The constants
module¶
A module which contains the following physical constants:
Name of variable | Quantity it describes | Units |
solar_radius |
the solar radius | \(\mathrm{cm}\) |
solar_mass |
the solar mass | \(\mathrm{g}\) |
solar_luminosity |
the solar luminosity | \(\mathrm{g.cm^2.s^{-3}}\) |
solar_temperature |
the solar effective temperature | \(\mathrm{K}\) |
solar_dnu |
the solar large frequency separation | \(\mathrm{\mu Hz}\) |
solar_numax |
the solar frequency at maximum power | \(\mathrm{\mu Hz}\) |
solar_cutoff |
the solar cutoff frequency | \(\mathrm{\mu Hz}\) |
G |
the gravitational constant | \(\mathrm{cm^3.g^{-1}.s^{-2}}\) |
solar_x |
the solar hydrogen content | dimensionless |
solar_z |
the solar metallicity content | dimensionless |
A_FeH |
multiplicative constant in \(\mathrm{[M/H]=A_{FeH}[Fe/H]}\) | dimensionless |
Note
These values can be edited according to the latest discoveries. As good practise, it is helpful to include the relevant reference.
