dust disk造句

• Spitzer's heat-sensitive optics detect the dust disks.
• The spectral signature of olivine has been seen in the dust disks around young stars.
• In 1998 the discovery of a possible dust disk around 55 Cancri A was announced.
• Dust disks have now been found around more than 15 % of nearby sunlike stars.
• SIRTF will identify recently formed or forming solar systems by finding dust disks around nearby stars.
• New discoveries included a dust disk around Vega and the first images of the Milky Way core.
• It allowed them to examine the infrared radiation reflected by the dust disk without interference from the star.
• Upsilon Andromedae does not appear to have a circumstellar dust disk similar to the Kuiper belt in the Solar System.
• This link shows an HST image of a dust disk surrounding a bright star with the star hidden by the coronagraph.
• American astrophysicist Alice C . Quillen and her student Stephen Thorndike performed computer simulations of the structure of the dust disk around Epsilon Eridani.
• The Hubble Space Telescope is capable of observing dust disks with its NICMOS ( Near Infrared Camera and Multi-Object Spectrometer ) instrument.
• Another picture taken by NICMOS as part of the same series of images of stars in search of dust disks also provides evidence for a planet.
• The structure of the belts and the dust disk suggests that more than two planets in the Epsilon Eridani system are needed to maintain this configuration.
• But Chen said that the evidence was insufficient to determine if the dust disk was a remnant of planet formation or a place where planets could form.
• The age of the star is not precisely known; the ELODIE spectrograph suggested 0.8 Gyr and found it to have a young dust disk.
• _Extraterrestrial life : Found dust disks rotating around nearby stars, suggesting that new planets are being formed _ and that life presumably exists elsewhere in the universe.
• Dermott was among the members of a joint UF-Harvard team that last year announced the discovery of the dust disk around HR 4796 and its companion star.
• These observations indicated that the planet has a mass 1.5 times that of Jupiter and shares the same plane as the outer dust disk observed around the star.
• Another interesting and mildly surprising aspect of the discovery is that HR4796 is a member of a binary system; it has a faint companion star far beyond the dust disk.
• The infrared camera allows the Hubble to observe the most distant reaches of the universe as well as peer into the dust disks that surround prospective planet-forming star systems.
