This template is for use on List of largest known stars to calculate the radius of a star and format the table row if the explicit radius is not given in the source. If the source provides both the radius and method of detection, this template is not required and the information can be entered in as usual with table notation.
Usage
editIf a single value is to be calculated, use one of the following parameters, as well as |ref=
:
Parameter(s) | Description | |
---|---|---|
|Rcm= |
|AD=yes or |LT=yes [a]
|
Radius in cm |
|Rm= |
Radius in m | |
|logL= |
|temp= |
Logarithm of luminosity (L☉), temperature (K) |
|L= |
|temp= |
Luminosity (L☉), temperature (K) |
|mas= |
|kpc= |
Angular diameter (milliarcseconds), distance (kpc) |
- ^ Needed to display "method" information.
If multiple values are to be displayed, then append the appropriate "1" or "2" to the value, e.g. |Rcm1=
, |L2=
, and |temp2=
. Unless the two values come from the same source, |ref1=
and |ref2=
will be required.
If notes are needed, use |notes=
.
Examples
editBelow are examples of how this template can be used, followed by the raw code for each row.
Star name | Solar radii (Sun = 1) |
Method | Notes |
---|---|---|---|
Example star | 3,000[1] | AD | This row has been entered directly without using the template |
IRAS 05280-6910 | 1,739[2] | L/Teff | Uses Rcm and LT |
Stephenson 2-18 | 2,150[3] | L/Teff | Uses logL and temp |
VY Canis Majoris | 1,458[4] | AD | Uses mas and kpc |
Example star | 1,458[4]–2,021[3] | AD & L/Teff | Uses mas1, kpc1, logL2, temp2, ref1 and ref2 |
