HD 113538

HD 113538 is a yellow giant star located approximately 340 light-years away in the constellation Centaurus. It is a relatively bright star, visible to the naked eye under good viewing conditions.

HD 113538 has a spectral type of G8III, indicating that it is a giant star that is cooler and less massive than the Sun. The 'G' designation signifies its yellowish color, and the 'III' indicates its luminosity class, meaning it is a giant star. Its surface temperature is estimated to be around 5,000 Kelvin.

This star is considerably larger than the Sun, with a radius about 10 times greater. It is also much more luminous, radiating approximately 50 times more energy than our Sun.

HD 113538 is believed to be in a later stage of stellar evolution, having exhausted the hydrogen fuel in its core and begun fusing helium. It is moving towards becoming a red giant before eventually shedding its outer layers to form a planetary nebula, leaving behind a white dwarf remnant.

The designation "HD" refers to the Henry Draper Catalogue, a comprehensive astronomical catalog that provides spectral classifications for a large number of stars.
