Which of the following nuclear fuels does a one solar mass star use over the course of its entire evolution? a. hydrogen b. hydrogen and helium c. hydrogen, helium, and carbon d. hydrogen, helium, carbon, and neon e. hydrogen, helium, carbon, neon, and oxygen
Of course, this is all just speculation. Stars with such small masses take a long, long time to run through all their hydrogen fuel. A star of 0.2 solar masses may take a trillion years to use up all its hydrogen.
Small Stars- The Life of a Star of about one Solar Mass. Small stars have a mass upto one and a half times that of the Sun. Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity.
Stars are made mostly of hydrogen and helium, which are packed so densely in a star that in the star's center the pressure is great enough to initiate nuclear fusion reactions. In a nuclear fusion reaction, the nuclei of two atoms combine to create a new atom.
For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.May 7, 2015
Our Sun will eventually exhaust its core hydrogen and evolve off the main sequence into a red giant.
A solar mass is the mass of the sun. Or, more precisely, it's 1.989 x 10^30 kilograms — about 333,000 Earths.Dec 6, 2018
Stars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. The outflow of energy from the central regions of the star provides the pressure necessary to keep the star from collapsing under its own weight, and the energy by which it shines.
Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.
hydrogenA star is a really hot ball of gas, with hydrogen fusing into helium at its core. Stars spend the majority of their lives fusing hydrogen, and when the hydrogen fuel is gone, stars fuse helium into carbon.
Over its lifetime, a low mass star consumes its core hydrogen and converts it into helium. The core shrinks and heats up gradually and the star gradually becomes more luminous. Eventually nuclear fusion exhausts all the hydrogen in the star's core.
Fusion powers stars and produces virtually all elements in a process called nucleosynthesis. The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. Hence ENERGY is released.Sep 17, 2018
During the neon burning stage, neon fuses into oxygen and magnesium. During the oxygen burning stage, oxygen forms silicon and other elements that lie between magnesium and sulfur in the periodic table.
