We present analytic formulae that approximate the evolution of stars for a wide range of mass M and metallicity Z. Stellar luminosity, radius and core mass are given as a function of age, M and Z, for all phases from the zero-age main sequence up to, and including, the remnant stages. For the most part we find continuous formulae accurate to within 5 per cent of detailed models. These formulae are useful for purposes such as population synthesis that require very rapid but accurate evaluation… Expand
The evolution of stellar mass and the implied star formation history
We present a compilation of measurements of the stellar mass density as a function of redshift. Using this stellar mass history we obtain a star formation history and compare it to the instantaneousExpand
Re-evaluating old stellar populations
Determining the properties of old stellar populations (those with age >1 Gyr) has long involved the comparison of their integrated light, either in the form of photometry or spectroscopic indexes,Expand
Evolutionary Population Synthesis for Single Stellar Populations
Using the evolutionary population synthesis technique, we present the latest integrated colours for instantaneous burst single stellar populations (SSPs) of different metallicities and we investigateExpand
The photometric evolution of dissolving star clusters: II. Realistic models. Colours and M/L ratios
Context. Evolutionary synthesis models are the primary means of constructing spectrophotometric models of stellar populations, and deriving physical parameters from observations compared with theseExpand
The photometric evolution of dissolving star clusters I. First predictions
The broad-band photometric evolution of unresolved star clusters is calculated in a simplified way, including the preferential loss of low-mass stars due to mass segregation. The stellar massExpand
Evolution of Mass Functions of Coeval Stars through Wind Mass Loss and Binary Interactions
Accurate determinations of stellar mass functions and ages of stellar populations are crucial to much of astrophysics. We analyse the evolution of stellar mass functions of coeval main sequence starsExpand
The evolution of the global stellar mass function of star clusters: an analytic description
The evolution of the global stellar mass function of star clusters is studied based on a large set of N-body simulations of clusters with a range of initial masses, initial concentrations, inExpand
Mass-luminosity relation for FGK main sequence stars: metallicity and age contributions
The stellar mass-luminosity relation (MLR) is one of the most famous empirical “laws”, discovered in the beginning of the 20th century. MLR is still used to estimate stellar masses for nearby stars,Expand
Biases in the inferred mass-to-light ratio of globular clusters: no need for variations in the stellar mass function
From a study of the integrated light properties of 200 globular clusters (GCs) in M31, Strader et al. found that the mass-to-light ratios are lower than what is expected from simple stellarExpand
Colour indices of single stellar populations
We present integrated colours for instantaneous burst single stellar populations (SSPs) of different metallicities and investigate their colour evolution. The principal difference between this studyExpand


Zero-age main-sequence radii and luminosities as analytic functions of mass and metallicity
We present fitting formulae for the zero-age main-sequence radii and luminosities of stars as functions of their masses and metallicities. The formulae cover masses from 0.1 to 100 Mo andExpand
A new technique for calculations of binary stellar evolution, with application to magnetic braking
We present a new computational technique for the study of the evolution of compact binary stellar systems with mass-losing secondaries whose masses can range between approx.0.01 M/sub sun/ andExpand
Rapid binary star evolution for N-body simulations and population synthesis
We present an algorithm for the rapid evolution of binary stars. It is based on simple fitting formulae for the evolution of single stars. Mass loss, mass transfer and common-envelope evolution areExpand
Evolution of Low- and Intermediate-Mass Stars to the End of the Asymptotic Giant Branch with Mass Loss

The Role of Binaries in the Dynamical Evolution of the Core of a Globular Cluster
The size of the core is one of the main diagnostics of the evolutionary state of a globular cluster. Much has been learned over the last few years about the behavior of the core radius during andExpand

The Luminous Blue Variables: Astrophysical Geysers
Some of the most luminous stars have sporadic, violent mass-loss events whose cuases are not understood. These evolved hot stars are called Luminous Blue Variables (LBV's), and their instability mayExpand
