As an expert in astrophysics, I can tell you that the concept of the "hottest star" can be a bit complex, as it depends on how we define "hot." In astronomy, the temperature of a star is often measured in Kelvins, and the hottest stars can reach temperatures of over 40,000 Kelvins. However, the hottest known star is not a main sequence star but rather a type of star nearing the end of its life cycle, known as a Wolf-Rayet star. These stars are extremely hot and luminous, with temperatures that can exceed 200,000 Kelvins.
Wolf-Rayet stars are typically found after a massive star has shed its outer layers and is left with a very hot core. One of the hottest stars known is the Wolf-Rayet star WR 102ka, which has been measured to have a temperature of over 200,000 Kelvins. It's important to note that the universe is vast and constantly evolving, so new discoveries may reveal even hotter stars in the future.

Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it's the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
