We review the physics of continuum-driven mass loss and its likely role in η Carinae and LBVs. Unlike a line-driven wind, which is inherently limited by self-shadowing, continuum driving can in principle lead to mass-loss rates up to the “photon-tiring” limit, for which the entire luminosity is expended in lifting the outflow. We discuss how instabilities near the Eddington limit give rise to a clumped atmosphere, and how the associated “porosity” can regulate a continuum-driven flow. We also… 
Chapter 12 Instability & Mass Loss near the Eddington Limit
We review the physics of continuum-driven mass loss and its likely role in η Carinae and LBVs. Unlike a line-driven wind, which is inherently limited by self-shadowing, continuum driving can in
Radiation hydrodynamic instability in a plane-parallel, super-Eddington atmosphere: A mechanism for clump formation
In order to understand the physical processes underlying clump formation in outflow from supercritical accretion flow, we performed two-dimensional radiation hydrodynamic (RHD) simulations. We focus
Radiation-Driven Stellar Eruptions
Very massive stars occasionally expel material in colossal eruptions, driven by continuum radiation pressure rather than blast waves. Some of them rival supernovae in total radiative output, and the
The Nature of Super-Eddington Outflow around Black Holes
In this Ph.D thesis we firstly demonstrate the unique and interesting features of super-Eddington outflow around black holes based on global radiation hydrodynamic (RHD) and radiation
Numerical modeling of the 1840s major eruption of η Carinae as an explosion
In this paper, new two-dimensional hydrodynamical simulations of η Car’s nebulae are performed. In the 1840s, the massive star η Car suffered a major eruption that resulted in the formation of a
SN Hunt 248: a super-Eddington outburst from a massive cool hypergiant
We present observations of SN Hunt 248, a new supernova (SN) impostor in NGC 5806, which began a multistage outburst in 2014 May. The ‘2014a’ discovery brightening exhibited an absolute magnitude of
Was the nineteenth century giant eruption of Eta Carinae a merger event in a triple system
We discuss the events that led to the giant eruption of Eta Carinae, and find that the mid-nineteenth century (in 1838-1843) giant mass-loss outburst has the characteristics of being produced by the
Multiple giant eruptions and X-ray emission in the recoiling AGN/LBV candidate SDSS1133
We present a comprehensive analysis of 20 years worth of multi-color photometric light curves, multi-epoch optical spectra, and X-ray data of an off-nuclear variable object SDSS1133 in Mrk 177 at z =
On the Social Traits of Luminous Blue Variables
In a recent paper, Smith and Tombleson (2015) state that the Luminous Blue Variables (LBVs) in the Milky Way and the Magellanic Clouds are isolated; that they are not spatially associated with young
Giant eruptions of very massive stars
Giant eruptions or supernova-impostor events are far more mysterious than true supernovae. An extreme example can release as much radiative energy as a SN, ejecting several M_sun of material. These

A POROSITY-LENGTH FORMALISM FOR PHOTON-TIRING-LIMITED MASS LOSS FROM STARS ABOVE THE EDDINGTON LIMIT
We examine radiatively driven mass loss from stars near and above the Eddington limit. Building on the standard CAK theory of driving by scattering in an ensemble of lines with a power-law
Continuum‐Driven Winds from Super‐Eddington Stars: A Tale of Two Limits
Continuum driving is an effective method to drive a strong stellar wind. It is governed by two limits: the Eddington limit and the photon‐tiring limit. A star must exceed the effective Eddington
Numerical simulations of continuum-driven winds of super-Eddington stars
We present the results of numerical simulations of continuum-driven winds of stars that exceed the Eddington limit and compare these against predictions from earlier analytical solutions. Our models

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
The theory of steady‐state super‐Eddington winds and its application to novae
We present a model for steady state winds of systems with super-Eddington luminosities. These radiatively driven winds are expected to be optically thick and clumpy as they arise from an instability

Radiation pressure-dominated accretion disks are predicted to exhibit strong density inhomogeneities on scales much smaller than the disk scale height as a result of the nonlinear development of

TLDR
It is shown that by using the classical stellar atmosphere and wind theory, it is impossible to construct a consistent wind model in which a sufficiently small amount of mass is shed to drive a thick wind with a mass-loss rate substantially higher than the observed one.

We examine the local conditions for radiative damping and driving of short-wavelength, propagating hydrodynamic and magnetohydrodynamic (MHD) waves in static, optically thick, stratified equilibria.

The formation of 'photon bubbles' in a convectively stable scattering atmosphere supported against gravity entirely by radiation pressure is studied by means of linear stability theory. A simple
