Based on a linear and non-linear study of radial pulsations in the envelopes of classical novae (Schenker 1999), I discuss the results both from the point of view of pulsation theory as well as their consequences for current nova models. Starting from initially static envelope structures at various stages during the decline of a nova outburst, strong `running wave' instabilities have been found that rapidly grow into shocks. Improved analytical concepts give a new direction to the interpretation of such highly non-adiabatic radial pulsations. For direct observational confirmation a search for short period variability in the UV and soft X-ray is suggested during the very late decline phase. Speculative consequences for mass loss scenarios in novae due to these instabilities will need some more work in the future.

  1. TESS detection of periodic brightness variations during the rise of classical nova PGIR22akgylf

    astro-ph.SR 2026-06 unverdicted novelty 7.0 of 10

    Detection of a 0.1802-day periodic signal in TESS photometry of slow-rising nova PGIR22akgylf interpreted as orbital modulation from binary distortion of the envelope during common-envelope interaction.

  2. Revisiting the Classics: On the Statistics of Dust Formation in Novae

    astro-ph.HE 2025-01 conditional novelty 7.0 of 10

    Most novae (50-70%) form dust, and a redward shift in V-K color of more than 2.35 magnitudes from peak is a useful indicator of dust formation.

  3. From Light to Sound: Spectroscopic Evolution & Sonification of the flaring Nova V612 Scuti

    astro-ph.SR 2026-08 conditional novelty 5.0 of 10

    In nova V612 Sct, each optical flare corresponds to the appearance of new absorption systems at progressively higher velocities, supporting shock-powered flaring via repeated ejections.
