The end of the super-soft X-ray phase of the recurrent nova RS Ophiuchi
Abstract
Swift X-ray telescope observations of the recurrent nova RS Oph showed a linear decline in soft X-ray flux from a plateau level between Apr 12.1 and Apr 28.7 (ATEL #801). Since then Swift observations have continued, initially at nominal intervals of 2 days, and later, 4 days. The bright super-soft X-ray phase described in ATEL #770 (also CBET #498) appears to be over. The 0.3-10 keV count rate started to flatten out from its linear decline between the observations on May 10.6 and May 14.5.
