Complex Velocity Fields in the Shell of T Pyxidis
We present spatially-resolved, moderate-resolution spectrophotometry of the recurrent nova T Pyx and a portion of the surrounding shell. The spectrum extracted from a strip of width 10′′ centered on the star shows well-known, strong emission lines typical of old novae, plus a prominent, unfamiliar emission line at λ6590. This line, and a weaker companion at λ6540 which we also detect, have been...
متن کاملAssisted stellar suicide: the wind-driven evolution of the recurrent nova T Pyxidis
We show that the extremely high luminosity of the short-period recurrent nova T Pyx in quiescence can be understood if this system is a wind-driven supersoft x-ray source (SSS). In this scenario, a strong, radiationinduced wind is excited from the secondary star and accelerates the binary evolution. The accretion rate is therefore much higher than in an ordinary cataclysmic binary at the same o...
متن کاملThe Nova Shell and Evolution of the Recurrent Nova T Pyxidis
T Pyxidis is the prototypical recurrent nova (RN) with five eruptions from 1890 to 1967 and a mysterious nova shell. We report here on new observations of the nova shell with the Hubble Space Telescope (HST) in the year 2007, which provides a long time baseline from earlier HST images in 1994 and 1995. We find that the knots in the nova shell are expanding with velocities ranging from roughly 5...
متن کاملThe 2011 outburst of the recurrent nova T Pyxidis. Evidence for a face-on bipolar ejection
Aims. T Pyx is the first recurrent nova ever historically studied. It was seen in outburst six times between 1890 and 1966 and then not for 45 years. We report on near-IR interferometric observations of the recent outburst of 2011. Methods. We obtained near-IR observations of T Pyx at dates ranging from t = 2.37 d to t = 48.2 d after the outburst, with the CLASSIC recombiner located at the CHAR...
متن کاملcontribution of setting to the study of characters and the main idea in e. brontes: wuthering heights and t. hardys: return of the native.
this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...
