estrela hipergigante
Sign in to saveAlso known as hypergiant star
A hypergiant (luminosity class 0, Ia-0 or Ia+) is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds. The term hypergiant is defined as luminosity class 0 (zero) in the MKK system. However, this is rarely seen in literature or in published spectral classifications, except for specific well-defined groups such as the yellow hypergiants, RSG (red supergiants), or blue B(e) supergiants with emission spectra. More commonly, hypergiants are classed as Ia-0 or Ia+, but red supergiants are rarely assigned these spectral classi

Estrelas hipergigantes (luminosidade classe 0) são estrelas que possuem pelo menos 50 massas solares e luminosidade acima de 1 milhão de vezes àquela emitida pela estrela do Sistema Solar. Elas também podem ser categorizadas pela força gravitacional e pela influencia orbital que esse tipo de estrela tem.
