Strange stars and their stats.

[Prorokpl]

So I found bunch of O type stars next to each other and they are strange. Or the stats are incorrect and Frontier has to change them or the stars are just strange.

So first one is very very old star that should be gone by now. Here's an example where life-span should be 1-10 milions of years but star is 90x times that age. So why it didn't went Supernova by now?

Spoiler

There is also HUGE F type star which is not consired as Supergiant or Giant star. But look on the size of that thing.

Spoiler

As a bonus to that there is a Amonia world with large pressure over 10 tousand!!!!1!! *Vegeta screams*

a. as for 1, - maybe it evolved into an o-class "recently"? not sure whether that is possible, though

b. as for 2. size isn't what makes a supergiant, but absolute visual magnitudes (and temperature). what does the galaxy map say about its luminousity?

c. nice find

As for b. how can I check that?

in the galaxy map, here:

supergiants have a luminosity of I:

In response to b, FD have some weird classifications sometimes. For example, I've found about 3 'red giants' before, yet they were smaller and less massive than the Sun

That doesn't help for this system because the galaxy map only lists the main objects orbit a common barycentre. The F type star from your other screenshot is orbiting another star so it doesn't get listed in the galaxy map.
But I agree that this star should probably be considered a giant at least because I doubt it's not luminous enough with that size and temperature.

Regarding the O-type star you are correct, it shouldn't say 910 million years as this is pretty much impossible. O-type stars only live for a few million years before they either end as a supernova and become a black hole/neutron star or they continue as a B-sequence giant. There is no way it could be almost a billion years old and still be in O sequence.

The ammonia world is interesting. It's probably due to the 44 earth masses which causes the atmosphere to have such a pressure. Plus the atmosphere will probably be many many times as dense as ours. It all ads up to such a high pressure.

This is not entirely true. The galaxy map only shows primary stars until you visit the system and honk. After you have done this, the galaxy map lists all nested stars. So in this example the F is listed here: F5 IVA. In other words it is an F-class Subgiant.

Actually you are correct, my bad.

Today I found a young star, a VERY young star. The stats say 00,0 MY. Thus we can assume this baby is younger than 100.000 years.
It has a nice purple tough to his color.
