... Earth-like planets are low mass compared to stars. Even so, planets revolve not around a host star’s center (axis of rotation); instead, both star and planets revolve around the planetary system’s barycenter (center of mass). Like a smaller boy gamely wrestling a bigger one, the gravitational mass o ...

Supernovae: Heavy Elements
... supernova have occurred in the history of our galaxy On average each explosion sends 10 solar masses of heavy elements back into space So, over 1 billion solar masses or 1% of all stellar mass is from supernova explosions Supernova explosions could easily be responsible for all of the iron and other ...

... (b) When the spectrum of a star is examined closely, specific absorption lines can be found. The positions (i.e. wavelength) and strengths of the absorption lines in the spectrum are “atomic fingerprints” of the elements and are unique for each element, thus the chemical composition of the atmospher ...
