Pretty sure if you are 4ls away from a Brown dwarf and 4 away from an Oclass then you will be hotter at the Oclass
Why are Class L brown dwarves (dwarfs) just as hot as Class O blue Giants?

426 can make a big shift in classification tho. In scale of stars and our feeble existence its just peanuts, but 426 deg can make or break if a star will go kaboom or just 'poof'.
But distance is important, not sure why it shouldn't. You are confusing me!
Two stars, one twice the radius.
Other twice as far.
Both same surface temperature (I.e. both class M 3000K).
Both look the same size on the screen.
Both irradiate you with *very similar* amounts of radiation.
YET IN ELITE, a class Y star has stronger heating properties to an O class star *WHICH LOOKS THE SAME SIZE ON THE SCREEN* ← capitals for emphasis, not volume ;-)

Only up to a point, the inverse square law will start to apply as you get further away and the stars act more like point sources.
Edit: actually much more complicated - the bigger star must be generating more energy to make it bigger but I'm not sure that can happen and still have the same surface temp and class.

Not saying that distance is not important.
Just saying that two stars that LOOK THE SAME SIZE on the screen in elite should make you EQUALLY HOT only if they have the same surface temperature. (Unless you've crashed into the green line or whatever signifies their atmosphere/corona.)
About scanning tho, logic goes out of the window here - you can scan a gas giant at best some 1K+ range, but in case of these "dwarves" (which in reality have stronger emissions and so on) scan from 500 or so..
But all that ignores density and heat dissipation, which is why distance is actually important. The actual, physical size of the star is not as important as how much matter is burning inside of it, and the closer you are (so a smaller star that appears the same size means you are closer), the hotter it's going to be relative to you.
That's why everyone keeps mentioning distance. It's bloody important!
That's what I'm saying.
Double distance quater radiation..
Double radius quadruple radiation...
Double the radius AND double the distance...
No change (as one tends to infinity this gets more accurate because we are assuming a flat circle rather than a sphere).
Still more complicated - double the radius - 8 times the radiation because you're dealing with a volume of radiating core, not a surface.
OK, changing tack...
Go find one of those cool brown dwarfs (purple stars).
See how BIG THE STAR LOOKS (not how close) you have to be to get your temp up to 80. Approach slowly.
Try the same with a class O, B or A star.

You'll find that you can fill a lot more of the screen with a big star than you can with a Y or L before you start to overheat.
This is very odd, because the big star is MUCH hotter.
2 stars 1 HUD, is this hot?
Funny thing is, at the start of the thread I thought I knew what my opinion was on this, after 2 pages, not so much anymore.
Has anyone checked the sysmap for temps?

Nope.. common fallacy. Sorry, black body radiation is basically surface temperature (power four) and surface AREA dependant (directly proportional)... ignoring neutrino and sunspot radiation.
*remember* we're talking surface temperature here.

This thread is starting to make me think, and trying to remember stuff I learned long ago in ancient times. Lets get this on practical: What are the numbers on the stars, what are the mathematics, somebody got a calculator? Anybody here that can do some serious sience?
It's not the surface of the star that radiates the bulk of its energy, it's the core.
You're conflating two separate phenomenon: surface temperature and irradiation.
Take two stars with identical surface temperatures
The power being generated (energy lost) is proportional to the surface area of the star. That is all.
Double the power, double the surface area...
now, QUADRUPLE the power of the star and the surface area Quadruples, meaning double the radius
(For stars of the same surface temperature).
Sorry, please check your physics... The radiation generated at the core of the star is trapped, often for thousands of years. It's the surface layers that radiate. To all intents and purposes, a star is Opaque.

I prefer the T Tauri stars that fool people into trying to scoop from them as they "look" scoopable, evil little troll stars.
IKR... Have overheated a couple of times on those bugbears!
