Modeling of the Super-eddington Phase for Classical Novae: Five Iue Novae
نویسندگان
چکیده
We present a light curve model for the super-Eddington luminosity phase of five classical novae observed with IUE. Optical and UV light curves are calculated based on the optically thick wind theory with a reduced effective opacity for a porous atmosphere. Fitting a model light curve with the UV 1455 Å light curve, we determine the white dwarf mass and distance to be (1.3 M⊙, 4.4 kpc) for V693 CrA, (1.05 M⊙, 1.8 kpc) for V1974 Cyg, (0.95 M⊙, 4.1 kpc) for V1668 Cyg, (1.0 M⊙, 2.1 kpc) for V351 Pup, and (1.0 M⊙, 4.3 kpc) for OS And. Subject headings: novae, cataclysmic variables — stars: individual (V693 Coronae Australis, V1974 Cygni, V1668 Cygni, V351 Puppis, OS Andromedae)

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 driven porous atmosphere. The model is then applied to derive the mass loss observed in bright classical novae. The main results are: (i) A general relation between the mass loss rate and the total ...
متن کاملClassical Novae as Super-Eddington Objects
Several of the inconsistencies plaguing the field of novae are resolved once we consider novae to be steady state super-Eddington objects. In particular, we show that the super-Eddington shell burning state is a natural consequence of the equations of stellar structure, and that the predicted mass loss in the super-Eddington state agrees with nova observations. We also find that the transition ...
متن کاملA Modeling of the Super-eddington Luminosity in Nova Outbursts: V1974 Cygni
We have modeled nova light curves exceeding the Eddington luminosity. It has been suggested that a porous structure develops in nova envelopes during the super Eddington phase and the effective opacity is much reduced for such a porous atmosphere. Based on this reduced opacity model, we have calculated envelope structures and light curves of novae. The optically thick wind model is used to simu...
متن کاملX-ray emission from classical and recurrent novae observed with ROSAT
We have analysed 350 pointed and serendipitous observations of 108 different classical and recurrent novae in outburst and in quiescence, contained in the ROSAT archive. One aim was to search for super-soft Xray sources and we found only 3 of them among postnovae. Thus, the super-soft X-ray phase of novae is relatively short lived (up to 10 years) and is observed only for up to 20% of novae. Mo...
متن کاملSuper Eddington Atmospheres and their Winds
We present a model for the steady state winds of super-Eddington systems. These radiatively driven winds are expected to be optically thick and clumpy as they arise from a porous atmosphere. The model is then used to derive the mass loss of bright classical novae. The long duration super-Eddington outflows that are clearly observed in at least two cases (Nova LMC 1988 #1 & Nova FH Ser) are natu...
