Puzzling high-velocity calcium absorption features of type Ia supernovae.

ZHAO X.

Abstract (from CDS):

Absorption features Ca II NIR and Ca II H&K of type Ia supernovae (SNe Ia) are characterized by their strong high-velocity features (HVFs). We find that, for these two features of calcium there is a puzzling anticorrelation between the line strengths of HVF and photospheric (PHO) components, and an unexpected positive correlation between the velocity difference and line strength ratio of HVF and PHO components. In comparison, HVFs of Si II$\lambda$6355 and O I$\lambda$7773 show a positive correlation between the line strengths of HVF and PHO components, and no clear correlation between the velocity difference and line strength ratio of the two components. The differences may be associated with the fact that calcium was mostly synthesized in deeper layers than silicon and oxygen, and thus experienced much more serious blocking by substances in outer layers. These observations can shed light on the physics of HVFs.
