Recurrent Novae , Classical Novae , Symbiotic Novae , and Population II
Light curve analysis of decay phase of nova outburst are summarized. Nova duration is determined by the strong wind mass-loss which depends only on the white dwarf mass. Fast novae correspond very massive white dwarfs and very slow novae correspond almost lower mass limit of white dwarfs. This relation is shown in both of classical novae and recurrent novae. Light curves are theoretically repro...
متن کاملThermonuclear Runaways on Accreting White Dwarfs: Models of Classical Novae Explosions
The mechanism of classical novae explosions is explained, together with some of their observational properties. The scarce but not null impact of novae in the chemical evolution of the Milky Way is analyzed, as well as their relevance for the radioactivity in the Galaxy. A special emphasis is given to the predicted gamma-ray emission from novae and its relationship with the thermonuclear model ...
متن کاملMulti - D Simulations of the Thermonuclear Runaway on a White
We present the results of two-and three-dimensional calculations of turbulent nuclear burning of hydrogen-rich material accreted onto a white dwarf of 1.0 M. The main aim of the present paper is to investigate the question as to whether and how the general properties of the burning are aaected by dimension-ality and numerical resolution eeects. In particular, we want to see whether or not conve...
متن کاملOn the Thermonuclear Runaway in Type Ia Supernovae: How to run away?
Type Ia Supernovae are thought to be thermonuclear explosions of massive white dwarfs (WD). We present the first study of multi-dimensional effects during the final hours prior to the thermonuclear runaway which leads to the explosion. The calculations utilize an implicit, 2-D hydrodynamical code. Mixing and the ignition process are studied in detail. We find that the initial chemical structure...
متن کامل3 D Models of Thermonuclear Supernovae
In this paper, we review the present state of theoretical models of thermonuclear supernovae, and compare their predicitions with the constraints derived from observations of Type Ia supernovae. The diversity of explosion mechanisms usually found in one-dimensional simulations is a direct consequence of the impossibility to resolve the flame structure under the assumption of spherical symmetry....
