Fine structure constant of gravitation

< 1 2 3 >

The fine structure constant of gravitation α_G determines the limiting masses of collapsing stars. The value is

α_G = 6 × 10^-39

This physical constant is dimensionless and has the same value in all unit systems

wherein

    m_p Proton mass

    G Gravitational constant

    ℏ Reduced Planck's constant

    c Speed of light

The Indian physicist Subrahmanyan Chandrasekhar (1910 - 1995) researched the inner structure of stars.
