WebbWe attempt to study the ability of asymptotic giant branch stars to produce s-process elements as a function of initial mass and metallicity. The normal methods of extracting information from spectroscopic observations of the surfaces of these stars are reviewed and it is shown how misleading some of the past claims are and which methods of … Webb8 feb. 2024 · The stellar initial mass function (IMF) describes the distribution of the initial mass of new stars in a population.

The initial mass function - Rijksuniversiteit Groningen
In astronomy, the initial mass function (IMF) is an empirical function that describes the initial distribution of masses for a population of stars during star formation. IMF not only describes the formation and evolution of individual stars, it also serves as an important link that describes the formation and evolution of … Visa mer The mass of a star can only be directly determined by applying Kepler's third law into binary stars system. However, the number of binary systems that can be observed is low, thus not enough samples to estimate the initial … Visa mer The initial mass function is typically graphed on a logarithm scale of log(N) vs log(m). Such plots give approximately straight lines with a slope Γ equal to 1-α. Hence Γ is often … Visa mer • Scalo, J. M. (1986).

Bibcode Visa mer 1.^ Different mass of stars have different ages, thus modifying the star formation history would modify the present-day mass function, which mimics the effect of modifying the IMF.
