Add a definition Delivery rates are more efficient toprotoplanetarydiscs, as the solid grains effectively sputter the incoming material in hypervelocity collisions. From theCambridge English Corpus The reason for this revisitation lies in the fact that complex organic matter resembling a petroleum fraction may exist in certainprotoplanetarynebulae. From theCambridge English Corpus Derived core masses and observed short lifetimes ofprotoplanetarydisks strongly constrain conditions for forming gas giant planets. From theCambridge English Corpus A disc of scatteredprotoplanetaryand planetesimal material is building up in external orbits. From theCambridge English Corpus The structure and chemistry ofprotoplanetarydisks depend strongly on the nature of the central star around which they have formed. From theCambridge English Corpus The resulting spectrum is able to match the emission spectrum of aprotoplanetarynebula. From theCambridge English Corpus A gravitationally unstableprotoplanetarydisk forms giant gaseous protoplanets within about 1000 years, while dust grains coagulate and sediment to their centers, forming solid cores. From theCambridge English Corpus These include the 21 and 30 mm emission features, and the extended red emission observed inprotoplanetarynebulae and planetary nebulae. From theCambridge English Corpus The grains from which meteorites initially aggregated were interstellar silicates, processed through a molecular cloud prior to accretion in theprotoplanetarydisc. From theCambridge English Corpus In the followingprotoplanetarynebulae stage, emission features corresponding to stretching and bending modes of aliphatic compounds are detected. From theCambridge English Corpus The global modelling of dust and gas evolution inprotoplanetarydiscs should follow. From theCambridge English Corpus In this introduction, we have started from the observation that petroleum fractions may exist in certainprotoplanetarynebulae. From theCambridge English Corpus The protoplanet evolves under the gravitational interaction of the central star and theprotoplanetarydisc. From theCambridge English Corpus Thus, these petroleum fractions can be used as model for the matter present in the interstellar medium or in theprotoplanetarynebulae. From theCambridge English Corpus Dusty plasmas, perhaps the fastest growing area in plasma physics, might also be of extreme importance for the theory ofprotoplanetarydiscs. From theCambridge English Corpus In other words, it appears that the organic and carbonaceous matter present in theprotoplanetarynebulae should be closer in composition to that found in carbonaceous chondrites. From theCambridge English Corpus The main aim of our work was to investigate the evolution of the planet's orbit due to the torque exerted on it by the truncatedprotoplanetarydisc. From theCambridge English Corpus We have also addressed our discussion to the possible formation of petroleum fractions or petroleum-like organic matter, which could exist both in the interstellar medium and in theprotoplanetarynebulae.
