New Insights into the Evolution of Massive Stars and Their Effects on Our Understanding of Early Galaxies
TLDR
In this paper , the authors review the current state of the art in modelling of massive star dominated stellar populations, and discuss their applications and implications for interpreting the distant Universe, including the role of the rare low metallicity starbursts nearby.Abstract:
The observable characteristics and subsequent evolution of young stellar populations is dominated by their massive stars. As our understanding of those massive stars and the factors affecting their evolution improves, so our interpretation of distant, unresolved stellar systems can also advance. As observations increasingly probe the distant Universe, and the rare low metallicity starbursts nearby, so the opportunity arises for these two fields to complement one another, and lead to an improved conception of both stars and galaxies. Here we review the current state of the art in modelling of massive star dominated stellar populations, and discuss their applications and implications for interpreting the distant Universe. Our principle findings include:read more

Theory and Diagnostics of Hot Star Mass Loss.
TL;DR: In this article, the traditional line-driven wind theory is updated with Monte Carlo and co-moving frame computations, revealing a rich multi-variate behaviour of the mass-loss rate dM/dt in terms of M, L, Eddington Gamma, Teff, and chemical composition Z.

The Luminosity function and stellar evolution
TL;DR: In this paper, the evolutionary significance of the observed luminosity function for main-sequence stars in the solar neighborhood is discussed and it is shown that stars move off the main sequence after burning about 10 per cent of their hydrogen mass and that stars have been created at a uniform rate in a solar neighborhood for the last five billion years.

Classification parameters for the emission-line spectra of extragalactic objects
TL;DR: In this paper, the merits of various emission-line intensity ratios for classifying the spectra of extragalactic objects were investigated and it was shown empirically that several combinations of easily-measured lines can be used to separate objects into one of four categories according to the principal excitation mechanism: normal H II regions, planetary nebulae, objects photoionized by a power-law continuum, and objects excited by shock-wave heating.
