Mass-loss predictions for O and B stars as a function of metallicity
- J. Vink, A. D. Koter, UK.
- Physics
- 29 January 2001
We have calculated a grid of massive star wind models and mass-loss rates for a wide range of metal abundances between 1=100 Z=Z 10. The calculation of this grid completes the Vink et al. (2000)…
Rotating massive main-sequence stars - I. Grids of evolutionary models and isochrones
- I. Brott, S. D. Mink, J. Vink
- Physics, Geology
- 2 February 2011
We present a dense grid of evolutionary tracks and isochrones of rotating massive main-sequence stars. We provide three grids with different initial compositions tailored to compare with early OB…
ON THE MAXIMUM MASS OF STELLAR BLACK HOLES
- K. Belczynski, T. Bulik, J. Hurley
- Physics
- 17 April 2009
We present the spectrum of compact object masses: neutron stars and black holes (BHs) that originate from single stars in different environments. In particular, we calculate the dependence of maximum…
Mass loss from hot massive stars
- Joachim Puls, J. Vink, Francisco Najarro
- Physics
- 4 November 2008
Mass loss is a key process in the evolution of massive stars, and must be understood quantitatively if it is to be successfully included in broader astrophysical applications such as galactic and…
The empirical metallicity dependence of the mass-loss rate of O- and early B-type stars
- M. R. Mokiem, A. D. Koter, M. R. Villamariz
- Physics
- 15 August 2007
We present a comprehensive study of the observational dependence of the mass-loss rate in stationary stellar winds of hot massive stars on the metal content of their atmospheres. The metal content of…
Predictions for mass-loss rates and terminal wind velocities of massive O-type stars
- L. Muijres, J. Vink, A. D. Koter, P. Mueller, N. Langer
- Physics
- 5 December 2011
Context. Mass loss from massive stars forms an important aspect of the evolution of massive stars, as well as for the enrichment of the surrounding interstellar medium. Aims. Our goal is to predict…
Sub-surface convection zones in hot massive stars and their observable consequences
- M. Cantiello, N. Langer, S.-C. Yoon
- Physics
- 11 March 2009
Context. We study the convection zones in the outer envelope of hot massive stars which are caused by opacity peaks associated with iron and helium ionization. Aims. We determine the occurrence and…
The R136 star cluster dissected with Hubble Space Telescope/STIS. I. Far-ultraviolet spectroscopic census and the origin of He II λ1640 in young star clusters
- P. Crowther, S. Caballero-Nieves, J. Vink
- Physics
- 16 March 2016
We introduce a Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) stellar census of R136a, the central ionizing star cluster of 30 Doradus. We present low resolution…
An excess of massive stars in the local 30 Doradus starburst
- F. Schneider, H. Sana, C. Norman
- Physics, GeologyScience
- 5 January 2018
The recent formation history and the initial mass function (IMF) of massive stars in 30 Doradus is determined on the basis of spectroscopic observations of 247 stars more massive than 15 solar masses, and the main episode of massive star formation began about 8 million years ago and seems to have declined in the last 1 My.
The VST Photometric Hα Survey of the Southern Galactic Plane and Bulge (VPHAS

- Physics
- 27 February 2014
The VST Photometric HSurvey of the Southern Galactic Plane and Bulge (VPHAS+) is surveying the southern Milky Way in u,g,r,i and Hat �1 arcsec angular resolution. Its footprint spans the Galactic…
