UV turn-off times of classical novae

Gallagher, J.; Orio, M.; Gonzalez-Riestra, R.

We present IUE spectra of classical novae obtained at least one year after the outburst. The UV luminosities are compared with the ROSAT\ observations and significant parameters of the systems. The turn-off times derived from the IUE data are in agreement with the ROSAT\ results, showing that most novae decline in bolometric luminosity 1-5 years a…

The photosphere and chromosphere of the RS Canum Venaticorum star, II Pegasi. II. A multi-wavelength campaign in August/September 1992

Amado, P. J.; Doyle, J. G.; Sarro, L. M. +14 more

We describe multi-wavelength, simultaneous observations of the RS CVn star, II Pegasi, most of which were obtained during the first three weeks of September 1992. These observations were made using optical and infra-red broad-band photometry, ultraviolet and optical spectroscopy and microwave monitoring. We have detected photospheric spots and chr…
