Most stars lie on a line known as the "main sequence," which runs from the top left (where hot stars are brighter) to the bottom right (where cool stars tend to be dimmer). When the stars go out ...

Stars in the prime of their lives, known as main sequence stars, are typically classified by how hot they are. Since most star temperatures can’t be directly measured, explains Natalie Gosnell ...

The Sun is very much a main sequence star, in the G-type category (G2V to be precise). It’s been fusing hydrogen for 4.6 billion years, but it still has almost three times as much as it has helium.

Our Sun is an average main-sequence star. Astronomers estimate that it will continue fusion for another 5 billion years or so. And then there are the coolest (as in temperature) stars — red dwarfs.

As a result, more massive stars put out more light and heat as they burn their nuclear fuel at a faster pace than cooler, less massive stars. F-type main sequence stars have a mass about 10 to 60 ...

The brighter of the two is a G0V main-sequence star, very similar to our Sun. Its partner is a K7V main-sequence star. This binary — which lies only 19.4 light-years away — is also visible all ...

While our Sun is considered a main sequence star that is “alive” given its active fusion process that converts hydrogen into helium, white dwarf stars are considered “dead” stars as they have ...
