Here you can help me find large stars (over ~1500 solar radii), you can give sizes and refs here, or on my discord server at https://discord.gg/8r5Csca
List of suggested stars and their sizes
edit| Star name | Solar radii (Sun = 1) |
Source | Suggested by: | Status: |
|---|---|---|---|---|
| Dark star (dark matter)s | 2-1,000 Au (~400-~3,500 solar radii) | PNSMurthy | 
| |
| Quasi-stars | 7,187 | PNSMurthy | Still finding source
| |
| Red Supergiants in the early Universe | ~5,000 | [1] | Nussun05 |  Verified.
|
| THA 34-26 | 2,752.67 | [2] | Nussun05 | Verified but probably unreliable. Derived from TESS data.
|
| Unknown ~M9Ia+ red supergiant star exceeding the Humphreys-Davidson limit | Possibly 2,520 – 2,600 | Unknown; seen on a post by Sam Halls at Quora | SpaceImplorerExplorerImplorer | There is probably a source that was not mentioned on the post.
|
| V1804 Sagittarii | 2,050 | Unknown; seen on a post by Sam Halls at Quora. Another paper has a calculated radius of 682 R☉ assuming the Gaia DR3 distance. | Nussun05 | No source yet. Another reference has a calculated radius of ~682 solar radii assuming the Gaia DR3 distance.
