Neutron star luminosity

I've noticed that the hotter the neutron star the dimmer it gets. This should be the other way around. (actually this might be due to them emitting more in the X ray wavelength than in visible)

Planet atmospheres

How are the atmospheric pressures calculated? Because I've found 0.1 Earth mass terras with atmospheres over 100 times thicker and 100 K hotter than Earth. That should be impossible and a 9 em planet will most likely be a gas dwarf and if it's not its atmosphere would be over 80 times thicker than Earths. (A lot of 9 Em terras have 0.05 atm press) (note i only account for pressure in habitable zone)

P.s. I think spaceway has a good atmosphere function and same with stargen

P.s.s. Can this thread be move to troubleshooting and solutions please smile

Multiple star systems

I've notice that in alot of cases in multiple star systems (three or more) the orbits of the stars dont match where the mass should be. In the example i have the more massive barrycenter (6.6 Sol mass) is orbiting and barely wobbeling the less massive (4.3 Sol mass) barrycenter. Then a brown dwarf orbits these two masses (10.9 sol mass combined) and swings them around considerably even though its only 0.08 sol masses. So it seems than only the brightest stars mass is taken into account when calculating the orbits of stars in multiple systems. (ignoring the dimmer ones though)



Example system: RS 10368-425-9-91748725-454 A

Okaaay... surprised

Could someone please explain me how to get these kind of stellar graphics?
They look pretty awesome biggrin

n3xt, the one you're looking you'll find it here : http://en.spaceengine.org/forum/17-730-1

you can also find another "lens flare" and other addons for the game under the section "Mods and Addons"

Okay thank you I got it, however I have a weird buggy problem at the moment I'm trying to resolve.

Okay i've noticed that supernova remnants are extremely dim around 5 sol luminosity. I think theyed be on average 1500x brighter than sol. So i have bumped up their luminosity and was satisfied with the results.

Change the code in the univerese confige to match this.

Code
NebulaSNRLum            1500.0  // SNR nebulae mean luminosity
NebulaSNRLumDisp        1500.0  // SNR nebulae luminosity dispersion
