VY Canis Majoris and WOH G 64

Post #1by Eric Nelson » 01.12.2023, 03:33

After studies shown that VY Canis Majoris and WOH G 64 are enshrouded by dust clouds and reasonably-defined properties, I worked on addons for VY Canis Majoris and WOH G 64 with the help of SpaceStalker's Stephenson 2-18 addon, via here; https://celestia.mobi/resources/item?item=6E8719CA-3216-46C0-8478-CB7F81FC0B49 so I give him credit as well.

Unlike Stephenson 2-18, which was calculated by several different methods with poor certainty and reliability, VY Canis Majoris and WOH G 64 were calculated from methods with apparently better certainty and reliability.

VY Canis Majoris is approx 3,820 light years from Sol currently said to around 1,420 +/- 120 x Sol's radius and has a surface temperature around 3,490 K.
WOH G 64 is approx 163,000 light years from Sol and is currently said to be around 1,540 +/- 77 x Sol's radius and has a surface temperature around 3,008 K.
Therefore VY Canis Majoris is virtually the largest well-calculated known star in the Milky Way (and perhaps anywhere).
WOH G 64 may be farther away, but has better certainty than stars like NML Cygni, UY Scuti or Stephenson 2-18 (due to the better analysis despite various techniques to detect all these stars), and is virtually so far the largest star we found in the Large Magellenic Cloud (and perhaps anywhere as well, competing with VY Canis Majoris, especially when accounting for the caveats and margins of errors along with the asymmetry for each star - as modeled in these addons).

The textures for the stars were slightly tweaked in brightness and colors to match the spectral types (as VY Canis Majoris is a M65eIa+ red hypergiant and WOH G 64 is a M7.5e red supergiant), and the radii for the dust clouds and disk were moderately tweaked in respect to the radii of these stars.
