A class defining the Asplund (2009) solar abundance pattern.

The Asplund (2009) solar abundance pattern is a widely used reference abundance pattern for stars and galaxies. It is based on the solar abundances of elements and is often used as a standard for comparing the chemical composition of other stars and galaxies. The pattern includes the relative abundances of various elements, such as hydrogen, helium, carbon, nitrogen, oxygen, and others, in logarithmic form.

A class defining the Galactic Concordance abundance pattern.

The Galactic Concordance abundance pattern is a reference abundance pattern for stars and galaxies, based on the Galactic Concordance model. It is used to study the chemical evolution of galaxies and the formation of stars. The pattern includes the relative abundances of various elements, such as hydrogen, helium, carbon, nitrogen, oxygen, and others, in logarithmic form.

A class defining the Gutkin (2016) solar abundance pattern.

The Gutkin (2016) solar abundance pattern is a reference abundance pattern for stars and galaxies, based on the solar abundances of elements. It is used to study the chemical evolution of galaxies and the formation of stars. The pattern includes the relative abundances of various elements, such as hydrogen, helium, carbon, nitrogen, oxygen, and others, in logarithmic form.
