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 winds. In order for a massive star to become a Wolf-Rayet star, it must shed its hydrogen envelope, but new estimates of the effects of clumping in winds from O-type stars indicate that line driving is vastly insufficient. We discuss massive stars above roughly 40-50 M☉, which do not become red supergiants and…

Mass loss from hot massive stars

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

Mass Loss: Its Effect on the Evolution and Fate of High-Mass Stars

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 standard

Evidence suggests a clear continuum in pre-SN mass loss from super-luminous S Ne IIn, to regular SNe I in, to SNe II-L and II-P, whereas most stripped-envelope SNe seem to arise from a separate channel of lower-mass binary stars rather than massive WR stars.

Abstract I review recent progress on understanding eruptions of unstable massive stars, with particular attention to the diversity of observed behavior in extragalatic optical transient sources that

A giant outburst two years before the core-collapse of a massive star

It is reported that the peculiar type Ib supernova SN 2006jc is spatially coincident with a bright optical transient that occurred in 2004, andSpectroscopic and photometric monitoring of the supernova leads us to suggest that the progenitor was a carbon-oxygen Wolf–Rayet star embedded within a helium-rich circumstellar medium.

Revealing evolved massive stars with Spitzer

Massive evolved stars lose a large fraction of their mass via copious stellar wind or instant outbursts. During certain evolutionary phases, they can be identified by the presence of their

Spectroscopy of complete populations of Wolf-Rayet binaries in the Magellanic Clouds

Abstract Classical Wolf-Rayet stars are evolved, hydrogen depleted massive stars that exhibit strong mass-loss. In theory, these stars can form either by intrinsic mass loss (stellar winds or

Relic proto-stellar discs and the origin of luminous circumstellar interaction in core-collapse supernovae

A small fraction of core-collapse supernovae (SNe) show evidence that the outgoing blast wave has encountered a substantial mass ∼1–10 M⊙ of circumstellar matter (CSM) at radii ∼102–103 au, much more

Instabilities in the Envelopes and Winds of Very Massive Stars

The high luminosity of Very Massive Stars (VMS) means that radiative forces play an important, dynamical role both in the structure and stability of their stellar envelope, and in driving strong

Outbursts of luminous blue variable stars from variations in the helium opacity

Three-dimensional simulations of the convective envelopes of massive stars suggest that it is the helium opacity that controls outbursts in luminous blue variable stars.



Massive Stars in the Quintuplet Cluster

We present near-infrared photometry and K-band spectra of newly identified massive stars in the Quintuplet cluster, one of the three massive clusters projected within 50 pc of the Galactic center. We

How Massive Single Stars End Their Life

How massive stars die—what sort of explosion and remnant each produces—depends chiefly on the masses of their helium cores and hydrogen envelopes at death. For single stars, stellar winds are the

Studies of luminous stars in nearby galaxies. III. Comments on the evolution of the most massive stars in the Milky Way and the large magellanic cloud

An empirical comparison of the observed H-R diagrams for the supergiants in our region of the Galaxy and the Large Magellanic Cloud reveals comparable distributions of spectral types and luminosities

We have analyzed the far-ultraviolet spectrum of two Galactic O4 stars, the O4If+ supergiant HD 190429A and the O4V((f)) dwarf HD 96715, using archival FUSE and IUE data. We have conducted a

X-ray emission lines from inhomogeneous stellar winds

It is commonly adopted that X-rays from O stars are produced deep inside the stellar wind, and transported outwards through the bulk of the expanding matter which attenuates the radiation and affects

Line-driven Stellar Winds: The Dynamical Role of Diffuse Radiation Gradients and Limitations to the Sobolev Approach

Line-driven stellar winds from hot, luminous OB stars have been most extensively modeled as smooth, steady state, supersonic outflows for which a local, Sobolev line-transfer treatment is used to
