Using the TIGRE telescope, astronomers have conducted spectroscopic observations of recently discovered nova known as V659 Sct during multiple phases of its outburst. Results of this observational campaign, presented in a ...
A nova, or stella nova, the Latin word for "new star," is an explosion on the surface of a star that can produce enough energy to increase the star's brightness by millions of times. Sometimes a nova, which occur in stars ...

Astronomers have conducted observations of a symbiotic star in the Large Magellanic Cloud (LMC), known as LMC S154, which provide new insights about the nature of this object. Results of these observations, presented in a ...
A San Diego State University astrophysicist has helped discover evidence of a gigantic remnant surrounding an exploding star—a shell of material so huge, it must have been erupting on a regular basis for millions of years.

An international team of researchers led by Luca Izzo of the Institute of Astrophysics of Andalusia, Spain, has conducted high-resolution spectroscopic observations of the fast nova ASASSN-16kt. The study, which resulted ...
Brazilian astronomers have performed photometric observations of the dwarf nova V2051 Oph during its quiescent period, which revealed important insights into the nature of this object. The results were presented in a paper ...
In a typical year, there are around 50 novae, nuclear explosions on the surface of white dwarf stars, in our galaxy. Some of these explosions are so bright and powerful, they exceed the scale of scientific explanation.
