matter and energy. Experiments have shown that all types of matter possess mass and occupy space. Hence, matter is defined as anything that occupies space, possesses mass and the presence of which can be felt by any one or more of our five senses....
, i.e.,\({[X]}=\log {X_{\mathrm{star}}} -\log {X_\odot }\)for any abundance quantity X, and\(\log {\epsilon (X)} = \log {N_{{X}}/N_{\mathrm{H}}} + 12.0\)for absolute number density abundances. For helium, we use Y, that is the fraction of He in mass....
