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.

Recurrent Nova IM Normae [PDF]

open access: yesAstronomy & Astrophysics, 2002
We detected the second historical outburst of the 1920 nova IM Nor. Accurate astrometry of the outbursting object revealed the true quiescent counterpart having a magnitude of R=17.0 mag and B=18.0 mag.

Shortest Recurrence Periods of Forced Novae [PDF]

open access: yesThe Astrophysical Journal, 2016
We revisit hydrogen shell burning on white dwarfs (WDs) with higher mass accretion rates than the stability limit, \dot M_stable, above which hydrogen burning is stable. Novae occur with mass accretion rates below the limit.

ORBITAL PERIODS FOR THREE RECURRENT NOVAE [PDF]

open access: bronzeThe Astrophysical Journal, 2009
I report on the discovery of the orbital periods of three recurrent novae in our galaxy. V745 Sco has an orbital period of 510+-20 days with ellipsoidal modulations, based on SMARTS photometry from 2004-2008. V3890 Sgr has an orbital period of 519.7+-0.3 days with ellipsoidal modulations and a shallow eclipse, based primarily on SMARTS and AAVSO ...

Recurrent Novae [PDF]

open access: bronzeInternational Astronomical Union Colloquium, 1990
AbstractThermonuclear models of recurrent novae demand white dwarf accretors near the Chandrasekhar mass. In this case, the known recurrent novae should possess classical counterparts bearing the same structural parameters and space distribution, save for having only marginally less massive white dwarfs.

Association between Recurrent Novae and Nova Super-Remnants [PDF]

open access: greenProceedings of The Golden Age of Cataclysmic Variables and Related Objects - VI — PoS(GOLDEN2023)
Nova super-remnants (NSRs) are substantially extended structures (up to ~130 parsecs across) encompassing recurrent novae. NSRs grow as a result of frequent nova eruptions transporting vast quantities of the locally surrounding interstellar medium away from the binary system over many millennia into a thin high-density shell, as the central white dwarf

CIRCUMSTELLAR SHELL FORMATION IN SYMBIOTIC RECURRENT NOVAE [PDF]

open access: bronzeThe Astrophysical Journal, 2012
We present models of spherically symmetric recurrent nova shells interacting with circumstellar material in a symbiotic system composed of a red giant expelling a wind, and a white dwarf accreting from this material. Recurrent nova eruptions periodically eject material at high velocities ($\gtrsim 10^3$ km/s) into the red giant wind profile, creating a

The nature of recurrent novae [PDF]

open access: yesAstrophysics and Space Science, 1987
AbstractThe observational properties and outburst histories of each member of the small class of recurrent novae are reviewed, with the objective of identifying the outburst mechanisms for these systems. Examples are found of both accretion-powered outbursts (T CrB and RS Oph) and thermonuclear-powered outbursts (T Pyx and U Sco).
