... hotter than the surface of the Sun – approximately 300,000 degrees Kelvin. To populate a galaxies CGM with heavy elements it takes massive amounts of energy from supermassive black holes and exploding supernovae in violent and long-lasting...
... several generations of the star birth and star death cycle to populate a galaxy with heavy elements, and once liberally strewn about, the elements can then become the material with which planets are built. “Young, primordial...
... radius — substantially more than previous estimates. It is also composed of a diffuse mixture of hydrogen and helium combined with heavy elements, and contains approximately 17 Earth masses of ice and rock, say Mankovich and Fuller. This is contrary...
.... During this process, a newly coagulated planet warms up and different chemical elements start to separate - heavy elements sink to the bottom, while lighter elements are pushed to the outer layers. A number of chemical changes also take...
... unexplained observations such as titanium enriched supernovae and the processing of elements heavier than iron, as it is suggested that supernova alone cannot produce the heavy element abundance seen in the Sun for example. Those researching the...
...peculiar chemical gas from a companion star that made these chemical elements in the past. Today that companion is likely too faint to...-stars merge, not only does the process produce the heavy elements found in our Galaxy, such as gold, platinum and...
