Description
We find a strong correlation between the optical outburst amplitude and
orbital period for the soft X-ray transient sources with orbital periods
less than 1 d. By fitting the observed values for eight X-ray
transients, we determine an empirical relation that can be used to
predict the orbital period of an X-ray transient given only its outburst
amplitude. For periods less than 12 h we determine a relation for the
absolute magnitude of the accretion disk during outburst, which then
allows us to estimate the distances to the sources.
