2M 1510 A circumbinary world in a triple brown dwarf system This addon isn't compatible with with any version of TTarrants' exoplanet catalogue before the May 2025 release. If you have a version before the May 2025 one you need to delete the 2M 1510 section in extrasolar.stc 2m1510-1.png 2m1510.png...

This addon adds 21 brown dwarfs which were picked up in the JADES and CEERS extragalactic surveys, conducted by JWST. (see https://arxiv.org/abs/2309.03250)

square = CEERS, triangle = JADES

This addon adds the CN15/16/17 complex, seemingly also called RCW 142. This complex, located almost 4,000 light years away in Sagittarius, has experienced at least two waves of star formation, evidenced by a population of B-type stars and another population of protostars, in the same place. cn151617...

OGLE-2017-BLG-1170L A tight pair of rogue Jupiters in the bulge This addon adds OGLE-2017-BLG-1170L, the lens in the microlensing event OGLE-2017-BLG-1170. Located deep inside the galactic bulge, the binary system consists of a 3.06 Jupiter-mass planet and a 1.85 Jupiter-mass planet orbiting each o...

what the hell is going on with the helix nebula planetary system man Yeah okay so uh a new paper at https://arxiv.org/abs/2412.07863 published in December suggested the existence of another planet... this time another superheated Jupiter-sized exoplanet. That paper ALSO mentioned the super-Earth pl...

haha oh well I guess these planets arent actually real haha

This addon adds the nebula NGC 1491, located almost 10,000 light years away in Perseus, as well as its central star, BD+50 886. Note: studies do say that this nebula is the result of BD+50 886 lighting up a background molecular cloud, aka a "Blister" nebula, given the lack of clear informa...

This addon adds the Dumbbell Nebula, a relatively nearby planetary nebula in Vulpecula. Thanks to Lux HMT for making most of the nebula model, once again.

the bell of the dumb

This addon adds RCW 36, a roughly bipolar star-forming region within the huge Vela C molecular cloud, located over 3,200 light years away and part of the Vela Molecular Ridge. RCW 36 is ionised by a central cluster with two O-type stars and a B-type star. Since RCW 36 and Vela C are closer to the ga...

This addon adds 20 star clusters discovered by the VVV survey and 89 of their constituent stars as described by https://www.aanda.org/articles/aa/full_html/2011/08/aa16662-11/aa16662-11.html

Some of them clusters

This addon adds the cluster Cl 1806-20, which contains LBV 1806-20 within it. Note that Cl 1806-20 can also be found in my DHMSA-CHIIR addon (https://celestiaproject.space/forum/viewtopic.php?p=155911#p155911), but that was from 3 years ago and since then my techniques have improved. You don't need ...

This addon adds two hypothetical planetary systems around fast radio burst (FRB) sources - SGR 1935+2154, in the Milky Way, surrounded by the supernova remnant SNR G057.2+0.8 (also in this addon), and FRB 180916, located in the small spiral galaxy SDSS J015800.28+654253.0, located almost 500 million...

yeah so turns out the planet isn't real, according to https://arxiv.org/abs/2409.06332 anyway, so here is the version without the planet

WD 2226-210 (Helix Nebula Central Star) A possible superheated mega-Earth inside our nearest planetary nebula? helixplanet.png Download: https://celestiaproject.space/forum/viewtopic.php?p=163360#p163360 (Be warned that this planet doesn't actually exist, according to https://arxiv.org/abs/2409.063...

This addon adds the nearby Helix Nebula, as well as its central star and its candidate superheated exoplanet. The nebula model itself was entirely done by Lux HMT , so thanks to him for that. Also credits to LukeCEL for the tail model and cubicApoc for the emissive model which I used for the planet ...

This addon adds 1,009 real stars in the small, irregular Local Group galaxy UGC 4879, located nearly 4.5 million light years away in Ursa Major.

This addon adds 72 real stars in the Sagittarius Dwarf Irregular Galaxy viewtopic.php?p=163186#p163186

This addon adds 72 real stars in the Sagittarius Dwarf Irregular Galaxy, consisting of 17 carbon stars, 45 red giants, 1 very weird AGB star, and some massive young stars, including a G-type red supergiant. There is comparatively little information on the stellar population of this tiny galaxy in ge...

Re-uploaded the CHSS stars file since I noticed a problem with the declinations listed

PSR J1555-2908
A Mercury-mass world orbiting a black widow system containing a millisecond pulsar

The planet
