Webmore massive star that burns mainly via the CNO cycle, we have ν ≈ 20, and we instead obtain R ∝ M19/23, a nearly linear relationship. Thus we expect the radius to increase with mass as M3/7 at small masses, increasing in steepness to a nearly linear relationship at larger masses. For the density, we have ρ ∗ = M R3 ∗ = q 0κ ac R µG ... WebFeb 20, 2024 · Estimate the lifetime of a star with twice the mass of the Sun. Given: The ratio of the masses is 2:1. Concept: The lifetime goes as the inverse square of the mass: t ~ 1/M 2. Solve: So to find the ratio of the lifetimes, take the inverse square of the ratio of masses: t ~ 1/ (2/1) 2 = ¼.

WebJun 9, 2024 · Explanation: In every star, the process of nuclear fusion takes place in which four hydrogen atoms combine to form a helium atom. When enough hydrogen atoms are converted to helium then fusion of helium atoms start and new elements are made in similar way. The star begins to die when iron is produced in its core. All elements are produced in ...

WebAll stars begin life in the same way. A cloud of dust and gas, also known as a nebula, becomes a protostar, which goes on to become a main sequence star. Following this, … WebMass loss For massive stars, mass loss in stellar winds means that the present mass is smaller than the initial mass. These difficulties mean that although the local IMF is well determined for masses between ~0.5 Msun and ~50 Msun: • not well determined at the very low mass end (mainly because the relation between luminosity and mass
