On the main sequence massive stars quizlet
WebThe mass of the star at the time of formation determines its location on the main sequence. Main sequence stars range in mass from 0.1 to 20 times the mass of the Sun (with a few exceptions) Most main-sequence stars are low-mass stars, and only a small fraction are much more massive than the Sun The main-sequence star's radius and … Web22 de jul. de 2024 · What is a main sequence star quizlet?

Web4 de mar. de 2024 · Main-sequence stars, including the sun, form from clouds of dust and gas drawn together by gravity. How the stars evolve through their lifetime depends on their mass. The most massive... WebGlobular Clusters. Globular clusters were given this name because they are nearly symmetrical round systems of, typically, hundreds of thousands of stars. The most massive globular cluster in our own Galaxy is Omega Centauri, which is about 16,000 light-years away and contains several million stars (Figure 22.6).Note that the brightest stars in this …
Web27 de jan. de 2003 · The observable properties of main sequence stars, such as their surface temperature, luminosity, and radius, are all dictated by the massof the Thus, the main sequence is a MASS sequence. Consider taking a star and increasing its mass by pouring a little extra hydrogen gas onto it. Higher mass leads to Higher compression, … WebExpert Answer 5) Brighter than the cooler ones Explanation- The Main sequence star that are hotter are brighter than the cooler main sequence stars lying at the right extremity of the diagram. These massive stars rapidly burn their hydrogen and burn much brightly … View the full answer Transcribed image text:
WebMassive Stars When a star is more than ten times as massive as the sun, it becomes a Supergiant star. Supergiants have the shortest lifespans of any star, as the temperatures in a supergiant's core get so high that it is able to fuse the helium that is left over after hydrogen burning has stopped. WebIn other cases, in which the mass of the star is several solar masses or more, the star may explode as a supernova. Even for these more massive stars, however, if the residual …

WebThe main sequence was initially an observational discovery that If you plot stars’ absolute luminosity against their color index (strongest color radiated), most stars are found roughly along a line, with bright stars being blue and dim ones red. biology s5mcbWebMain-sequence stars below 0.4 M☉ undergo convection throughout their mass. When core convection does not occur, a helium-rich core develops surrounded by an outer layer of hydrogen. The more massive a star is, the shorter its lifespan on the main sequence. daily news horoscope weeklyWebWhat basic property of a star determines where it lies on the main sequence?
