Here we use present-day eccentricities of the observed exoplanet population to reconstruct the initial mass function of exoplanets before the onset of dynamical instability. We developed a ...

Astronomers use an initial mass function (IMF) to calculate the numbers of different kinds of stars in any given galaxy, but what’s not been clear is whether the IMF applies to all galaxies of ...

In his pioneering 1955 study 1, Salpeter proposed an empirical function, called the stellar initial mass function (IMF), that describes the initial distribution of stellar masses for a population ...
