What is the hottest star in your universe?
it's the blue hypergiants, like Eta Carinae and R136a1, which are probably the hottest stars in the Universe. These are estimated to be around 40,000 degrees Kelvin.

Thanks for the feedback!
blue stars are the hottes star out here and then white and so on
Greyson chance and Taylor lautner everybody knows that!
The hottest thing that exists in the universe is not a quasar (super-luminous sources in distant massive galaxies), simply because a quasar is not giving off immense heat …but a massive amount of radiation and light energy. The hottest thing is actually, believe or not, conceived right here on Earth. It is in the LHC (Large Hadron Collider) an instrument that smashes atoms and protons into each other at relativistic (near-light) speeds to create very high-mass particles. The energy is so great, that the temperature for a split second is approximately 10 million billion degrees Celsius. See link for reference. This is the hottest known place and thing that exists to humanity as far as we now know. --- The interior temperature of a newly-formed neutron star is believed to be the hottest for naturally-occurring processes, as much as 100 billion degrees Celsius. Of course, vastly higher temperatures would have existed in the immediate aftermath of the Big Bang. The hottest possible theoretical temperature is called the Planck Temperature, which is 10^32 kelvins (100 million trillion trillion kelvins).
No. Our sun is very hot, but not as much as some other stars. The surface temperature of our sun is around 5500 to 6000 degrees Kelvin, about the same in °C. The inner core t…emperature is around 14.5 million degrees Kelvin. Blue stars are much hotter, with surface temperatures of blue hyper giant stars up to 40,000 degrees Kelvin and core temperatures of several million Kelvin. Dying Stars can be very hot at the core, as they go through the last stages of life, fusing heavier and heavier atoms. In the final stages, some super massive red hyper giants can be undergoing silicon fusion, where temperatures are up to 2,700,000,000 (2.7 billion) Kelvin. During a supernova explosion, core temperatures can reach 100 billion Kelvin. This is where heavier atoms are created such as Gold - this is only for a very short time though. Scientists on Earth have been able create huge temperatures of around 2 billion degrees through special equipment, though collisions of protons and neutrons at the CERN hadron collider are thought to create temperatures of up to 10 trillion degrees (10,000 billion) on a very small scale for very short periods of time.
The hottest stars are those that appear bluish, such as Sirius. Cygnus OB2-12 is a very bright blue hypergiant that lies between 5,000-6,000 light-years from Earth. It is …with an absolute magnitude of -12.2. It is more than 6 million times brighter than the Sun, and among the most luminous stars known in the Galaxy. The hottest star visible to the naked eye is Theta Orionis C, one of the stars illuminating the Orion nebula. It has a surface temperature of about 45,000 K. Even hotter is a star going by the rather unmemorable name of HD 93129A; which is about 7,500 light-years away. Its surface temperature is around 50,000 K. However, it's quite distant and thus can't be seen without a telescope. Over a short period of time, the Neutron Star burns at a temperature of over 1 billion degrees kelvin. However, the huge number of neutrinos it emits carries away so much energy that the temperature falls within a few years to around 1 million kelvins. For comparison, the Sun's surface temperature is about 6000 K.
Red stars are the coolest. They are usually between 3,000-6,000 degrees Fahrenheit. They include Proxima Centauri (4.2 light-years from Earth) and Betelgeuse (350-650 light-ye…ars from Earth). The cooler and smaller the star, the longer it lives. Blue stars are the hottest, but the LBV types, such as Eta Carinae (7,500 light-years from Earth) and R136a1 (163,000 light-years from Earth) are the hottest and heaviest in the universe. They could range temperatures from 50,000-100,000 degrees Fahrenheit.
The coolest star is red; then yellow; then blue. Like on a fire, the bottom of the fire is really hot so its blue. In the middle of a fire, its mostly yellow. Then, on top, it… has a little flame of red. :p
-- The core of a star, where continuous nuclear fusion is taking place. -- The rarified, stimulated material in the star's corona.
Blue Then white than yellow than red. The coolest live the longest though. The hottest are bigger that the cooler ones. When the blue ones die they turn into black holes. The …white ones turn into Neutron stars and the yellow and red stars turn into white dwarfs.
Well in our solar system, the sun, but we cant get to the end of the universe yet. So in our solar system the sun, but it is impossible to know. By the way, when a superno…va explodes, it can become as hot as 3,000,000,000 degrees Fahrenheit
They are called hypergiants and as such are o-type main sequence stars and are blue
NO, the Sun is not the hottest star. The hottest stars are the blue and white ones. The Sun is a medium sized star. The reason we find it so hot is because it is the nearest s…tar to us
The condensed universe itself, at the big bang.

The hottest stars are O type stars (aka Blue Giants) which have a temperature of greater than 30,000 kelvin and will have a colour of, as the name suggests, blue! The hottes…t stellar remnant in the universe is the Neutron Star burning on creation at a temperature of over 1 billion degrees kelvin. However, the huge number of neutrinos it emits carries away so much energy that the temperature falls within a few years to around 1 million kelvins. It would appear white to the eye.
