Trying to understtand how Stellar forge determines star mass

Col Frost · May 21, 2017

I recently searched a sub sector of D mass stars for ELW's and came across some strange results.

When searching D mass stars (XXXXX-XX-X DXX-X, with D indicating the overall mass of the system) I usually come across mostly F,G,A, sometimes K and very rarely Neutron stars in a given sequence.

In this particular sub sector of just 28 D mass stars (flyua dryoae so-g d11-0/28) I found the following star class distibution:

F class: 14
G class: 7
K class: 2
M class: 4
L class: 1
T class: 1

In a sub sector of just under 10,000 stars D mass stars I searched near the core (zunou gs-b d13-0/9880) I never found any M, L or T class stars.

The coordinates of the first star in the sequence are: X= 2356.28, Y= 520.56, Z= 96.00.

I find these star classes very strange and wonder what stellar forge is up to here.

Anyone have any thoughts on this?

I think that's inside the corridor of suppression that runs north-south and also east-west from Sol. It's partly to do with real hand-authored stars replacing the proc-gen ones, but there's more to it than that; the corridors extend right to the edge of the galaxy.

Someone did a map recently that had all the known neutron stars plotted on it - you can see the corridor very clearly on that because it wipes out neutron stars too so there's a massive line up the map that's devoid of neutrons.

(Not the one I was thinking of, but you can see it here.) -set the map to 2d and zoom out a fair way.

Anyhoo, point being that your sector is inside that particular weirdness, whereas the one you looked at near the Core is normal and working as expected. Go Forge!

Amazing info, thanks Jackie

That is very interesting. Any ideas on why it is so? Why do these corridors reach to the edge of the galaxy? FD won't have manually edited all the Systems 'til there, would they?

Here you go, including a link to the thread with the rest of the maps:

Redfox are the maps the labelled correctly? I believe the one showing the Neutron stars might be for ELW's instead.

CORRECTION, I think your labelling is good, even 500 ELW's in such a small area would only be a dot anyway

The reason I say this is that Chiggy and me found over 500 ELW's near the core in adjacent sub sectors and this seems to show up on the Neutron map, but not the ELW map.

Here's the area we searched form my perspective

and zoomed out a bit

and a bit more to give location

I think Jackie is correct. If you continue straight north from that point, near the Sag A you will find weird sectors with thousands of AA-A systems. All of them are totally regular and boring M, K and even T and Y class. To add to the weirdness, there are no O, B and A class stars there, despite being in the heart of the Core.

Perhaps a good place to look for the most massive stars of all types for the record books?

No, not at all. All these AA-As are "fake", to say so. For most massive objects you need the "real" AA-As. Those with WRs, Blue Supergiants and Herbigs. These can be found further east and west from Sag A - Bubble line. They are abundant in the Core area

In your screen shots though...D code stars with .16 and .10 solar masses so in these fake areas, the code doesn't seem to correlate with the actual mass, so the normal rules just don't apply. The dwarf's above may have D codes, but their actual mass is inline with the star type.
