WebbThe initial mass function (IMF) is an important product of the star formation process (see the recent review by Lee et al., 2024). For high-mass stars, accretion plays a … WebbStars eventually evolve off the MS after a certain age, so the present-day MF (PDMF) of MS stars, which can be de-termined from the observed present-day LF, differs from the so-called initial mass function (IMF), i.e., the number of stars that were originally created per mass interval in the Galaxy.
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).
