We survey our understanding of classical novae—nonterminal, thermonuclear eruptions on
the surfaces of white dwarfs in binary systems. The recent and unexpected discovery of GeV …

Supermassive black holes grow at the centre of galaxies in consonance with them. In this
Review Article, we discuss the mass-feeding mechanisms that lead to this growth in active …

Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of
the last, mass-losing phases of 90% of stars initially more massive than the Sun. Here we …

Context. Evolved low-mass stars lose a significant fraction of their mass through stellar
winds. While the overall morphology of the stellar wind structure during the asymptotic giant …

We present the evolution of the optical spectra of the 2021 outburst of RS Ophiuchi (RS Oph)
over about a month after the outburst. The spectral evolution is similar to the previous …

Red novae are optical transients erupting at luminosities typically higher than those of
classical novae. Their outbursts are believed to be caused by stellar mergers. We present …

We present the results of the investigation of the nova V1674 Her (2021), recognized as the
swiftest classical nova, with t 2∼ 0.90 d. The distance to the nova is estimated to be 4.97 …

Context. V838 Mon erupted in 2002, quickly becoming the prototype of a new type of stellar
eruption known today as the (luminous) red nova. Red nova outbursts are thought to be …

We present a state‐of‐the‐art report on visualization in astrophysics. We survey
representative papers from both astrophysics and visualization and provide a taxonomy of …

The morphology of the ejected shell of the He/N Nova Monocerotis 2012 outburst was
studied in detail. Synthetic line profile spectra were compared to the [O iii] 4959, 5007 Å …
