We present calculations of the light curves and spectra from
a suite of Type Ia supernovae models, ranging from
standard single degenerate scenarios to double degenerate
collisions. We use a fully relativistic and time dependent radiative
transfer code PHOENIX for our calculations which is time dependent
in both radiative transfer and rate equation. Simple hydrodynamic
calculation is used to treat conservation of energy of the gas and
the radiation together and also allow different time-scales for gas
and radiation. Between two time steps for the calculation of the
light curve, the correct distribution of total energy change among
gas and radiation is obtained by iteratively solving for the
radiative transfer equation and hence the new temperature in the new
time step. In our work we explore systematic relationships between the
mass of 56ni mass produced, the mass of silicon group elements
produced, the white dwarf metallicity, and the mass of unburned
material
