  • celestial
  • However, the main practical problem existing in the autonomous celestial navigation of spacecraft on a gravity assist trajectory is that the accuracy of trajectory model is not enough to be used in the real navigation sometimes, which may introduce large estimation error and even cause filter divergence. (hindawi.com)
  • In deep space missions, a gravity assist trajectory is often used, which uses the gravity of a planet (or other celestial body) to alter the path and speed of a spacecraft. (hindawi.com)

  • Michell's idea for calculating the number of such "invisible" stars anticipated 20th century astronomers' work: he suggested that since a certain proportion of double-star systems might be expected to contain at least one "dark" star, we could search for and catalogue as many double-star systems as possible, and identify cases where only a single circling star was visible. (wikipedia.org)
  • refers

  • however
  • It is unprecedented, however, to find such a massive star and witness its death. (activistchat.com)
  • However, Michell cited Newton as saying that blue light was less energetic than red (Newton thought that more massive particles were associated with bigger wavelengths), so Michell's predicted spectral shifts were in the wrong direction. (wikipedia.org)
  • However the case of an Earth-Moon satellite can be simplified to four interactions, because although the three objects gravitationally all pull on each other, the effect of the spacecraft's gravity upon the motion of the vastly more massive Earth and Moon is practically non-existent. (wikipedia.org)

  • According to the team's analysis, the data ruled out the possibility that Sgr A* contains a cluster of dark stellar objects or a mass of degenerate fermions, strengthening the evidence for a massive black hole. (wikipedia.org)
  • Reinhard Genzel, team leader of the research, said the study has delivered "what is now considered to be the best empirical evidence that super-massive black holes do really exist. (wikipedia.org)
  • This is not the case for the 5D black holes with only one rotation, e.g. black ring. (springer.com)
  • As an example we calculate the associated central charge for the Myers-Perry black hole [ 15 ] and show the agreement with known results in this case. (springer.com)
  • effect
  • The effect is small, such that (in the case of strong lensing) even a galaxy with a mass more than 100 billion times that of the Sun will produce multiple images separated by only a few arcseconds. (wikipedia.org)
  • This effect can be reduced by making the gravity well shallower (i.e. by choosing a smaller scaling factor for the Φ axis). (wikipedia.org)

  • That means the star that exploded might have been as massive as a star can get, about 150 times that of our sun. (activistchat.com)
  • This provides strong evidence that SN 2006gy was, in fact, the death of an extremely massive star," said Dave Pooley of the University of California at Berkeley, who led the Chandra observations. (activistchat.com)
  • Under some conditions, the core of a massive star produces so much gamma ray radiation that some of the energy from the radiation converts into particle and anti-particle pairs. (activistchat.com)
