Detection of a Molecular Hydrogen Envelope around Nova GK Persei
The Astrophysical Journal LettersThe eruption of Nova Persei 1901 (GK Per) occurred 125 yr ago; remarkably, it still holds major surprises. Using data from the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx), we find that it has a ...

Spectroscopic monitoring of classical and recurrent novae at Asiago Observatory
, 2020 . In the course of the monitoring of spectral evolutions of classical and recurrent novae on outbursts, 11 classical novae and 2 recurrent novae (U Sco, CI Aql) were observed at Padova-Asiago Observatory in the years from 1990 to 2001.

Na-22 decay gamma rays from classical novae [PDF]
, 1993 NASA Grant NAG 5-1565 has provided support for a program of theoretical research in nuclear astrophysics and related areas, focusing upon the possibility of detecting gamma rays from nearby novae.

The Astrophysical JournalRecurrent nova (RN) T Pyxidis (T Pyx) has a complex history of mass accreting onto and ejection from the white dwarf, with a classical nova eruption around 1866 kick-starting an RN-phase with six RN eruptions from 1890–2011. T Pyx is a primary progenitor

The Astrophysical JournalThe 135 classical novae that we have discovered in M87 with two Hubble Space Telescope imaging surveys appear to be strongly concentrated along that galaxy’s jet.

Fermi-LAT detections of the classical novae V1723 Sco and V6598 Sgr in a multi-wavelength context
Astronomy & AstrophysicsContext. Numerous classical novae have been observed to emit γ-rays (E > 100 MeV) detected by the Fermi-LAT. The prevailing hypothesis attributes this emission to the interaction of accelerated particles within shocks in the nova ejecta.

Long-Term Photometry of Very Slow Novae
Open Astronomy, 2003 Long-term photographic, photoelectric and recent CCD photometry of the classical nova V723 Cas and symbiotic novae V1329 Cyg, PU Vul, V1016 Cyg and HM Sge were used to find their orbital periods.

A Full Cycle in the Evolution of a Classical Nova [PDF]
International Astronomical Union Colloquium, 1987 AbstractA classical nova model was evolved through a complete cycle, i.e. accretion leading to outburst, mass loss and again accretion, ending in another outburst, by means of an implicit Lagrangian hydrodynamic code, which included diffusion (concentration, pressure and thermal terms), as well as an extensive nuclear reactions network between 28 ...

Acta Polytechnica CTU Proceedings, 2015 In recent years, recurrent nova eruptions are often observed very intensely in wide range of wavelengths from radio to optical to X-rays. Here I present selected highlights from recent multi-wavelength observations. The enigma of T Pyx is at the heart of

A Demarcation Criterion for Hydrogen Burning of Millinovae
The Astrophysical JournalMillinovae are a new class of transient supersoft X-ray sources with no clear signature of mass ejection. They show similar triangle shapes of V / I band light curves with 1000 times fainter peaks than typical classical novae. Maccarone et al.
