Astronomers have for the first time found gas-phase ammonia in a protoplanetary disc
... bodies followed by a sufficiently high collision rate to release the volatiles. On the other hand, in the colder outer protoplanetary disc, the synthesis of ammonia in the gas phase relies on ion-molecule chemistry. If the water and ammonia emission...

Protoplanetary disc shares similarities with our own Solar System say researchers
...systems beyond our own Solar System formed. by performing full spectral scans of young stellar objects embedded in protoplanetary discs. The young stellar object in question is HD 142527, a Herbig Ae/Be star located 145 parsecs away. Herbig stars are...

Novel technique helps discover three protoplanets around newborn star
... massive object is on hand to create such disturbances. “We looked at the localised, small-scale motion of gas in the star’s protoplanetary disc. This entirely new approach could uncover some of the youngest planets in our galaxy, all thanks to the...

Baby planet in dusty disc finally caught on camera
...known, young planetary systems and their circumstellar discs to study the initial conditions of planetary .... “We needed to observe a planet in a young star’s disc to really understand the processes behind planet formation.” Thomas Henning, director...

Researchers show how water content in protoplanetary discs can affect planet formation
... suggests that planetary cores must form within a few million years, the same time as a typical lifetime of protoplanetary disc, in order to attract a gaseous envelope. Past studies have focused on the abundances of oxygen and carbon in hot Jupiters...
