A2 Iae is a designation used in the field of astronomy, specifically referring to a type of star. It is classified within the A-type stars, which are known for their blue-white color and high temperatures. These stars typically have a surface temperature ranging from 7,500 to 10,000 Kelvin and are often found in the main sequence phase of their lifecycle. The "Iae" part of the designation indicates that the star is a supergiant, which is a massive star that has expanded and cooled after exhausting the hydrogen in its core. Supergiants like A2 Iae are among the largest and most luminous stars in the universe, often outshining their smaller counterparts significantly.
