Classical Novae at Radio Wavelengths [PDF]
The Astrophysical Journal Supplement Series, 2021 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.

Nuclear Thermometers for Classical Novae [PDF]
The 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 ...

Mixing fraction in classical novae [PDF]
Astronomy & Astrophysics, 2022 Context. Classical novae are powered by thermonuclear runaways occurring on the surface of accreting white dwarfs (WDs). In the observations, the enrichments of heavy elements in nova ejecta have been detected, indicating a mixing process between the ...

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.

123–321 models of classical novae [PDF]
Astronomy & Astrophysics, 2019 Context. High-resolution spectroscopy has revealed large concentrations of CNO and sometimes other intermediate-mass elements (e.g., Ne, Na, Mg, or Al, for ONe novae) in the shells ejected during nova outbursts, suggesting that the solar composition ...

Nuclear Mixing Meters for Classical Novae [PDF]
The 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.

Classical novae with CUBES [PDF]
Experimental 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.

A Light-curve Analysis of the X-Ray Flash First Observed in Classical Novae [PDF]
Astrophysical Journal Letters, 2022 An X-ray flash, expected in a very early phase of a nova outburst, was at last detected with the SRG/eROSITA in the classical nova YZ Reticuli 2020. The observed flash timescale, luminosity, and blackbody temperature substantially constrain the nova ...

Hydrogen Burning of 29Si and Its Impact on Presolar Stardust Grains from Classical Novae [PDF]
Astrophysical Journal, 2022 Presolar stardust grains found in primitive meteorites are believed to retain the isotopic composition of stellar outflows at the time of grain condensation.

A search for cool molecular gas in GK Persei and other classical novae [PDF]
Astronomy & Astrophysics, 2022 Detecting molecular line emission from classical nova remnants has the potential to reveal information on the composition of the ejecta, in particular accurate isotopic ratios in the matter processed by a thermonuclear runaway.
