Astronomers Discover Unusual X-Ray Oscillations From a Black Hole 100 Million Light-Years Away
According to the research shared at the 245th meeting of the American Astronomical Society in National Harbor, Maryland, the observed X-ray oscillations are believed to originate from a compact white dwarf orbiting close to the black hole's event horizon.
Potentially habitable exoplanets are so incredibly common that astronomers have started to consider more unusual situations ...
It's the definition of "no pain, no gain." The rapid spin of this white dwarf, that is vampirically taking stellar matter away from a companion star, could be explained by its shrinking radius.
Scientists have observed X-rays emanating from a white dwarf orbiting a supermassive black hole in a galaxy near the Milky Way. The study notes the stability of the dwarf's orbit, despite its ...
In this artist’s concept, matter is stripped from a white dwarf (sphere at lower right) orbiting within the innermost accretion disk surrounding 1ES 1927+654’s supermassive black hole. Astronomers ...

In a recent study, an Italian astronomer has investigated the nature of a binary system known as HD 49798/RX J0648.0–4418.
The Hubble Space Telescope recently captured a snapshot of a rare supernova that sits in the Gemini constellation, about 650 ...
