Notes
Menkar (alfa Cet) has evolved from the main sequence after exhausting the hydrogen at its core. It has also exhausted its core helium, becoming an asymptotic giant branch star, and will probably become a highly unstable star like Mira before finally shedding its outer layers and forming a planetary nebula, leaving a relatively large white dwarf remnant.[19] It has been observed to periodically vary in brightness, but only with an amplitude of about one hundredth of a magnitude.
