An international team of astronomers has inspected a low-mass X-ray binary system known as GX 339-4. Results of the study, reported in a paper published Nov. 21 on the pre-print server arXiv, shed more light on the high-frequency ...
OJ 287 is recognized as a binary black hole system with a slowly spiraling orbit caused by loss of energy to gravitational radiation. This energy loss was already confirmed in 2008. Subsequent measurements have confirmed ...

Using various spacecraft and ground-based observatories, an international team of astronomers has performed a multi-wavelength study of a cataclysmic variable system known as Swift J0503.7-2819. Results of the study, published ...
Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), Indian astronomers have observed an eclipsing X-ray binary system known as 4U 1538-522. Results of the observational campaign, published September 26 in the Monthly ...
Astronomers from the Binary Systems of South and North (BSN) project have conducted photometric observations of a distant binary star known as V0610 Virgo. Results of the observation campaign, published Sept. 23 in a research ...
Gamma-ray bursts (GRBs) are some of the most violent events in the universe. Some have a power output equivalent to all of the other stars in the observable universe, at least in the spectrum of gamma rays. But we know very ...
