Nuclear Thermometers for Classical Novae [PDF]

open access: yesThe Astrophysical Journal, 2012
Classical novae are stellar explosions occurring in binary systems, consisting of a white dwarf and a main sequence companion. Thermonuclear runaways on the surface of massive white dwarfs, consisting of oxygen and neon, are believed to reach peak ...

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.

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.

The Outbursts of Classical and Recurrent Novae [PDF]

open access: yesAstronomische Nachrichten, 2011
In this review, I present our current state of knowledge regarding both Classical Nova and Recurrent Nova systems. Two particular objects (V1974 Cyg and RS Oph) are chosen to illustrate the range of phenomena that may be associated with their outbursts ...

Prospects for detectability of classical novae with INTEGRAL [PDF]

open access: yes, 2000
Classical novae are potential gamma-ray emitters, both in lines and in a continuum. Continuum emission (at energies between 20-30 and 511 keV) and line emission at 511 keV are related to positron annihilation and its Comptonization in the expanding shell;

Classical Novae at Radio Wavelengths [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2021
Abstract We present radio observations (1–40 GHz) for 36 classical novae, representing data from over five decades compiled from the literature, telescope archives, and our own programs. Our targets display a striking diversity in their optical parameters (e.g., spanning optical fading timescales, t 2 = 1–263 days), and

Classical novae with CUBES [PDF]

open access: yesExperimental Astronomy, 2022
Among the main science cases that have motivated the proposal of CUBES, a new high-resolution spectrograph for the Very Large Telescope at the European Southern Observatory, there is the study and the characterisation of the nucleosynthesis of beryllium.

Nucleosynthesis in classical novae [PDF]

open access: yesNuclear Physics A, 2001
A general review of the relevance of classical novae for the chemical evolution of the Galaxy, as well as for Galactic radioactivity is presented. A special emphasis is put on the pioneering work done by Jim Truran in this field of research. The impact of recent developments in nuclear astrophysics on nova nucleosynthesis, together with the prospects ...

The ROSAT observations of classical novae [PDF]

open access: yesInternational 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]

open access: yesProceedings 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 ...
