    Notes: [Auszug] Theories of the origin of the Solar System are necessarily uncertain, as the experiment that led to its formation cannot be repeated. But in the past few decades, our idea of how Earth and the other planets of the Solar System came to be has advanced from highly speculative musing to a true ...

    Notes: [Auszug] The meteorites and comets that were formed in the solar nebula, the planet-forming disk of gas and dust that became our Solar System, have been largely unaltered over time, and their structure provides clues about the physical and chemical processes that occurred in the nebula. One group of early ...

    Notes: [Auszug] Planet hunters keep discovering yet more weird objects around nearby Sun-like stars that resemble nothing found in our own Solar System. The latest discoveries, announced at a meeting earlier this month*, include a three-body system that appears to be composed of a central star orbited by ...

    Notes: [Auszug] Looking at the night sky with the naked eye gives the impression that nearly all stars are single stars, much like our Sun. In reality, roughly half of these stars are binaries — two stars revolving around a common centre of mass. Studies of star formation have focused largely on single ...

    Notes: [Auszug] Size does matter, especially when it comes to radio telescopes. With a maximum extent of 36 km, the Very Large Array (VLA) of 27 radio telescopes yields sharper images at millimetre wavelengths than any other instrument. Rodríguez et al., reporting on page 355 of this issue, have ...

    Notes: [Auszug] The discovery of giant planets orbiting nearby solar-type stars raises anew the question of how they formed. Two very different mechanisms have been proposed. Gravitational instability, is the process by which planets form directly from the gas in the accrection disk around the young star. The ...

    TEMPERATURES IN PROTOPLANETARY DISKS (1998)
    Palo Alto, Calif. : Annual Reviews
    Annual Review of Earth and Planetary Sciences 26 (1998), S. 53-80 
    Details
    ISSN: 0084-6597
    Source: Annual Reviews Electronic Back Volume Collection 1932-2001ff
    Topics: Geosciences , Physics
    Notes: Abstract Observations of suspected planet-forming disks provide estimates of protoplanetary disk masses, surface temperatures, and the rate at which mass is infalling onto the disks. Analyses of primitive meteorites and comets and their components constrain the solar nebula's temperature at the locations and times where those components were formed. Theoretical models of disks undergoing the accretion of mass from an infalling cloud envelope predict disk temperatures in good agreement with these constraints: a moderately warm (500-1500 K) inner disk, surrounded by a cool (50-150 K) outer disk. These models have important implications for the depletion of volatiles in the inner Solar System, for mechanisms of disk evolution, and for the orbital distances at which terrestrial and gas giant planets form.

    Notes: [Auszug] Fragmentation during the isothermal collapse phase of pro-tostellar evolution is one of the leading mechanisms for explain-ing the formation of binary and multiple stars9"13. Although it is well known that fragmentation can form binary protostellar cores or trapezium-like (unstable) multiple ...

From models of the possible equilibrium states available to interstellar clouds and their protostellar progeny, ...
