So far, one planet has been studied by this method. ...

In ancient times the solar system was thought to be the whole Universe, so the study of planetary motions was cosmology. ... The planets other than the Moon and Sun generally move West to East through the stars, but occasionally stop and move in the opposite direction ( retrograde motion). In order to explain the retrograde motion of the planets, the geocentric model of the Solar System shown above puts the planets on small circles called epicycles . ...

Ultracompact dwarf galaxies (UCDs) are among the densest stellar systems in the Universe. With typical masses of 10^7 to 10^8 solar masses and half-mass radii between 10 to 100 pc they are more than a factor 1000 denser than dwarf galaxies of the same mass. They also show evidence for elevated mass-to-light ratios, which could be due to the presence of massive black holes or unusual stellar IMFs as a result of their extreme densities. ...

... We have examined the diversity of planets and planetary systems that arise from oligarchic growth and gas accretion onto massive cores, by means of N-body simulations combined with a sophisticated disc model. ... Slow planetary growth resulted from the relatively low mass of solids in the disc, and one consequence of this is that planets underwent limited orbital migration during the lifetime of the gas disc. ... Figure 1 shows an example of this migration behaviour in a single-planetin-a-disc run. ...

... The relationship of the mass and the observed galactocentric distance R -- (a), and that of the mass and the total dissipation velocity n taken from Gnedin, Ostriker (1997) -- (b). The dotted line in diagram (a) shows the "cone of survival" according to the paper by Surdin and Arkhipova (1998) . ... The solid line is a regression stright line for the main sequence of clusters, and the dotted line parallel to it separates the sequence of clusters of anomalously small mass shown by open triangles. ...

... Given the observing time and frequency, task plplt plots the expected visibility function for a planet. You will most likely want to check this visibility function before observing and discovering that the planet is resolved out! NOTE that mfboot and plplt do not include the effect of the ATCA's primary beam - the planet is implicitly (and silently) assumed to be small compared with the primary beam. ... Information on using the ATCA to observe a planet is available on-line . ...

... A dynamo is created in a magnetic field by an electric circuit, part of which is moving relative to the rest (additional conditions must also be met). ... Furthermore, the plasma between them conducts electricity very well along its magnetic field lines, which act as if they were wires connecting Io and the planet (drawing). ... The drawing is not to scale. ... The Hubble Space Telescope , using its Wide Field and Planetary Camera 2, has been photographing auroras of the planet Jupiter. ...

... Massive stars, having 10-150 masses of the Sun, with metallicities Z tens to hundreds times less than that of the Sun (Zo), are the main regulators of the galaxy formation and evolution processes in the early Universe. ... In this galaxy, using the 6 m BTA telescope, a new massive blue variable star with high luminosity (>=10 5 Sun's luminocities in visible light) was found. As far as its properties are concerned, this star falls into an LBV (Luminous Blue Variable) class of stars. ...
