Effects of Gravitational Microlensing on P Cygni Profiles of Type Ia Supernovae

A brief description of the deformed spectra of microlensed SNe Ia is presented. We show that microlensing amplification can have significant effects on line profiles. The resonance-scattering code SYNOW is used to compute the intensity profile in the rest frame of the supernova. The observed (lensed) spectra are predicted assuming a simple stellar-size deflector, and are compared to unlensed cases to show what effects microlensing can have on spectral lines. We limit our work to spherically symmetric deflectors.
