IAU recommendations for nominal units

The IAU 2015 resolution B3 defines nominal solar and planetary values by establishing conversions between solar and planetary values and SI units. The rational and specifications are given in \citet{2016AJ....152...41P}. The recommended nominal conversion constants for \latex have been incorporate into v6.31 to help authors follow the IAU resolution.

The general commands take this form:

\vskip12pt \begin{center} \begin{tabular}{@{\vrule height 14pt depth 6pt width0pt}lll} Command&Example&Results\ \verb+\nom{}+&\verb+\nom{Q}+&\nom{Q}\ \verb+\Eenom{}+&\verb+\Eenom{Q}+&\Eenom{Q}\ \verb+\Epnom{}+&\verb+\Epnom{Q}+&\Epnom{Q}\ \verb+\Jenom{}+&\verb+\Jenom{Q}+&\Jenom{Q}\ \verb+\Jpnom{}+&\verb+\Jpnom{Q}+&\Jpnom{Q}\ \end{tabular} \end{center} \vskip12pt

which can be used for any units the author requires. Examples of the most common uses would be:

\vskip12pt \begin{tabular}{@{\vrule height 14pt depth 6pt width 0pt}llllp{3in}} 1.&\verb+\nom{(GM)}+& \nom{(GM)} &=& nominal solar mass parameter\ 2.&\verb+\nom{R}+&\nom{R} &=& nominal solar radius\ 3.&\verb+\nom{S}+& \nom{S}&=& nominal total solar irradiance\ 4.&\verb+\nom{L}+& \nom{L} &=&nominal solar luminosity\ \end{tabular} \vskip12pt

AASTeX v6.31 also contains specific commands for other commonly used units. These are:

\vskip24pt \begin{tabular}{@{\vrule height 14pt depth 6pt width 0pt}llllp{3in}} 1.&\verb+\nomSolarEffTemp+& \nomSolarEffTemp&=& nominal solar effective temperature\ 2.&\verb+\nomTerrEqRadius+&\nomTerrEqRadius &=& nominal terrestrial equatorial radius\ &\verb+\nomTerrPolarRadius+ &\nomTerrPolarRadius &=& nominal terrestrial polar radius\ &\verb+\nomTerrEqRadius+&\nomTerrEqRadius&& should be used if equatorial vs.~polar radius is not explicitly specified.\ 3.&\verb+\nomJovianEqRadius+&\nomJovianEqRadius&=& nominal one-bar equatorial radii of Jupiter\ &\verb+\nomJovianPolarRadius+&\nomJovianPolarRadius &=& nominal polar radii of Jupiter\ &\verb+\nomJovianEqRadius+&\nomJovianEqRadius&& should be used if Jovian equatorial vs.~polar radius is not explicitly specified.\ 4.&\verb+\nomTerrMass+ &\nomTerrMass &=& nominal terrestrial mass parameter\ &\verb+\nomJovianMass+ &\nomJovianMass &=& nominal Jovian mass parameter\ \end{tabular} \vskip12pt

All of these commands work equally well in text and math mode.

Using Chinese, Japanese, and Korean characters

Authors have the option to include names in Chinese, Japanese, or Korean (CJK) characters in addition to the English name. The names will be displayed in parentheses after the English name. The way to do this in AASTeX is to use the CJK package available at \url{https://ctan.org/pkg/cjk?lang=en}. Further details on how to implement this and solutions for common problems, please go to \url{https://journals.aas.org/nonroman/}.
