  author={Dean M. Townsley and Lars Bildsten},
White dwarfs experience a thermal renaissance when they rec ive mass from a stellar companion in a binary. For accretion rates< 10M⊙ yr−1, the freshly accumulated hydrogen/helium envelope ignite s in a thermally unstable manner that results in a classical novae (CN) outbu rst and ejection of material. We have undertaken a theoretical study of the impact of the accumulating envelop n the thermal state of the underlying white dwarf (WD). This has allowed us to find the equilibrium WD core tempe… 
Hydrogen Burning on Accreting White Dwarfs: Stability, Recurrent Novae, and the Post-nova Supersoft Phase
We examine the properties of white dwarfs (WDs) accreting hydrogen-rich matter in and near the stable burning regime of accretion rates as modeled by time-dependent calculations done with Modules for
MESA Models of Classical Nova Outbursts: The Multicycle Evolution and Effects of Convective Boundary Mixing
Novae are cataclysmic variables driven by accretion of H-rich material onto a white dwarf (WD) star from its low-mass main-sequence binary companion. New time-domain observational capabilities, such
MESA and NuGrid simulations of classical novae: CO and ONe nova nucleosynthesis
Classical novae are the result of thermonuclear flashes of hydrogen accreted by CO or ONe white dwarfs, leading eventually to the dynamic ejection of the surface layers. These are observationally
GW Librae: A unique laboratory for pulsations in an accreting white dwarf
Non-radial pulsations have been identified in a number of accreting white dwarfs in cataclysmic variables. These stars offer insight into the excitation of pulsation modes in atmospheres with mixed
Comprehensive models of novae at metallicity Z = 0.02 and Z = 10−4
Novae are the observational manifestations of thermonuclear runaways on the surface of accreting white dwarfs (WDs). Although novae are an ubiquitous phenomenon, their properties at low metallicity
Evolution of helium star plus carbon-oxygen white dwarf binary systems and implications for diverse stellar transients and hypervelocity stars
Context. Helium accretion induced explosions in CO white dwarfs (WDs) are considered promising candidates for a number of observed types of stellar transients, including supernovae (SNe) of Type Ia
Constraint on Recurrent Novae as progenitors of Type Ia Supernovae
It is known that at low mass accretion rate (M_dot) the material accreted by a white dwarf (WD) is lost in classical nova (CN) explosions. However, some mass accumulation may be possible just below
Super-Eddington wind scenario for the progenitors of type Ia supernovae: Accreting He-rich matter onto white dwarfs
Supernovae of type Ia (SNe Ia) are believed to be thermonuclear explosions of carbon-oxygen white dwarfs (CO WDs). However, the mass accretion process onto CO WDs is still not completely understood.
The Massive CO White Dwarf in the Symbiotic Recurrent Nova RS Ophiuchi
If accreting white dwarfs (WD) in binary systems are to produce type Ia supernovae (SNIa), they must grow to nearly the Chandrasekhar mass and ignite carbon burning. Proving conclusively that a WD
Carbon Shell or Core Ignitions in White Dwarfs Accreting from Helium Stars
White dwarfs accreting from helium stars can stably burn at the accreted rate and avoid the challenge of mass loss associated with unstable Helium burning that is a concern for many Type Ia
