vice.milkyway.mode¶
Type : str [case-insensitive]
Default : “ifr”
The interpretation of the attribute evolution.
mode = “ifr”: The value returned from the attribute
evolutionrepresents the surface density of gas infall into the interstellar medium in \(M_\odot kpc^{-2} yr^{-1}`\).mode = “sfr”: The value returned from the attribute
evolutionrepresents the surface density of star formation in \(M_\odot kpc^{-2} yr^{-1}\).mode = “gas”: The value returned from the attribute
evolutionrepresents the surface density of the interstellar medium in \(M_\odot kpc^{-2}\).
Note
The attribute evolution will always be expected to accept
radius in kpc and time in Gyr as the first and second parameters,
respectively. However, infall and star formation histories will be
interpreted as having units of \(M_\odot yr^{-1}\) according
to convention.
Note
Updating the value of this attribute also updates the
corresponding attribute of the J21_sf_law star formation law
where it has been assigned the attribute tau_star.
Example Code¶
>>> import vice
>>> mw = vice.milkyway(name = "example")
>>> mw.mode
"ifr"
>>> mw.mode = "sfr"
>>> mw.mode
"sfr"
