Supergiants are rare and short-lived stars, but their high luminosity means that there are many naked-eye examples, including some of the brightest stars in the sky. Rigel, the brightest star in the constellation Orion is a typical blue-white supergiant; Deneb is the brightest star in Cygnus...
that they stand out in external galaxies. There is an upper limit to the absolute bolometric magnitude of cool red supergiants (–9.7), so the brightest supergiants can be used as approximate distance indicators. Examples of supergiant stars are Rigel and Betelgeuse in Orion, Antares in Scorpiu...
Red Supergiant Examples Lesson Summary Frequently Asked Questions Are red supergiants the hottest stars? No, red supergiant stars are not the hottest stars. They are some of the relatively coldest stars that exist in the universe. What is an example of a red supergiant? The star named Betelge...

Red supergiants are rare stars, but they are visible at great distance and are often variable so there are a number of well-known naked-eye examples: Psi1 Aurigae CE Tauri Antares Epsilon Pegasi Betelgeuse Lambda Velorum Mu Cephei Other examples have become known on account of their enormous...
The supergiants are among the best examples of this class of variable, perhaps the best known being the M supergiant Betelguese (α Orionis). In many ways, these stars resemble the RV Tau and Mira variables, but without the regularity of variability associated with these other stars. The ...

(VFTS 744), which is likely a semi-regular variable asymptotic giant branch star. Calculations of semi-amplitude velocities for a range of RSGs in model binary systems and literature examples of binary RSGs were used to guide our RV variability criteria. We estimate an upper limit on the ...
