[DBS2003] 75 and ESO 95-1

Post #41by Trolligi 112477 » 27.03.2022, 18:49

This small addon adds the small, young cluster [DBS2003] 75, along with the compact H II region in it, ESO 95-1, located 18,300 light years away in the constellation of Crux.

Scutum X-1

Post #42by Trolligi 112477 » 31.03.2022, 12:56

This small addon adds the intermediate mass X-ray binary Scutum X-1. It is composed of a neutron star sucking material away from a luminous Mira variable.

Gas-rich ultra faint dwarfs

Post #45by Trolligi 112477 » 02.05.2022, 20:22

This small addon adds 5 gas-rich ultra-faint dwarf galaxies to the Local Group. The paper for all this is https://arxiv.org/abs/1908.00438.

BM Cassiopeiae

Post #46by Trolligi 112477 » 28.05.2022, 14:42

This small addon adds the binary star BM Cassiopeiae, one of the weirdest eclipsing binaries I'm aware of. It contains an """""A-type""""" supergiant orbited by a """""G-type""""" supergiant with about half its mass, every 200 days, located almost 12,000 light years away in the constellation of Cassiopeia.

Serpens-Aquila Rift Star-Forming Regions

Post #47by Trolligi 112477 » 22.06.2022, 21:24

This addon adds several star-forming regions in the Serpens-Aquila Rift, all about 1400 light years from the Sun, which include:
    Westerhout 40
    Serpens South
    Serpens Main (and the clusters within it, SVS 2 and SVS 4)
    MWC 297 Asociation
    Serpens NH3
(as well as a background post-AGB star)

I made this addon because I think everything here is quite underrated, and it shouldn't be given how close it is to us.

A lot of the areas are quite underpopulated (most notably Serpens South), so I may expand on this in the future. I will edit the post if I update it, and there is a changelog at the bottom.
Also a lot of the stars in this addon are very dim so you will need to either use celestial browser or look in the code.

Leo P addon (New, Aug 2023)

Post #49by Trolligi 112477 » 17.07.2022, 17:57

This ever-redone addon adds the Leo P galaxy, a small irregular star-forming galaxy located about 5.3 million light years in Leo. Leo P is part of the Antlia-Sextans group of galaxies.

Thanks to Gurren for most of the work making all the stars.

Latest version Aug 2023

WR Impostors

Post #50by Trolligi 112477 » 22.07.2022, 18:11

This addon has been waiting for 7 months, now it's finally out. It adds many stars which were thought to be Wolf-Rayets but in reality were not. Bonus: They are textured! Thanks to Gurren for the textures.

KSw fast rotators

Post #51by Trolligi 112477 » 29.07.2022, 16:39

I made the fast rotating stars from the KSw survey, known as pumpkin stars. And well... they really aren't. Revised paramaters have shown them to be much smaller than previously thought which makes them really not oblate.

Even the most oblate of them, KSw 71, shown here, is only slightly oblate. It's not a "pumpkin star" at all and neither are any of the others, all of which are almost completely spherical.

GA-MSCHIIR

Post #53by Trolligi 112477 » 06.08.2022, 21:26

GA-MSCHIIR (Galactic Anticentre Massive Stars, Clusters and H II regions) is a small project that is similar to DHMSA-CHIIR, except that it's on the other side of the galaxy. I will add more stuff as time goes on.

Stuff:

The S235 Complex, a star forming region centered on the nebula Sh 2-235 and nearby nebulae. There are many massive stars here.

IPHASX J052708.2+383113, a tiny 2 ly wide reflection nebula which surrounds a tiny cluster, of which only 1 star, an intermediate-mass protostar (I'm assuming), is on simbad. No image required since it's literally a star encased by a shell (the closest I can get to what it actually looks like, probably).

The CB54 molecular cloud, a small and distant molecular cloud in Canis Major, containing two main young stars. Two other stars also illuminate reflection nebulae around the molecular cloud. (There's actually a southern molecular cloud but since it's completely starless I decided not to add it)

SNR G353.6-0.7

Post #54by Trolligi 112477 » 20.08.2022, 22:26

This addon adds SNR G353.6-0.7, a supernova remnant containing what remains of an ancient binary system of an aging, now-dying red giant and an accreting neutron star. Now the old red giant is shedding its outer layers and turning into a planetary nebula via a hot post-AGB star.

Ou Planetary Nebulae

Post #59by Trolligi 112477 » 29.09.2022, 10:36

This addon adds two planetary nebulae from the "Ou" series, of which there are 6 in total. However two of the six (Ou 1 and Ou 4) are not PNe and for another two I could not find enough information to make it and its central star in Celestia.

So this addon adds Ou 2 and Ou 5. Ou 5 is noteworthy as it is a post-RGB nebula, not a post-AGB one, meanwhile Ou 2 is a pretty regular planetary nebula.

Also for Ou 5 I guessed the colour. I could not find its true colour anywhere. I also guessed the temperature for Ou 2's central star, based on the D0 spectral type temperature. I used several relations to work out its parameters as I did not have a v-band magnitude value, only a G-band one.

Ou 2 (left) and Ou 5 (right) to scale, and oriented in the way they would be seen from Earth
