A main sequence star is a star in the stable part of its life cycle. They are the most common type of star in the universe. Our star, the Sun, is in the main sequence phase. It is about halfway through this stage, and ultimately will become a red giant in roughly five billion yea...
What Is a Main Sequence Star? A star whose characteristics place it in a band, called the main sequence, on an H-R diagram is called a main sequence star. The Hertzsprung-Russell (H-R) diagram is a diagram that plots a star's luminosity vs. surface temperature. Luminosity is the ...
A. Its distance from other stars B. Its age C. Its mass D. The amount of dust around it 相关知识点: 试题来源: 解析 C。解析:The size and brightness of a main-sequence star depend on its mass.表明主序星的大小和亮度取决于它的质量。反馈...
Here, you may ask what a main sequence star is. OK...the main sequence refers to a major grouping of stars that uh... forms a relatively narrow band from the upper left to the lower right, when plotted according to luminosity, that is, how bright it is, and surface temperature, on...
The Sun is an example of a yellow dwarf, also known as a main-sequence star. When a star begins its main sequence life, it is fusing hydrogen to helium within the core. Throughout the life cycle, the core begins to be depleted of hydrogen. As the composition of the core changes, ...
Why will Polaris not always be the North Star? What constellation is the star Vega in? Is Polaris a main sequence star? What is the brightest star in the constellation Orion? What constellation is the Orion nebula in? What is the brightest star in the northern hemisphere?

24, and it’s what’s left of what was once a red giant star and, before that, a main sequence star in the prime of its life. Now, it’s a white-hot ball of matter a fraction of its original size, and the colossal blast of gas surrounding it is the star’s “last breath.”...
Main Sequence Star: The majority of all stars in our galaxy, and even the Universe, are main sequence stars. Our Sun is a main sequence star, and so are our nearest neighbors, Sirius and Alpha Centauri A. Main sequence stars can vary in size, mass and brightness, but they’re all doi...
Surprisingly, the Sun is classed as aDwarf Stareven though it's bigger than 70% of stars in the galaxy. Dwarf Stars usually refer to averaged, normal main sequence stars, like our Sun. A White Dwarf is the result of a death of a small star that wasn't big enough to gosupernova. ...
