A Century of Novae in the Large Magellanic Cloud

open access: yesThe Astrophysical Journal Supplement Series
A comprehensive study of novae in the Large Magellanic Cloud (LMC) is presented. A total of 66 nova eruptions have been reported in the LMC over the past century (1926–2025).

Identification of a Superbright Nova in Our Galaxy: Revisiting the Light-curve Analyses of the Candidate Novae CP Lac, CP Pup, V838 Her, V597 Pup, V5583 Sgr, and V5589 Sgr

open access: yesThe Astrophysical Journal
The two very fast novae in our Galaxy, V1500 Cyg and V1674 Her, have reached the absolute V magnitude of ${M}_{V,{\rm{\max }}}\approx -10.4$ . These brightest novae are identified as superbright novae.

Recurrent novae [PDF]

open access: yes, 1993
Recurrent novae seem to be a rather inhomogeneous group: T CrB is a binary with a M III companion; U Sco probably has a late dwarf as companion. Three are fast novae; two are slow novae. Some of them appear to have normal chemical composition; others may

Multiwavelength study of the pre-eruption dip in the recurrent nova T Coronae Borealis preceding imminent nova eruption

open access: yesAstronomy & Astrophysics
We present a multiwavelength study of the symbiotic recurrent nova T Coronae Borealis (T CrB), using the Swift Burst Alert Telescope (BAT)/ X-Ray Telescope (XRT) / UltraViolet Optical Telescope (UVOT) and American Association of Variable Stars Observers (

The Contribution of a Community Event to Expert Work: An Activity Theoretical Perspective

open access: yesOutlines, 2004
Becoming an expert in any knowledge domain takes time and a great deal of learning, both theoretical and experiential.  The individual’s knowledge is often supplemented through knowledge exchanges with other experts.

Fermi-LAT detections of the classical novae V1723 Sco and V6598 Sgr in a multi-wavelength context

open access: yesAstronomy & Astrophysics
Context. 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.

Prehistoric Novae [PDF]

open access: yes
Neolithic flint tools were discovered in three sectors in Novae (II, IV, and XII): polished axes, scrapers, and blades. An arched beaked point was discovered at the Ostrite Mogili site, east of Novae.

The Long-Term Spectroscopic Misadventures of AG Dra with a Nod Toward V407 Cyg: Degenerates Behaving Badly

open access: yesOpen Astronomy, 2012
We present some results of an ongoing study of the long-term spectroscopic variations of AG Dra, a prototypical eruptive symbiotic system. We discuss the effects of the environment and orbital modulation in this system and some of the physical processes ...
