compensators failed.

I don't see where black holes come into this; he was asking about stars and heat.

Pretty damn close, IIRC. Didn't one get pretty banged up going in to attack Nkellon without a shieldship or something? I'm not sure how close that is, but its as least as close as Mercury to the sun, and probably a little closer.

The ISD was large enough to survive that for a few minutes, but it had to be stripped from sensors (and weaponry if I remember well), and required repairs after the mission. Smaller ships (like Katanas) would have been melted. Lando's city would have been able to survive that sunshine only by burrying itself.

Rogue 9 · Post by **Rogue 9** » 2004-03-29 05:11am

Yeah, well there's a strike against. Anybody know how close Nkellon's orbit is? (I'm pretty sure I'm spelling that wrong, but the real name escapes me at the moment.)

Connor MacLeod · Post by **Connor MacLeod** » 2004-03-29 05:16am

Nkllon was an unusual situation; Mike and Wayne have pages dedicated to that, as I recall. Anyyhow, to figure this out all you really need is the cross-section of an ISD, its energy handling capacities (at least energgy-dissipation and/or the energy absorption capacity) and the intensities of solar energy at varying distances

The shield generator destroyed ? How can you be sure of that ?

Spanky The Dolphin · Post by **Spanky The Dolphin** » 2004-03-29 11:16am

Because the shields failed from the impact.

Howedar · Post by **Howedar** » 2004-03-29 12:03pm

That doesn't mean the generator was destroyed, necessarily.

Ok, astrophysics 101 time!

How do stars give off heat?

Heat, identified by a difference in temperature, is the result of radiation interacting via photo or electrostatic interactions, with the target material. This increases the average random kinetic energy of the materials atoms, and thus the difference in temperature, therefore sensing heat.

So radiation is a big part here.

Now, who knows what black holes and neutron stars give out a shitton of? If you said RADIATION, you are right!

That's how black holes come into play.

In Heir to the Empire a Star Destroyer goes right next to a star, which normaly takes sheildships although the ship did take serious damage

President Sharky · Post by **President Sharky** » 2004-04-02 01:51am

The Heir to the Empire comic shows that Nkllon was considerably close to the star Athega, in the photo, I can estimate the ratio between the star and planet at the perspective of the drawing was about 60:1. This is during the Millennium Falcon's approach to Nkllon with the shieldship. The planet must be extremely close to the sun, especially if it can melt off Star Destroyer armour. The star must also be very young for it to be so hot.
