They are very hot stars.
The nearest stars - assuming all stars up to a certain distance are actually known - are representative of the general star population. The brightest stars are not. They are... brighter than the average stars.
Main Sequence blue giants such as Rigel are located on the left-hand side of the H-R diagram. The order is O B A F G K M, and these are spectral classes based on color and temperature. The hottest stars burn blue/white because blue light has the shortest wavelengths and the highest temperatures. Moderate stars like our sun, a type G star, are found in the center of the Main Sequence, and red dwarf stars are found on the right-hand end, in the K and M classes.
The largest stars would also be the brightest and that would put them near the top of the Hertzprung Russell diagram. The Sky Catalogue 2000.0 lists 50,071 stars of brightness down to magnitude 8.0. The brightest star is Rho Cassiopeiae with an absolute magnitude of -9.5, which is about 400,000 times more luminous than the Sun, and its spectrum is G2 like the Sun.
The Main Sequence refers to the H-R diagram of stellar evolution (the Hertzsprung-Russell diagram). If a star is on the Main Sequence, then it is burning with the rate and temperature expected of its spectral class. Stars are divided into the following spectral classes on the H-R diagram: O, B, A, F, G, K, M O, B and A stars burn very hot because they are very large, and they are usually white/blue-white in color F and G stars (our sun is a G star) burn moderately, are moderate in size and give off yellow light K and M stars are red dwarfs. They burn slowly with red color, representing the coolest, least energetic spectrum of light. Stars which are off the Main Sequence but which are on the H-R diagram include Red Giants (like Betelgueuse and Antares), and white dwarfs, stages at the end of a star's life cycle which our sun will eventually pass through. More massive stars have different endings, including supernovae and black holes or neutron stars. These are not on the H-R diagram.
When smaller stars explode (like our Sun), they leave a nebula cloud by releasing their gas and they become a small but dense white dwarf star.When big stars explode (like Betelgeuse), they have a massive explosion called a supernova and the core of the star turns into a black hole or a pulsar.
An H-R Diagram (Hertzsprung and Russell) is used to classify stars based on their size and brightness. The main sequence stars, such as our sun, are the medium stars, and take up the middle f the diagram, while the giants and dwarves are located on either side. http://www.eso.org/public/outreach/eduoff/cas/cas2002/cas-projects/bulgaria_comaber_1/hr_local.gif <- shows what an H-R diagram looks like.

If it is anything like my 1999 E 320; the diagram is located under the lid on the fuse box.

whats does the radiator core looks like?
the ones that are cool like meh
The stars are arranged like a saucepan, with the handle consisting of three stars to the left when it is 'upright'. Look at the link to the picture below. See related link
Youtube has changed and there are no longer stars. Now you either like or dislike using the buttons on the left directly below a video.
Stars' brightness and temperature are typically represented on a Hertzsprung-Russell (H-R) diagram. An average star like the Sun would be located on the "Main Sequence" portion of the graph, where brightness increases as temperature increases.
No he does not like stars, stars like him
