Guide to star types?

[Electric Donkey]

Finally got around to making some warpers and wondering which star I should visit first. There's no steam guide, neither of the two DSP wikis has an article on stars, and although I know I've seen threads here about this, I can't find them with steam's sad search feature (no option to limit to thread titles).

I'm not 100% sure if the star type has any exact affects on resources but I know Unipolar magnets are new blackholes. If you have universe exploration level 4, you can scout out star systems and it'll let you know what resources are in them but you won't be able to look at planets directly until you're in the system.

Neutron Stars and Black Holes

Still too early for me to confirm, but if it's based on real life in any significant way than certain types of planets will only spawn around certain types of starts. Mediterranean planets in particular, the type the Starting Planet (moon) is, in particular should only be spawning around G type stars, like our sun.

With regards to Dyson Spheres specifically, O type stars as a group tend to be capable of supporting better Dyson Spheres, for 2 reasons. First, they tend to be the biggest stars, which in turns allows you to build a larger radius Sphere around them, which increases the energy you are able to derive from it. Second, they tend to have a higher Luminosity rating, which acts as a multiplier on the energy that can be collected by any Sphere built around it.

This, in turn, would mean that a Super Giant O type star would likely have the highest energy output possible from a Sphere built around it.

The stars are classified and made up as they are in real life.
We have overall a simple classification of stars. They are primarily aranged by surface temperature. Other weightingfactors are Mass, Fusionmaterial and Luminosity (How much Light a source is radiating at a given time)

As an overview just the 7 classes with their average surface temperature range in Kelvin and for Fusion they use Hydrogen to Helium

O >25k K - Bright blue
B 11k - 25k K
A 7,5k - 11k K
F 6k - 7,5k K - Blue White
G 5k - 6k K - Blue Yellow (our Sun)
K 3,5k - 5k K
M <3,5k K - Dark red

And then you have specialities like Neutron Stars and Pulsars.
Neutron stars are usually collapsed Blue Gigants, mostly composed of Neutrons. They yield massive energy (mostly conservated in Neutrons) and radiate it but they dont have an active Fusion anymore.
Pulsars are usually very magnetic Neutron stars (but also White Dwarfes are possible) which emit radiation at their poles so they theoretically look like a star core with beams from their poles pulsing.

For energy usage thechnically a Neutron star is the best because it radiates so much in every direction. But this radiation is so strong, it would fry everything in its vicinity.

So we are left with the mayjor seven classes of stars.
O is the best for energy, M is the worst.
You can even see that by their color. Infrared is the least energetic radiation and UV the most energetic radiation. (The color spectrum goes from darkish red to dark blue/blueish purple, keep it as a bridge)

Arranged on this you have the plantes. For organic ligfe as we know it, you need a habitable zone around a star. So it cannot be that energetic, nor can you be in such a great distance that the Day/Night Cycle takes too long. Therefore Gs and lower class Fs are optimal. (Doesnt mean they canot be found somewhere else)

Mineral rich or barren and frozen worlds are common everywhere except maybe around a Neutron or some Big Os. Gas Gigants or Frozen Gases can also be found everywhere.

For expansion I would expand to the nearest ones first. Doesnt matter what type of star it is. Important is if they yield rare resources (or even Sulfuric Acid oceans) or not.
If I can support another DS before I need even more expansion, I would go by star class first and then look at the systems yield and would try to find a compromise.

Except those are really rare (if they exist), as rare as unicorn even. I have seen none, and I did a lot of restarts when trying to get a good giant as close to start as possible so I could fly there without warp.

You usually get Red Giants (K type) or Blue Giants (B type). Rarely a White Giant (A) or a Orange/Yellow (F/G) but those are more rare than red and blue. Granted, a giant usually has about 10-15% higher luminosity than a star of equal type and the Blue ones are especially hard to tell from the map alone, you get the whiter and the bluer variant, but the white one is about L2 while the blue one is about 2.3, those numbers being quite a bit higher than the normal stars of their types and especially the blue one being almost on par with the worst of normal O types. The game still shows it as B and I guess that is right.

Even though blue ones are best for energy I bet most players do not particulary enjoy playing near them, they are freaking crazy bright when you are too close to the point of you not being able to see anything and blue hue is not as comfortable to look at as red or yellow.

The important stars are Class O which are the optimal stars to build a Dyson Sphere.

And I am still waiting on a second opinion but no one else has confirmed it with me: Systems prefixed with the Eta symbol 'η' which is what I am still trying to get a peer review means that it supports many planets.

These in addition to the Blackholes and Neutron stars.

Distance to home star appears to factor resource count.

For the other stars, I haven't found much in terms of unique resource factors as have found all resources on all combinations of star type with the exception of unipolar magnets.

When you just get warpers, your initial expansions will be to get access to useful resources - typically Sulphuric Acid and Organic Crystals because they're a pain to produce using the standard recipes. Fire Ice may be on the wishlist too if you don't have an ice giant.

I recommend initially to expand to yellow and red stars. They have a much lower mass, which makes their planets orbits more narrow. This allows you to use the planets as a single resource pool by using logicstics vessels without warpers between them, much like in your starter system. Heavier stars, A class and up, tend to have planets with huge orbits that make warper-less transports between them less efficient.

Once you are ready to start establishing your first serious Dyson Sphere, find an O class star with a planet that is inside the outer orbit of the Dyson Sphere. You'll be able to have the Ray Receivers always on on such planets, wherever you put them - and O class stars are very efficient in terms of rocket-for-power. Each rocket you send is 100kw * luminosity of power produced, and the huge shell radius around O type stars means you can fit an insane amount in them.

As you expand further you'll want to scan each system for rare resources - those seriously reduce the amount of basic resources you need, making your factory much more efficient. Use the alternate recipes wherever you are able, they matter, and if you invest a little in vein efficiency, you'll rarely run out ('though given its rarity, you may want to economize on unipolar magnets initially).

As other have said, Neutron Stars and Black Holes have Unipolar Magnets, but also White Dwarves have guaranteed rares as well on one of it's planets and it's guaranteed to have at least one. Specifically Optical Grating Crystals, Fractal Silicon, and Kimberlite Ore.

Other good mentions are F, B, and O type stars. O types are young, and are good types for Dyson Spheres, often have many planets and lots of resources. B are middle life and have well developed planets, are decent candidates for Dyson Spheres, and as far as I've seen have a higher likelihood for rarer resources. F types also have a chance for a larger amount of planets.

K types, A types, and M types are generally lackluster stars in general from what I've seen, as well as giant types. You could get lucky with them, but if you have a choice, go for the others first.
