The recurrent nova IM Nor was observed twice in X-rays with the Chandra ACIS-S, 1 and 6 months after the optical outburst. It was not detected in the first observation, with an upper limit on the X-ray luminosity in the 0.2-10 keV range LX < 4.8 × 1030(d kpc-1)2 ergs s-1 (where d is the distance to the nova). Five months later, a hard X-ray source with LX = × 1032(d kpc)2 ergs s-1 was detected. The X-ray spectrum appears to be thermal, but we cannot rule out additional components due to…

Swift observations of the X-ray and UV evolution of V2491 Cyg (Nova Cyg 2008 No. 2)
TLDR
Observing the X-ray emission from only one day after the nova discovery, the source is followed through the initial brightening, the super-soft source phase and back to the pre-outburst flux level, demonstrating the evolution of the spectrum throughout the outburst.
Novae as a Class of Transient X-Ray Sources
Motivated by the recently discovered class of faint (1034-1035 ergs s−1) X-ray transients in the Galactic center region, we investigate the 2-10 keV properties of classical and recurrent novae.
The XMM-Newton detection of extended emission from the nova remnant of T Pyxidis
We report the detection of an extended X-ray nebulosity with an elongation from north-east to south-west in excess of 15 arcsec in a radial profile and imaging of the recurrent nova T Pyx using the
SWIFT X-RAY OBSERVATIONS OF CLASSICAL NOVAE. II. THE SUPER SOFT SOURCE SAMPLE
TLDR
Swift observations of 52 Galactic/Magellanic Cloud novae are presented indicating that additional factors beyond the white dwarf mass and binary separation play important roles in the evolution of a nova outburst and two optical phenomena are confirmed that are correlated with strong, soft X-ray emission which can be used to further increase the efficiency ofX-ray campaigns.
Observations of galactic and extragalactic novae
The recent GAIA DR2 measurements of distances to galactic novae have allowed to re-analyse some properties of nova populations in the Milky Way and in external galaxies on new and more solid

Aims. We compare the observed and theoretical parameters for the quiescent and outburst phases of the recurring nova T Pyx. Methods. IUE data were used to derive the disk luminosity and the mass
COMPREHENSIVE PHOTOMETRIC HISTORIES OF ALL KNOWN GALACTIC RECURRENT NOVAE
I collect virtually all photometry of the 10 known galactic recurrent novae (RNe) and their 37 known eruptions. This consists of my modern measures of nearly all archival plates (providing the only

Abstract Recurrent novae (RNe) belong to the group of cataclysmic variables that exhibit nova outbursts at intervals on the order of decades. They are rare, with 10 Galactic RNe known to date. Two
A new catalogue of Galactic novae: investigation of the MMRD relation and spatial distribution
In this study, a new Galactic novae catalogue is introduced collecting important parameters of these sources such as their light curve parameters, classifications, full width half maximum (FWHM) of

V4743 Sagittarii (Nova Sgr 2002 No. 3) was discovered on 2002 September 20. We obtained a 5 ks ACIS-S spectrum in 2002 November and found that the nova was faint in X-rays. We then obtained a 25 ks
