The UBV Color Evolution of Classical and Symbiotic Novae [PDF]

open access: yesActa Polytechnica CTU Proceedings, 2015
We identified a general course of classical nova outbursts in the B − V vs. U − B diagram. It has been reported that novae show spectra similar to A–F supergiants near optical light maximum.

NUCLEAR MIXING METERS FOR CLASSICAL NOVAE [PDF]

open access: yesThe Astrophysical Journal, 2013
Classical novae are caused by mass transfer episodes from a main sequence star onto a white dwarf via Roche lobe overflow. This material forms an accretion disk around the white dwarf. Ultimately, a fraction of this material spirals in and piles up on the white dwarf surface under electron-degenerate conditions. The subsequently occurring thermonuclear

Gap Transients Interacting with Circumstellar Medium

open access: yesUniverse, 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]

open access: yesInternational 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

open access: yesActa 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

open access: yesUniverse, 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]

open access: yesThe 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

open access: yesThe 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]

open access: yesThe 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.
