This small addon adds 3 late thermal pulse stars, stars which have passed the AGB stage and are going through a small flash of fusion before they actually die. About a quarter of all AGB stars go through this phase.

The 3 stars (Sakurai's Object, FG Sagittae and V605 Aquillae) are all quite different from each other in terms of parameters.

This is my 4th version of the galactic WR stars addon. I think it adds WR 20, 24, 35, 39, 52, 60, 61, 62, 67, 77f, 77n A, 77n B, 82, 87, 89, 90, 94, 100, 101-2, 102c, 105, 111, 111-13, 120, 133 A, 133 B, 134, 135, 138a, and 142a.

This addon adds HD 45166, an exotic binary system containing a B-type star and what is called a quasi-WR star, an object whose spectrum resembles that of a WR star, but is formed differently and is less massive. HD 45166 A is an extremely rare example, and was likely formed from the collision of two helium stars. HD 45166 A is also extremely magnetic, and so when it ends its life with a supernova, it will produce a magnetar.

This addon adds NGC 2020, a large WR wind-blown bubble nebula in the Large Magellanic Cloud, and its central star, the Wolf-Rayet binary BAT99-59. I've wanted to make this for a long time.

Distant, hidden massive stars, clusters and H II regions (or DHMSA-CHIIR) is a big addon that I have been working on for the last 5 months (with a bit of help from Gurren Lagann and The Minmus Derp), which adds a lot of star clusters and H II regions, as well as many massive stars in the Milky Way.

You can find the addon here: viewtopic.php?f=23&t=21739
I moved it to its own topic because I think it is deserving of its own, given how big of an addon it is.

This small addon adds the Frosty Leo Nebula, a protoplanetary nebula housing a K-type giant star about 10,000 light years away in the constellation of Leo.

A small addon containing a lot of random stars. Note that some of the stars' parameters are assumptions and/or guesses, such as V5630 Sgr's temperature.

This addon adds the distant starburst cluster VDBH 222, which contains a rare yellow hypergiant.

This cluster actually exists ingame (it's called BH 222), but since it's normally called VDBH 222, I decided to make a separate cluster, also because BH 222's distance to the solar system is outdated. This doesn't contain all the stars in the cluster though, because I gotta be honest with you, I can't be bothered to add like 50 B-type stars from a VizieR table atm. I'm really excited for the next addon I'm going to make, and maybe I'll come back to this in the future.

This addon adds 4 massive stars to the Sagittarius Dwarf Irregular galaxy. And no, the G-type star is not a yellow supergiant, it's a red supergiant. That is because the super low metallicity makes red supergiants much hotter, and in the Sag DIG, the metallicity is so low that red supergiants become G-type.
