Study of ‘polluted’ white dwarfs finds that stars and planets grow together

Astronomers have discovered evidence that planetary formation can begin very quickly after the birth of a star. This incredible insight into the histories of planetary systems comes from white dwarfs, the dying remnants of the cores of stars like our Sun, rather than from...

Study explores the properties of a unique intermediate polar

Indian astronomers conducted a broadband X-ray analysis of a unique intermediate polar known as Paloma using data from ESA's XMM-Newton satellite and NASA's NuSTAR space observatory. The study's findings, which were published on arXiv.org on June 17, shed more light on the properties of...

Researchers explain formation of millisecond pulsars with long orbital periods

Chinese Academy of Sciences researchers have explained the formation of millisecond pulsars (MSPs) with long orbital periods by accretion-induced collapse of white dwarfs. The study was published in Monthly Notices of the Royal Astronomical Society. Neutron star (NS) systems are generally believed to be formed via...

Mapping the movement of white dwarfs of the Milky Way

White dwarfs were once normal stars similar to the sun. Then they collapsed after exhausting all their fuel. These interstellar remnants have historically been difficult to study. But Lund University in Sweden scientists reveal new information about the movement patterns of these puzzling stars. White...
