Researchers set out to study the protoplanetary disk around a star known as HD 100546, and as sometimes happens in scientific inquiry, it was by "chance" that they stumbled upon the formation of the planet orbiting this star.
A large gap discovered in the protoplanetary disk of a Sun-like star may have resulted from the birth of multiple planets, an international team of researchers claim in a new study.
Two University of Hawai'i at MÄnoa astronomers have found a binary star-disk system in which each star is surrounded by the kind of dust disk that is frequently the precursor of a planetary system.
What superficially resembles a giant moth floating in space is giving astronomers new insight into the formation and evolution of planetary systems.
Astronomers using the Hubble Space Telescope and W. M. Keck Observatory have found a lopsided debris disk around a young star known as HD 15115. As seen from Earth, the edge-on disk resembles a needle sticking out from the star.
A close look at the protoplanetary disk around a young star by two teams of astronomers using the Subaru telescope on Mauna Kea has led to the unexpected discovery of two banana-shaped arcs facing each other.
NASA's Hubble Space Telescope has revealed not one but two dust disks circling the nearby star Beta Pictoris. This is evidence for the possibility of at least one Jupiter-size planet orbiting the star.
These two bright debris disks of ice and dust appear to be the equivalent of our own solar system's Kuiper Belt, a ring of icy rocks outside the orbit of Neptune and the source of short-period comets.
