Russian astronomers have carried out spectroscopic and photometric observations of a cataclysmic variable designated Gaia ...

The Einstein Probe was launched in January 2024 to study the high-energy universe, and among its instruments is its ...

ABSTRACT We report spectroscopy of the newly discovered SU Ursae Majoris dwarf nova identified with the X‐ray source RXS J053234.9+624755. Radial velocities of the Hα emission line in the quiescent ...

For instance, the dwarf nova PNV J00444033+4113068 exhibited early superhumps with a remarkable amplitude of 0.7 magnitudes, the largest recorded for this type of star. This phenomenon is ...

Lobster-eye satellite Einstein Probe captured the X-ray flash from a very elusive celestial pair. The discovery opens a new ...

Publications of the Astronomical Society... ABSTRACT Stunted outbursts have been reported in old novae and nova‐like cataclysmic variables by Honeycutt, Robertson, and Turner. These 0.4–1 mag ...

Astrophysicists have unearthed a surprising diversity in the ways in which white dwarf stars explode in deep space after ...

Ancient ‘white dwarf’ stars explode and die in more ways than was thought, and observing these violent cosmic deaths could ...

A flash of powerful X-ray light coming from a nova explosion on a white dwarf star has caught the attention of astronomers using the Chinese–European Einstein Probe. This nova is especially ...

This can trigger a supernova in two ways. Firstly, the collision itself can create a larger white dwarf and a type Ia supernova. Alternatively, the stellar remnant this creates can birth a ...
