R136a1 is the most massive known star in the universe, but it is far from unique. A 2018 study of the Tarantula Nebula, also called 30 Doradus or 30 Dor, revealed that R136a1 is not alone; the nebula hosts several other stars with the greatest masses yet detected.Jul 27, 2018
Red Dwarf Star These are main-sequence stars but they have such low mass that they're much cooler than stars like our Sun.
Our Sun is an example of a main-sequence star. It is just one of the many. In fact, they make up about 90% of all the stars in stars that populate the universe. The mass of main-sequence stars ranges from about 0.10 to 200 times the solar mass.
A supergiant is the largest known type of star; some are almost as large as our entire solar system. Betelgeuse and Rigel are supergiants.
In general, the more massive a star is, the shorter its lifespan on the main sequence. After the hydrogen fuel at the core has been consumed, the star evolves away from the main sequence on the HR diagram, into a supergiant, red giant, or directly to a white dwarf.
Which star has the largest radius? According to the notes, "stars with a higher L and lower T than the MS have larger radii and that these stars are giants and supergiants". Antares would have the largest radius because it is the supergiant on this chart.
What is a Main Sequence Star? A main sequence star is any star that has a hot, dense core which fuses hydrogen into helium to produce energy. Most stars in the galaxy are main sequence stars, including Alpha Centauri A, Tau Ceti and the Sun.Sep 27, 2021
Main sequence stars are stars that are fusing hydrogen atoms to form helium atoms in their cores.
The main sequence is the stage where a star spends most of its existence. Relative to other stages in a star's "life" it is extremely long; our Sun took about 20 million years to form but will spend about 10 billion years (1 × 1010 years) as a main sequence star before evolving into a red giant.
Which color stars have the coolest surface temperature? When a main-sequence star has exhausted the fuel in the inner region, it becomes a ________. The Sun belongs to this class of stars. The hottest main-sequence stars are also the most massive.
A massive star is a star that is larger than eight solar masses during its regular main sequence lifetime. Massive stars are born, just like average stars, out of clouds of dust called nebulae.Sep 10, 2021
UY ScutiThe largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.Feb 3, 2022
