We present time-series photometric and spectroscopic data for seven old novae. They are used to derive the orbital period for the systems V365 Car (5.35 h), AR Cir (5.14 h), V972 Oph (6.75 h), HS Pup (6.41 h), V373 Sct (3.69 h), V909 Sgr (3.43 h) and CN Vel (5.29 h). Their addition increases the number of orbital periods for novae by �10 per cent. The eclipsing nature of V909 Sgr is confirmed, and in three other cases (V365 Car, Ar Cir and V373 Sct) we detect significant photometric orbital… 
SALT observations of southern post-novae
We report on recent optical observations of the stellar and the nebular remnants of 22 southern post-novae. In this study, for each of our targets, we obtained and analysed long-slit spectra in the
Transients from the Cataclysmic Deaths of Cataclysmic Variables
We explore the observational appearance of the merger of a low-mass star with a white dwarf (WD) binary companion. We are motivated by recent work finding that multiple tensions between the observed
Binary central stars of planetary nebulae identified with Kepler/K2
We present the identification of 34 likely binary central stars (CSs) of planetary nebulae (PNe) from Kepler/K2 data, seven of which show eclipses. Of these, 29 are new discoveries. Two additional
Life after eruption VIII: The orbital periods of novae
The impact of nova eruptions on the long-term evolution of Cataclysmic Variables(CVs) is one of the least understood and intensively discussed topics in the field. Acrucial ingredient to improve with
Automated Classification of Massive Spectra Based on Enhanced Multi-Scale Coded Convolutional Neural Network
The enhanced multi-scale coded convolutional neural network (EMCCNN) is proposed and implemented, which can perform spectral denoising and feature extraction at different scales in a more efficient manner.
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

Three-dimensional simulations of the interaction between the nova ejecta, the accretion disk, and the companion star
Context. Classical novae are thermonuclear explosions hosted by accreting white dwarfs in stellar binary systems. Material piles up on top of the white dwarf star under mildly degenerate conditions,
The distances of the Galactic novae
Utilising the unique location of red clump giants on colour-magnitude diagrams obtained from various near-IR surveys, we derived specific reddening-distance relations towards 119 Galactic novae for


Inclination and orbital-phase-dependent resonance line-profile calculations applied to cataclysmic variable winds
The implications of IUE resonance-line profiles of novalike variables and dwarf novae in outburst for theoretical models in which these objects are formed in constant-ionization stellar winds are
Spectroscopic observations of the first helium nova V445 Puppis
At Asiago Astrophysical Observatory, we observed the peculiar, explosive object Nova (V445) Puppis 2000 during its early decline stage between January and April 2001. We acquired both high and medium
The old nova CP Puppis: a carbon nova and asynchronous polar?
Context. CP Pup (Nova Pup 1942) showed outburst and quiescent characteristics indicating a very massive white dwarf, yet the standard spectroscopic dynamical analysis assuming an accretion disk
The evolution of cataclysmic and low-mass X-ray binaries.
We present an observational study of the structure and evolution of cataclysmic and low-mass X-ray binaries, concentrating on the 124 systems for which orbital periods are known. The eruptive

On the Properties of Galactic Novae and Their Orbital Period Distribution
Using population synthesis techniques, we analyze the orbital period distribution and other ensemble properties of Galactic novae. We find that the frequency of nova outbursts in the Galactic disk
Eclipse Maps of the Accretion Disk in the Classical Nova V Persei
The surface brightness distribution in the accretion disk of V Per is reconstructed using a maximum entropy technique. The resulting brightness temperature gradient is much less steep than that from

This conference continues a long line of meetings on the general topic of cataclysmic variables (CVs) that started with the first North American Workshop in 1981. The conference held on on
The very slow nova He 3-558
The emission-line object He 3-558 has been found to be a very slow nova which rose to maximum brightness in 1948 and is probably still fading. Its spectrum and light curve are described, and a
