Abstract:
Our goal is to detail the development of RS Ophiuchi and the other
Galactic symbiotic-like recurrent novae throughout their outburst and
quiescence, with a particular emphasis on the propagation of the shock
wave during the outburst of the binaries.
The spectral analysis has been performed using archival data according
to the features of the individual datasets. Swift grism spectra were
reduced and extracted using a combination of the pre-existing UVOTPY
Python routine and newly written pipelines in Matlab. Other datasets
were directly available in reduced form, already corrected for
instrumental or background contamination, and calibrated in wavelength
and flux or intensity. The work on these was done through pipelines
suited for reading the data and elaborating them to extract quantities
of interest for the analysis.
We find striking similarities in different outbursts of the same
object and for different novae. For example, RS Oph 2021 was almost
identical to the 2006 outburst, despite having occurred at a different
orbital phase with the observations made from a different line of
sight through the red giant wind. Despite the intrinsically different
properties of the binaries, striking similarities are found for
different systems of the same class, for instance, the trend of the
electron density over time during outburst appears to follow a general
temporal development.
