Helium Nova on a Massive White Dwarf
The 2000 outburst of V445 Puppis shows unique properties, such as absence of hydrogen, enrichment of helium and carbon, slow development of the light curve with a small amplitude that does not resemble any classical novae. This object has been suggested to be the first example of helium novae. We calculate theoretical light curves of helium novae and reproduce the observational light curve of V...
متن کاملjohn steinbeck: friend of the american common man
in his last years of life americans had almost forgotton steinbeck, and those who had not, occasionally criticized him for supporting and praising the u. s. military intervention in the vietnam war. althought ateinbeck incorporates different themes into his works, each one bears many signs of his concern and sympathy for america and the american common people in particular. steinbecks to a god ...
15 صفحه اولWhite Dwarf Heating and Subsequent Cooling in Dwarf Nova Outbursts
We follow the time dependent thermal evolution of a white dwarf (WD) undergoing sudden accretion in a dwarf nova outburst, using both simulations and analytic estimates. The post-outburst lightcurve clearly separates into early times when the WD flux is high, and late times when the flux is near the quiescent level. The break between these two regimes, occurring at a time of order the outburst ...
متن کاملThe massive white dwarf in the recurrent nova T CrB
We have obtained I, J , H and K band light curves of the recurrent nova T CrB. We find that we can only fit the J band light curve with a Roche-lobe filling secondary star and a dark spot of radius 11–26 (90 per cent confidence) centred at the inner Lagrangian point. We obtain limits to the binary inclination of 38–46 (90 per cent confidence) which when combined with the value for the mass func...
متن کاملFar Ultraviolet Study of the Hot White Dwarf in the Dwarf Nova WW Ceti
We present a synthetic spectral analysis of IUE archival and FUSE FUV spectra of the peculiar dwarf nova WW Ceti. During the quiescence of WW Ceti, a white dwarf with Twd ∼ 26, 000K ±1000K can account for the FUV flux and yields the proper distance. However, the best agreement with the observations is provided by a twotemperature white dwarf model with a cooler white dwarf at Twd = 25, 000K pro...
