We discuss the chemical pre-conditions for planet formation, in terms of gas and ice abundances in a protoplanetary disk, as function of time and position, and the resulting chemical composition and ...

Planet traps are necessary to prevent forming planets from falling onto their host star by type I migration. Surface mass density and temperature gradient irregularities favor the apparition of traps ...

A Sun-type star situated nearly 3,000 light-years from Earth has provided astronomers with a unique opportunity to observe an ...

Protoplanetary disks are the birthplaces of planets, but few discoveries have stretched scientific expectations like IRAS ...

When a star is young, it is often still surrounded by a primordial rotating disk of gas and dust, from which planets can form. Astronomers like to find such disks because they might be able to catch ...

Southwest Research Institute has collaborated with Yale University to summarize the scientific community's notable progress in advancing the understanding of the formation and evolution of the inner ...

A team of researchers at the Leiden Observatory in the Netherlands recently published the first detection of dimethyl ether in a planet-forming disc in Astronomy & Astrophysics. Dimethyl ether is the ...

What specific processes are responsible for planetary formation and evolution? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of ...

"The extraordinary results are an essential step toward understanding the initial conditions that lead to the formation of Earth-like planets." When you purchase through links on our site, we may earn ...

Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months.
