Wakusei Planets惑星

The Sun, the planets and their moons as a clean line drawing, a shaded realistic drawing or a painted surface map, with real sizes, tilt and rotation, and the moons where they are at any date and time.

Wakusei is the Japanese word 惑星 for a planet. About the name

RadiusRowtype

One row of the radius table: a star, its radius in Suns with the error on each side, how it was got, and the paper. how says whether the radius is the paper's own (paper) or was worked out here from numbers the paper gives (worked-out: the radius of an angular diameter at the paper's distance, or of a luminosity and a temperature by the Stefan-Boltzmann law).

Import it

NameTypeDescription
idstring

A short key: sirius-a.

name{ en: string; ja: string; }
radiusSunnumber

The radius in solar radii (equatorial, for a star that is flattened).

minusnumber

The error below and above the radius, in solar radii, both positive or 0.

plusnumber
basisRadiusBasis
how"paper" | "worked-out"
method{ en: string; ja: string; }

One sentence: what was measured and how the radius follows.

thetaMas (optional)number | undefined

The measured angular diameter in milliarcseconds (limb-darkened, or Rosseland where the paper says so), when the radius comes from one.

distancePc (optional)number | undefined

The distance in parsecs when it is the paper's own result and not a catalogue parallax (the catalogue parallaxes of Hipparcos and Gaia are not copied here).

citestring

The papers, as a short citation for a label.

bibcodesreadonly string[]

The ADS bibcodes of the papers the radius and the temperature come from, the first being the radius's.

readstring

The date the paper was read, YYYY-MM-DD.

note (optional){ en: string; ja: string; } | undefined

What the literature disagrees about, when it does: it goes on the label and in the guide.

others (optional)readonly { radiusSun: number; cite: string; why: { en: string; ja: string; }; }[] | undefined

Other published radii that are not used, and why.

lookOmit<StarNumbers, "radiusSun" | "estimated" | "name">

What the star is drawn from: the temperature, its class and the rest. The radius is filled in from this row.

temperatureFromstring

Where the temperature comes from.

Examples

import { LINEUP_STARS, type RadiusRow } from "@johnmorrisdotca/wakusei-planets";

const row: RadiusRow = LINEUP_STARS.find((one) => one.id === "betelgeuse")!;
console.log(row.radiusSun, row.bibcodes[0]);
