Here's exploration data of over 1,000 stars

I originally made this post over at /r/EliteDangerous and /r/EliteExplorers, but I might as well post here now that I'm going to try be more active on the forums (outside the bug report section). Here's what I wrote:

TL;DR: I documented Wolf-Rayets, White Dwarves, Neutron stars and Black holes in a spreadsheet, I also took screenshots of them all here (zip). The TOV limit is between 2.5117 and 2.5156 solar masses. The only factor for a star's value is its solar mass.

So mid-trip I decided to document as many Wolf-Rayets as I could for the fun of it. After about 100 entries I switched to non-sequence and White Dwarves.

From my data I ended up earning 98,081,463 Credits from my journey, enough to reach Pioneer, but I had my hopes I would get enough for Elite. Maybe next time!

In my spreadsheet I created over at Google Docs I've documented the age, type, solar mass and solar radius of the most valuable types of stars. I did also document how much each star was worth and put up some graphs to get a better feeling for what the data represents.

When it comes to neutron stars I was quite baffled of what I found. This might be something that is explained in science but it is not something I've encountered before. The solar mass increases in variance after the solar mass increases above 0.85 solar masses or thereabouts. As seen in the graph below, there is a distinct increase in variance. The variance below 0.85 solar masses equals to 0.0110 variance and represents 58.40% of all data, and above 0.85 solar masses there is 0.1984 variance representing 41.60% of all data.

Continuing on with neutron stars I had my hopes on figuring out the highest mass a neutron star can be, in hopes to pinpoint the TOV limit in the game, and the highest solar mass I found was 2.5117, which is quite huge! Furthermore, the highest and lowest temperature of the neutron stars I've found is 9,996,562 and 941,981 Kelvin and I have my doubts there are neutron stars above 10 million Kelvin in the game.

Wolf-Rayets, although not worth much, were the most fascinating for me. The fact that there were some Wolf-Rayets far colder than the average Wolf-Rayet, made me confused at times (found one at 2 Kelvin!). I also documented every type of Wolf-Rayet there was, including which one is the most popular, as seen in the graph here:

Furthermore I noticed that the solar radius stayed roughly the same for all Wolf-Rayets in comparison to the solar mass, as seen in the image below. Last but not least the credits earned from the Wolf-Rayets increase at a slower rate than the solar masses increase.

White Dwarves (Dwarfs?) wasn't documented that much and should probably be taken with a bit of salt. They are worth around 22,624 Credits on average, the most common type is DC and the rarest I found was DBV as seen on the graph below. The solar radius stays roughly the same even though the solar mass increases, much like how Wolf-Rayets do.

Last but not least, black holes. Probably the part I wish I'd documented more on as it would probably show us in greater detail where the TOV limit is and how much they're worth on average. The credits earned for each black hole follow the same incrementation as the solar mass.

Oh and I also documented a few terraformables, but it's nothing major.

I'd love to see people come up with algorithms and various other scientific explanations from my data.

And that's pretty much it, here is a template I made and here's a few screenshots I took from my trip, shout-out to CMDR FatHaggard!

Nice work CMDR
Dare I even ask how long this survey took? I know there's a few commanders on the forum that will be pouring over your findings, you might want to report that terraformable information to Jackie Silver who's been working on the stats for terraforming candidates, they might need the extra data.
Ill have to check out /r/EliteExplorers if there's this much science going on over there. +rep, welcome to the explorer forum.

Thank you!
It took a few days more than a month, but I only started collecting data mid-trip! I'll send him a message about it. Oh and /r/EliteExplorers is mostly filled with nice screenshots, questions and updates, but there's also threads about scientific data
 
That's excellent data you share with us here. Really enjoy those figures, although I am not a mathematician. What has baffled me before and still does after reading your graphs is that the procedural star generating thing in ED tends to ignore some atrophysical theories that are current in our 20th/21th century scientific community. For example, Neutron Stars ought to have at least 1.1 Solar Masses, else they would be White Dwarfs. It's called the 'Chandrasekar Value' I think. Same with Black Holes: They are believed to form upwards from 3 Solar Masses if I remember correctly, whereas I've seen Holes having less than two Solar Masses.

I would love to see a graph on T Tauri stars as well, maybe I'll go collecting some data myself in 'Tauri-Land'.

Once again, thanks! Fly safe!

Yes, the Neutron stars and White-Dwarfs seem to be missed out on as the Chandrasekhar limit seems to be missing, but with black holes I'd imagine that the TOV limit is just as documented, between 2.5117 (highest neutron star mass) and 2.5156 (lowest black hole mass) solar masses.

Protostars was one of the things I didn't look at that much, maybe I'll do so for my next trip! :)
 
Phenomenal work!
You've set the bar very high with this standard of analysis! You've given me something to consider with my own set of data when I get around to looking at it more closely.
I'm keeping basic info in my spreadsheet mainly for tracking the value of interesting worlds. I can go back over the neutron stars and black holes in my systems list, look them up on galaxy map and get the info to help extend your dataset.
That will have to wait a while though. I need to see about getting the data sold first.

Thank you and sure thing! If you want to add how much they're worth as well you'd probably have to spend at least 4 days documenting it (as I did). The document is protected to avoid vandalism though, but I can add you to it if you want to add data (requires gmail and it will show up in the top right for others to see when editing)
