名前	型	説明
`name`	`string`	The star's name (`Sirius B`, `Proxima Centauri`).
`nameJa`	`string \| undefined`	The name in Japanese where it has one, else `undefined`.
`role`	`"primary" \| "companion"`	`"primary"` for the star the system's values are the values of (the brightest, or the one the table names), else `"companion"`.
`rightAscension`	`number \| undefined`	Right ascension in degrees at J2000, or `undefined` for a companion the Yale tables do not hold (it is close beside the primary).
`declination`	`number \| undefined`	Declination in degrees at J2000, or `undefined` as above.
`lightYears`	`number \| undefined`	The star's own distance in light-years, or `undefined` as above.
`spectralType`	`string \| undefined`	The spectral type, or `undefined` where the source gives none.
`luminosityClass`	`LuminosityClass \| undefined`	The luminosity class in `spectralType`, or `undefined` where it states none (a white dwarf is `D` only where the type starts with `D`).
`magnitude`	`number \| undefined`	The V magnitude, or `undefined` where there is none.
`source`	`NearStarSource`	Where the star's values come from: `"typed"` for a published value typed into the package.
`note`	`string \| undefined`	A word about the star (`a white dwarf`, `a brown dwarf`), or `undefined`.
