Scientists observed a white dwarf star, LSPM J0207+3331, actively consuming planetary debris, including a rocky body likely similar to Earth, revealing ongoing planetary system dynamics billions of years after star death and challenging traditional views of stellar remnants.
Astronomers have observed a 'zombie' white dwarf star, LSPM J0207+3331, actively devouring remnants of a rocky planet after three billion years, challenging previous assumptions about the dormancy of such stars and suggesting planetary systems can remain unstable for eons.
Astronomers have observed a white dwarf star, LSPM J0207+3331, actively tearing apart a planetary body, revealing recent accretion of debris rich in Earth-like elements, challenging current understanding of planetary system evolution and suggesting ongoing dynamical processes long after the star's death.
Astronomers using ESO's VLT have discovered a scar on the surface of a white dwarf star, WD 0816-310, caused by ingesting planetary debris, indicating the role of the star's magnetic field in this process. The scar is a concentration of metals from a planetary fragment, possibly as large as Vesta, and is located on one of the star's magnetic poles. This unique discovery sheds light on the dynamics of planetary systems even after the death of a star and provides insights into the bulk composition of exoplanets.
Astronomers using the Very Large Telescope have discovered a scar on the surface of a white dwarf star, WD 0816-310, caused by the star ingesting planetary debris. This unique signature, resulting from the cannibalization of planets and asteroids, is the first of its kind seen on a white dwarf. The scar is concentrated in a specific area and is held in place by the star's magnetic field. This discovery sheds light on the dynamics of planetary systems after the death of their host stars and demonstrates the power of the VLT instrument FORS2 in studying astronomical objects.
Astronomers using the Very Large Telescope have observed a scar on the surface of a white dwarf, indicating ingestion of planetary debris, shedding light on the behavior of "cannibal" stars. The scar, made up of metal elements from a planetary fragment or asteroid, was found to be prevented from mixing with the rest of the star's surface by its magnetic field. This discovery provides insight into the fate of our own solar system, as our sun is expected to become a white dwarf in about 5 billion years.
The James Webb Space Telescope has captured stunning images of three nested, dusty debris belts orbiting the young star Fomalhaut. The inner belts are believed to have been carved out by the gravitational forces of unseen planets. The belts extend out to 14 billion miles from the star and provide new insights into the formation of planetary systems.
