3/30/2024 0 Comments Color coded periodic table 2018In its death throes, a low-mass star can have a much larger radius than a normal high-mass star. As this wonderful graphic from NASA’s Chandra website shows, all stars at the end of their lives swell up to red giant and supergiant stars. It does not make sense to think of nucleosynthesis origin having to do with the radius of the stars. I will assume that “Large Stars” and “Small Stars” are “High-Mass Stars” and “Low-Mass Stars”, respectively.The underlined phrases below represent possible topics for future blog posts where I (or colleagues I coerce bribe ask) can go into more in more detail later, including why we think we are on the right track. I am trying to avoid going into all details in this single blog post. In many cases, the Wikipedia graphic is presenting information that is flat-out wrong. Here is a discussion of the some of the differences between the Wikipedia version and mine. The former figure on Wikipedia was based on this plot from Northern Arizona Meteorite Laboratory Why does your version have different information than the well-known Wikipedia entry? However, the main point of this blog post is to present the chart and address the following question: There will be additional versions showing what this plot would look like if you were in the early Universe, or if you consider the origin of the elements on the Earth, etc. In an upcoming blog post, I will give details on my sources and assumptions for interested parties. This graphic draws on an enormous amount of labor from astronomers and physicists. I also updated the sources of the heavy elements to reflect the current semi-consensus. I have ignored the elements beyond U in this plot, but not including Tc and Pm looked weird, so I have included them in grey.įor this version, I tried to avoid the technical terms and jargon used in the original plot. Tc, Pm, and the elements beyond U do not have long-lived or stable isotopes. Elements with more than one source have the approximate amount due to each process indicated by the amount of area. My current version of the periodic table, color-coded by the source of the element in the solar system.
