Exempel på hur man kan använda HYPERGIANTS i en mening

• The constellation hosts some of the most luminous stars known, including the yellow hypergiants Rho Cassiopeiae and V509 Cassiopeiae and white hypergiant 6 Cassiopeiae.
• They are sometimes referred to as cool hypergiants in comparison with O- and B-type stars, and sometimes as warm hypergiants in comparison with red supergiants.
• The temperature intermediate between the red supergiants and yellow hypergiants has led to it being variously considered as a red hypergiant or yellow hypergiant.
• 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.
• Cepheus OB1 contains dozens of O and B class stars, but the brightest members are cool supergiants and hypergiants such as V509 Cassiopeiae (HR 8752) and RW Cephei.
