planetary disk造句

• This is the first infrared image where an entire inner planetary disk is clearly visible,
• If it is an outside influence, then my bet would be on something skewing the planetary disk.
• Recent observations by the Hubble Space Telescope have shown proplyds and planetary disks to be forming within the Orion Nebula.
• In 2014, using new image processing techniques on the Hubble data, researchers discovered planetary disks around these stars.
• Planetary disk formation of precursor molecules was determined, in large part, by the temperature of the solar nebula.
• Jupiter and the other solar planets represent the last generation, created as the planetary disk was dissipating and leaving more stable conditions.
• :: : : All rotation of the Sun and planets and moons must have come from the rotation of the proto-planetary disk.
• The mass of a typical proto-planetary disk is dominated by its gas, however, the presence of dust grains has a major role in its evolution.
• When the 1.8m telescope addition are complete, NPOI also will undertake additional studies of dust and proto-planetary disks, and planetary systems and their formation.
• The metallic elements : magnesium, silicon, and iron, which are the principal ingredients of rocky planets, condensed into solids at the highest temperatures of the planetary disk.
• In the Alpha Centauri system, Proxima Centauri may have influenced the planetary disk as the Alpha Centauri system was forming, enriching the area around Alpha Centauri A and B with volatile materials.
• Had it not been flung into the Solar System's farthest reaches, Planet Nine could have accreted more mass from the proto-planetary disk and developed into the core of a gas giant.
• One explanation for this . . . may be that the Carina proplyds have more massive proto-planetary disks than those in Orion, since the whole region of Carina tends to give birth to more massive stars,
• The telescope also discovered in April 2005 that Cohen-kuhi Tau / 4 had a planetary disk that was vastly younger and contained less mass than previously theorized, leading to new understandings of how planets are formed.
• The stars in this cluster were not too closely packed during their formation to disrupt planetary disk development, but were not so far apart as to prevent the seeding of Earth with radioactive elements produced by a nearby supernova.
• Even though most planetary disks can form planets, observations show that intense stellar radiation should have destroyed any proplyds that formed near the Trapezium group, if the group is as old as the low mass stars in the cluster.
• The provenance of the small fraction that is stardust ( see above ) is quite different; these refractory interstellar minerals thermally condense within stars, become a small component of interstellar matter, and therefore remain in the presolar planetary disk.
• Other discoveries made with Hubble data include proto-planetary disks ( proplyds ) in the Orion Nebula; evidence for the presence of extrasolar planets around Sun-like stars; and the optical counterparts of the still-mysterious gamma ray bursts.
• Some molecules, for example, graphite ( C ) and SiC would condense into solid grains in the planetary disk; but carbon and SiC grains found in meteorites are presolar based on their isotopic compositions, rather than from the planetary disk formation.
