The thermalactivity (radiation pressure) stops further gravitational collapse——A main sequence star is born.聚变产生的热/辐射使得物质不能进一步受引力作用塌缩,这时恒星达到了一个相对稳定平衡的状态——main sequencestar(主系星),而恒星会在这个状态待很久很久。我们的太阳也在目前这个最稳定的状态。此刻恒星...
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...
While the population of main-sequence debris discs is well constrained, little is known about debris discs around evolved stars. This paper provides a theoretical framework considering the effects of stellar evolution on debris discs, particularly the production and loss of dust within them. Here, ...

A main sequence star has characteristics that place it on an H-R diagram's band, or main sequence. Discover features of a main sequence star and why people may have to leave Earth one day. Why We'll Have to Leave Our Planet Over a billion years from now, the Earth's oceans will ...
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...
摘要: New photometric elements are derived for V Pup by solving, in a homogeneous way, nine light curves taken from literature. The star seems to be main sequence contact binary.关键词: Astronomical Models Eclipsing Binary Stars Main Sequence Stars Astronomical Photometry Light Curve Mass Ratios ...
