Template:Starbox visbin

From Wikipedia, the free encyclopedia

Visual binary orbit

---

This is part of a group of templates that are used to display astronomical information related to a specific star. This template is used when the star has a visual companion and the orbital elements are available. It should always be preceded by a {{Starbox begin}} template. The template can then be used as follows:

{{Starbox visbin |
 reference=Reference |
 name=Companion name |
 period=Period, in years |
 axis=Semimajor axis, in arcseconds |
 axis_unitless=Semimajor axis, in arbitrary units |
 eccentricity=Eccentricity |
 inclination=Inclination, in degrees |
 node=Longitude of node, in degrees |
 periastron=Periastron epoch  |
 periarg=Argument of periastron, in degrees}}

The difference between the arguments axis and axis_unitless is that axis assumes the semimajor axis to be in arcseconds and appends the second symbol (") to it; axis_unitless does not do this, but the user may specify any desired unit inside the argument. Only one of axis and axis_unitless should be used.

Any of the arguments can be omitted if desired. If the argument generates a corresponding line, this line will then be omitted from the infobox. This template can also be preceded or followed by other Starbox templates:

• {{Starbox image}}
• {{Starbox observe}}
• {{Starbox character}}
• {{Starbox astrometry}}
• {{Starbox detail}}
• {{Starbox catalog}}
• {{Starbox reference}}

The list should then be closed with a {{Starbox end}} template.
