This essay examines the place of love in grief, staging a relation between a mourner and her lover. Taking as its point of departure Freud's observation that mourning leads to a ‘loss of the capacity to love’, it considers the effects bereavement might have on the bereaved's relations with those that love them, and the possibilities, pitfalls and ethics of care in such a context. This is explored largely through a reading of Roland Barthes's late work, as well as ideas drawn from Sigmund Freud, Melanie Klein, Sara Ahmed, Hamlet and personal observation. Love and care are thought through alongside notions of ‘tact’, ‘benevolence’ and ‘parrying against reduction’ in late Barthes.

As a benchmark, we use a delayed-detonationmodel with a progenitormetallicity of Z⊙/20. We study the sensitivity of features to variations in progenitor metallicity, the outer density profile, and the distribution of radioactive nickel. The effect of metallicity variations in the progenitor have a relatively small effect on the synthetic spectra. We also find that the abundance stratification of SN 2011fe resembles closely that of a delayed-detonation model with a transition density that has been fit to other Branch-normal SNe Ia. At early times, the model photosphere is formed in material with velocities that are too high, indicating that the photosphere recedes too slowly or that SN 2011fe has a lower specific energy in the outer ≈0.1 M⊙ than does the model. We discuss several explanations for the discrepancies. Finally, we examine variations in both the spectral energy distribution and in the colours due to variations in the progenitor metallicity, which suggests that colours are only weak indicators for the progenitor metallicity, in the particular explosion model that we have studied. We do find that the flux in the U band is significantly higher at maximum light in the solar metallicity model than in the lower metallicity model and the lower metallicity model much better matches the observed spectrum.
