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 ...

Using the AstroSat satellite, astronomers have investigated a low-mass X-ray binary (LMXB) known as 4U 1323-62, reporting the detection of thermonuclear X-ray bursts and dips from the source. The discovery was presented in ...
An international team of astrophysicists led by Australian Professor Matthew Bailes, from the ARC Centre of Excellence of Gravitational Wave Discovery (OzGrav), has shown exciting new evidence for 'frame-dragging'—how the ...

Russian astronomer Valery Kozhevnikov has conducted photometric observations of the cataclysmic variable (CV) IPHAS J013031.89+622132.3 (J0130 for short), finding that the object exhibits deep eclipses. The discovery, presented ...
Researchers using ESO's Very Large Telescope have, for the first time, found evidence of a giant planet associated with a white dwarf star. The planet orbits the hot white dwarf, the remnant of a Sun-like star, at close range, ...

Cataclysmic variables (CVs) are binary star systems consisting of a white dwarf and a normal star companion. They irregularly increase in brightness by a large factor, then drop back down to a quiescent state. Although over ...
Earth-like planets may be common in the universe, a new UCLA study implies. The team of astrophysicists and geochemists presents new evidence that the Earth is not unique. The study was published in the journal Science on ...

Using ESA's XMM-Newton spacecraft, an international team of astronomers has discovered a new, very young high-mass X-ray binary (HMXB) in the Large Magellanic Cloud (LMC). The newly found HMXB turns out to be associated with ...
Astronomers have investigated a compact binary radio pulsar system known as PSR J0453+1559, with the aim of shedding more light on its mysterious nature. The new study, published September 26 on arXiv.org, challenges previous ...
