However, because the stars are both very luminous and have very distinctive spectral features, it is possible to identify these stars in the spectra of entire galaxies and doing so allows good constraints to be placed on the properties of the starbursts in these galaxies.
Porén, como as estrelas son moi luminosas e teñen características espectrais moi distintivas; é posible identificar estas estrelas no espectro de galaxias enteiras e facelo permite que se establezan boas restricións sobre as propiedades dos starbursts nestas galaxias.
