Astronomers use stellar eclipses to study the atmosphere of accretion disks around compact stars. SRON-researchers observed this method on a low-mass X-ray binary. They find a thicker atmosphere than predicted and distinguish ...

A stellar mass black hole is a compact object with a mass greater than three solar masses. It is so dense and has such a powerful force of attraction that not even light can escape from it. They cannot be observed directly, ...

Cataclysmic variable stars (CVs) are white dwarf stars that are accreting from an orbiting, low mass binary companion star. The accretion is facilitated by the proximity of the stars; typical orbital periods range from about ...
