    Comments: Accepted for publication in the book "Reviews in Frontiers of Modern Astrophysics: From Space Debris to Cosmology" (eds Kabath, Jones and Skarka; publisher Springer Nature) funded by the European Union Erasmus+ Strategic Partnership grant "Per Aspera Ad Astra Simul" . The characteristics of the emission spectra revealed two distinct types of activity. One was the relatively slow ionized wind of the Mira star. The other looked like the fast expanding ejecta of a nova outburst. In fact, the spectrum looked remarkably similar to the symbiotic recurrent novae, RS Ophiuchi.

Their light curves are generally very broad and extended, occasionally also extremely luminous and referred to as a superluminous supernova. These light curves are produced by the highly efficient conversion of kinetic energy of the ejecta into electromagnetic radiation by .

Abstract This monograph contains light curves of the recurrent nova-type cataclysmic variable star RS Ophiuchi from through (JD ). The AAVSO long-term light curve of RS Ophiuchi for this interval is presented. This light curve has been included to give a more complete picture of RS Ophiuchi's behavior.

On 12 Februarythe recurrent nova RS Ophiuchi erupted for the first time sinceits 6th (at least!) known eruption. This event triggered an intensive multi-wavelength observational campaign, from the radio to gamma-rays, and theoreticians have been presented with a wealth of high-quality data.

Radio observations of novae provide direct information about masses, temperatures, and velocities of ejected material, particularly when the radio remnants are resolved or imaged.

Every 20 years or so, the red giant star dumps enough hydrogen gas onto its companion white dwarf star to set off a brilliant thermonuclear explosion on the white dwarf's surface.

The two light curves above are formed from observations made by Tony Markham. In each case, the variables were observed on a regular basis, rather than only at the times of predicted primary eclipses, and all observations were plotted in order to see how much scatter/tidy a light curve might result.

Aug 28,  · These light curves have an average decay rate of magnitudes per day; much lower than the decay rate for Type I supernovae.

Type II are sub-divided into two classes, depending on whether there is a plateau in their light curve (Type II-P) or a linear decay rate (Type II-L).

by increasing the light-gatheringpower of the spectrometer. Use of the CCO provides an extra advantage since it is possible, at the data reduction stage, to rebin the spectra in the direction per­ pendicular to the dispersion up to about 50 to pixels thereby increasing the S/N by a large factor.
