The ROSAT observations of classical novae [PDF]
International Astronomical Union Colloquium, 1996 We observed a number of classical and recurrent novae in the Galaxy and the LMC with the ROSAT X-ray telescope and searched the archival data for other serendipitous observations. Preliminary results show that only 9 out of 37 observed objects were bright enough in X-rays to be detected with ROSAT, either in outburst or at quiescence.Three basic ...

Classical and Recurrent Nova Models [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractRemarkable progress in the understanding of nova outbursts has been achieved through combined efforts in photometry, spectroscopy and numerical simulations. According to the thermonuclear runaway model, novae are powered by thermonuclear explosions in the hydrogen-rich envelopes transferred from a low-mass stellar companion onto a close white ...

Gap Transients Interacting with Circumstellar Medium
Universe, 2022 In the last 20 years, modern wide-field surveys discovered a new class of peculiar transients, which lie in the luminosity gap between standard supernovae and classical novae. These transients are often called “intermediate luminosity optical transients”

A Review of the Classical Nova Outburst [PDF]
International Astronomical Union Colloquium, 1987 AbstractWe review the recent observational and theoretical studies of the nova outburst. The observational studies have not only identified a new class of novae but theoretical simulations of this class have been found to be in excellent agreement with the observations.

Theory of Nova Outbursts and Type Ia Supernovae
Acta Polytechnica CTU Proceedings, 2015 We briefly review the current theoretical understanding of the light curves of novae. These curves exhibit a homologous nature, dubbed the universal decline law, and when time-normalized, they almost follow a single curve independently of the white dwarf

Ultraviolet and X-ray Light-Curves of Novae Observed by the Neil Gehrels Swift Observatory
Universe, 2022 With rapid response capabilities, and a daily planning of its observing schedule, the Neil Gehrels Swift Observatory is ideal for monitoring transient and variable sources.

AT Cnc: A SECOND DWARF NOVA WITH A CLASSICAL NOVA SHELL [PDF]
The Astrophysical Journal, 2012 We are systematically surveying all known and suspected Z Cam-type dwarf novae for classical nova shells. This survey is motivated by the discovery of the largest known classical nova shell, which surrounds the archetypal dwarf nova Z Camelopardalis.

Theoretical Light-curve Models of the Symbiotic Nova CN Cha—Optical Flat Peak for 3 Yr
The Astrophysical Journal, 2023 CN Cha is a slow symbiotic nova characterized by a 3 yr long optical flat peak followed by a rapid decline. We present theoretical light curves for CN Cha, based on hydrostatic approximation, and estimate the white-dwarf (WD) mass to be ∼0.6 M _☉ for a ...

IDENTIFYING AND QUANTIFYING RECURRENT NOVAE MASQUERADING AS CLASSICAL NOVAE [PDF]
The Astrophysical Journal, 2014 Recurrent novae (RNe) are cataclysmic variables with two or more nova eruptions within a century. Classical novae (CNe) are similar systems with only one such eruption. Many of the so-called 'CNe' are actually RNe for which only one eruption has been discovered.
