Classification[edit]

Y CVn (La Superbathis) is too faint to call a red supergiant. The luminosity of Y CVn is 4,400 times solar. Meanwhile that of Mira is 8,400 times solar. Y CVn is less luminous than Mira. Mira is a M7III type normal red giant. Therefore , Y CVn should be a normal red giant.

The classification "I" in the spectral type "C7I" of Y CVn means "Most luminous class of carbon stars". But this class is too faint to call red supergaint's class.

Reference information : List of M type giant stars.

1 Most luminous supergiant(hypergiant)

  • VY Canis Majoris The luminosity is 400,000-500,000 times solar and the mass is 30-40 times solar.

2 Luminous supergiant(Ia type).

  • Mu Cephei: The luminosity is 250,000-350,000 times solar and the mass is 25 times solar.

3 Faint supergiants(Ib type).

  • Antares: The Luminosity is 65,000 times solar and the mass is 15 times solar .
  • betelgeuse: The luminosity is 63,000 times solar and the mass is 14 times solar.

4 Bright giant(II type).

  • Alpha Herculis: The luminosity is 20,000 times solar and the mass is 7-10 times solar.

5 Normal giant(III type).

  • Mira: The luminosity is 8,400 times solar luminosity and the initial mass is about 2 times solar.
