TL;DR: Two XMM-Newton observations of the fast classical nova V2491Cyg were carried out in short succession on days 39.93 and 49.62 after discovery, yielding simultaneous X-ray and UV light curves and high-resolution X-rays spectra, finding a remarkable similarity in the continua of V24 91Cyg and RSOph.

TL;DR: In this article, the authors inspect all available X-ray grating SSS spectra to determine systematic, model-independent trends and find that the emission lines clearly seen in SSe may also be present in SSa, hidden within the forest of complex atmospheric absorption and emission features.

TL;DR: The Andromeda Galaxy recurrent nova M31N 2008-12a had been observed in eruption ten times, including yearly eruptions from 2008-2014 as discussed by the authors, with a measured recurrence period of $P_\mathrm{rec}=351\pm13$ days (we believe the true value to be half of this) and a white dwarf very close to the Chandrasekhar limit.
Swift detection of the super-swift switch-on of the super-soft phase in nova V745 Sco (2014)

TL;DR: V745 Sco as mentioned in this paper is a recurrent nova with the most recent eruption occurring in February 2014, which was first observed by Swift a mere 3.7 hr after the announcement of the optical discovery, with the super-soft X-ray emission being detected around four days later and lasting for only ~two days, making it both the fastest follow-up of a nova by Swift and the earliest switch-on of supersoft emission yet detected.
