IK Pegasi BHaving a surface tempeture of 35,500 kelvin (63,440.33 degrees f ) the image at left shows IK Pegasi B and it's size relationship between its A-class companion IK Pegasi A (left) and the Sun (right) and may also help illustrate why the white dwarf can sometimes prove to be a hard star to locate. IK Pegasi A is currently considered a main sequence star that is right on the edge due to it's placement on H-R chart known as the instability strip. Stars in this band oscillate in a coherent manner, resulting in periodic pulsations in the star's luminosity. Source Reference: ESO Report...IK Pegasi (HR 8210) and IK Pegasi from Wikipedia.
