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 ...

Connecting Recurrent Novae to [Some] Type Ia Supernovae [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractIn this review, I summarize the observational attempts made so far to unveil the nature of the progenitor system(s) of Type Ia supernovae. In particular, I focus on the most recent developments that followed the claimed detection of circumstellar material around a few events, and on the link this possibly establishes with recurrent novae.

Lepto-hadronic Interpretation of 2021 RS Ophiuchi Nova Outburst
The Astrophysical Journal, 2023 Very-high-energy (VHE; 100 GeV < E ≤ 100 TeV) and high-energy (HE; 100 MeV < E ≤ 100 GeV) gamma rays were observed from the symbiotic recurrent nova RS Ophiuchi (RS Oph) during its outburst in 2021 August by various observatories, such as the High Energy

DUAL MOBILITY CUP CEMENTED INTO POROUS TRABECULAR METAL SHELL DURING REVISION TOTAL HIP ARTHROPLASTY [PDF]
Journal of IMAB, 2023 Revision total hip arthroplasty (RTHA) is a challenging procedure when we speak about acetabular defects and recurrent instability. There are multiple reasons like the number of previous revisions, implant position, bone quality, patient characteristics ...

International Astronomical Union Colloquium, 1988 AbstractAn examination of the existing observational material on all the objects classified as recurrent novae, reveals that only T Pyx, U Sco, T CrB and RS Oph deserve such a classification. We review the properties of outbursts powered by thermonuclear runaways and accretion events and determine their observational consequences.

Recurrence of Nova Explosions [PDF]
International Astronomical Union Colloquium, 1979 It has been shown by many computations that a nova explosion is triggered by mass accretion onto a white dwarf in a close binary system. Such nova explosions will recur many times in the following way. When a certain amount of hydrogen-rich gas has been accreted on the white dwarf, a hydrogen-shell flash is ignited.

A pre-outburst signal in the long-term optical light curve of the recurrent nova RS Ophiuchi [PDF]
, 2011 Recurrent novae are binary stars in which a white dwarf accretes matter from a less evolved companion, either a red giant or a main-sequence star. They have dramatic optical brightenings of around 5–6 mag in V in less than a day, several times a century.

Symbiotic Star T CrB as an Extreme SU UMa–type Dwarf Nova
The Astrophysical Journal Letters, 2023 T CrB is a symbiotic recurrent nova that exhibits quiescent and active phases between its classical nova eruptions. The statistical properties of these active phases have been poorly studied thus far. Because of that their nature remained unknown.
