Environments of Type Ia Supernovae with Different Relative Equivalent Widths of the Si ii Feature in Their Spectra
Although type Ia supernovae (SNe Ia) are very important in many astrophysical fields, such as cosmology, their explosion mechanisms and progenitor systems still remain unclear. In physics, the relative equivalent width (REW) of the Si ii 635.5 nm absorption feature reflects the velocity interval of...
