The nature of supernovae


Baade & Zwicky 1934 [1]
tex2html_wrap_inline3922   Energy release ergs
tex2html_wrap_inline3922   Remnant could be a neutron star
tex2html_wrap_inline3922   Cosmic rays may form in supernovae
tex2html_wrap_inline3922   Expanding shells of gas km/s

Type I
tex2html_wrap_inline3922   Heavy element lines
tex2html_wrap_inline3922   From population II stars (low metalicity)
tex2html_wrap_inline3922   Occur in elliptical and spiral galaxies
tex2html_wrap_inline3922   1a - Merger or collapse of white dwarfs
tex2html_wrap_inline3922   1b - Carbon flash destroys star

Type II
tex2html_wrap_inline3922   Predominantly H lines
tex2html_wrap_inline3922   From population I stars (high metalicity)
tex2html_wrap_inline3922   Occur only in spiral galaxies
tex2html_wrap_inline3922   Core collapse in massive stars
