sdapy.models.arnett_tail.taum_to_MejEk

sdapy.models.arnett_tail.taum_to_MejEk(tau_m, taum_err=None, k_opt=None, sntype='Ic')

from characteristic time, taum (unit: day) to the product of kinetic energy (unit: foe) and ejecta mass (unit: solar mass), i.e. M$_{ej}^{3/4}$ E$_{kin}^{-1/4}$

Parameters

tau_mfloat

Arnett model parameter, characteristic time, unit in days, decided by ejecta mass and kinetic enegies.

taum_errfloat

Error of taum, if not setted, will return only value, otherwise will return value as well as error.

k_optfloat

diffusion opacity
