Stellar Winds from Massive Stars
We review the various techniques through which wind properties of massive stars – O stars, AB supergiants, Luminous Blue Variables (LBVs), Wolf-Rayet (WR) stars and cool supergiants – are derived. The wind momentum-luminosity relation (e.g. Kudritzki et al. 1999) provides a method of predicting mass-loss rates of O stars and blue supergiants which is superior to previous parameterizations. Assu...
متن کاملThe populations of comet-like bodies in the Solar system
A new classification scheme is introduced for comet-like bodies in the Solar system. It covers the traditional comets as well as the Centaurs and Edgeworth–Kuiper belt objects. At low inclinations, close encounters with planets often result in near-constant perihelion or aphelion distances, or in perihelion–aphelion interchanges, so the minor bodies can be labelled according to the planets pred...
متن کاملModeling Ejecta of Massive Stars
In this review I describe the various ways in which massive stars can shed matter. At first take, these stars seem to share little in common with the planetary nebula phenomenon. Their mass loss typically takes the form of periods of continuous outflow, rather than the discrete outbursts that form PNe shells. Nevertheless, the ejecta of massive stars tend to be highly structured in space and in...

متن کاملSpectroscopic analysis of early-type stars in young stellar groups
We explore the potential of analysing fast rotating early-type stars differentially with respect to templates derived from a slowly rotating star of the same spectral type. The analysis is successfully applied to the normalB1Vstars inNGC 2244, which have projected rotational velocities ranging from 22 to 260 km s−1. A classical non-LTE analysis of the slow rotator #201 results in chemical abund...
