Mass loss from hot massive stars

J Puls, JS Vink, F Najarro - The Astronomy and Astrophysics Review, 2008 - Springer
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 …

Mass loss: its effect on the evolution and fate of high-mass stars

N Smith - Annual Review of Astronomy and Astrophysics, 2014 - annualreviews.org
Our understanding of massive star evolution is in flux due to recent upheavals in our view of
mass loss and observations of a high binary fraction among O-type stars. Mass-loss rates for …

A new calibration of stellar parameters of Galactic O stars

F Martins, D Schaerer, DJ Hillier - Astronomy & Astrophysics, 2005 - aanda.org
We present new calibrations of stellar parameters of O stars at solar metallicity taking non-
LTE, wind, and line-blanketing effects into account. Gravities and absolute visual …

The two young star disks in the central parsec of the galaxy: properties, dynamics, and formation

T Paumard, R Genzel, F Martins… - The Astrophysical …, 2006 - iopscience.iop.org
We report the definite spectroscopic identification of≃ 40 OB supergiants, giants, and main-
sequence stars in the central parsec of the Galaxy. Detection of their absorption lines has …

Atmospheric NLTE-models for the spectroscopic analysis of blue stars with winds-II. Line-blanketed models

J Puls, MA Urbaneja, R Venero, T Repolust… - Astronomy & …, 2005 - aanda.org
We present new or improved methods for calculating NLTE, line-blanketed model
atmospheres for hot stars with winds (spectral types A to O), with particular emphasis on fast …

On the role of continuum-driven eruptions in the evolution of very massive stars and population III stars

N Smith, SP Owocki - The Astrophysical Journal, 2006 - iopscience.iop.org
We suggest that the mass lost during the evolution of very massive stars may be dominated
by optically thick, continuum-driven outbursts or explosions, instead of by steady line-driven …

The VLT-FLAMES Tarantula Survey-XII. Rotational velocities of the single O-type stars

OH Ramírez-Agudelo, S Simón-Díaz, H Sana… - Astronomy & …, 2013 - aanda.org
Context. The 30 Doradus (30 Dor) region of the Large Magellanic Cloud, also known as the
Tarantula nebula, is the nearest starburst region. It contains the richest population of …

The empirical metallicity dependence of the mass-loss rate of O-and early B-type stars

MR Mokiem, A De Koter, JS Vink, J Puls… - Astronomy & …, 2007 - aanda.org
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 discordance of mass-loss estimates for galactic O-type stars

AW Fullerton, DL Massa, RK Prinja - The Astrophysical Journal, 2006 - iopscience.iop.org
We have determined accurate values of the product of the mass-loss rate and the ion
fraction of P+ 4, dot M q (P+ 4), for a sample of 40 Galactic O-type stars by fitting stellar wind …

Stellar and wind parameters of Galactic O-stars-The influence of line-blocking/blanketing

T Repolust, J Puls, A Herrero - Astronomy & Astrophysics, 2004 - aanda.org
We have re-analyzed the Galactic O-star sample from [CITE] by means of line-blanketed
NLTE model atmospheres in order to investigate the influence of line-blocking/blanketing on …
