What determines the color of a main sequence star?
Temperature translates to color, and this relationship between color and brightness (luminosity) for hydrogen-burning stars is called the main sequence. Massive hydrogen-burning stars are blue-white, the Sun is yellow, and low-mass stars are orange and red.
What does the color of a star tell you about the star?
A star’s color is critical in identifying the star, because it tells us the star’s surface temperature in the black body radiation scale. The sun has a surface temperature of 5,500 K, typical for a yellow star. The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.
How do white dwarfs produce light?
Their small size makes white dwarfs difficult to find. No white dwarfs can be seen with the unaided eye. The light they generate comes from the slow, steady release of prodigious amounts of energy stored up after billions of years spent as a star’s nuclear powerhouse. White dwarfs are born when a star shuts down.
Why is there no fusion in a white dwarf?
Usually, white dwarfs are composed of carbon and oxygen (CO white dwarf). Stars of very low mass will not be able to fuse helium, hence, a helium white dwarf may form by mass loss in binary systems. The material in a white dwarf no longer undergoes fusion reactions, so the star has no source of energy.

Which star is the youngest?
Surviving a Powerful Event. In a report by Futurism, a team of astronomers observed what they believe is the youngest neutron star 170,000 light-years away from Earth in a satellite galaxy of our very own Milky Way, which is known as SN 1987A.
