Abstract:
We present a statistical study of all measurable photometric features
of a large sample of dwarf novae during their outbursts and
superoutbursts. We used all accessible photometric data for all our
objects to make the study as complete and up to date as possible. Our
aim was to check correlations between these photometric features in
order to constrain theoretical models which try to explain the nature
of dwarf novae outbursts. We managed to confirm a few of the known
correlations, that is the Stolz and Schoembs relation, the Bailey
relation for long outbursts above the period gap, the relations
between the cycle and supercycle lengths, amplitudes of normal and
superoutbursts, amplitude and duration of superoutbursts, outburst
duration and orbital period, outburst duration and mass ratio for
short and normal outbursts, as well as the relation between the rise
and decline rates of superoutbursts. However, we question the
existence of the Kukarkin-Parenago relation but we found an analogous
relation for superoutbursts. We also failed to find one presumed
relation between outburst duration and mass ratio for superoutbursts.
This study should help to direct theoretical work dedicated to dwarf
novae.
Description:
In this study, we used the following available catalogue data sources.
The catalogue and atlas of CVs
(https://archive.stsci.edu/prepds/cvcat/) by Downes et al.
(2001PASP..113..764D 2001PASP..113..764D, Cat. V/123) which contains 1830 objects that
have been classified as a CV before 2006 February 1, when the
catalogue was frozen.
Catalogue of cataclysmic binaries, low-mass X-ray binaries and related
objects (http://www.mpa-garching.mpg.de/RKcat/) by Ritter & Kolb
(2003A&A...404..301R 2003A&A...404..301R, Cat. B/cb). Although the reference corresponds
to a catalogue which is over 10yr old, its newest edition 7.21 (2013
December 31) has been used in this study. This catalogue contains 1094
CVs.
Catalogue of J. Patterson, that is the supplementary electronic
material to the publication Patterson (2011) containing properties of
292 non-magnetic CVs with orbital periods smaller than 3h
(http://cbastro.org/dwarfnovashort/)
