1. Stirling Colgate (1925--) when youthful with Geoffrey Burbidge, 1968. Stirling worked on the bombs during the 50s, pioneered SN Ia explosions and light curves during the 60s, was president of New Mexico Tech 1965--1975, was a pioneer robotic telescopes for supernovae in the 80s, and was still going when I last saw him circa 2003.
2. Les Houches Summer School, 1990, conference photo Eli Livne, coauthor of the paper of the day, and I used to meet up a meetings in the 90s. Here we are at the Les Houches Summer School in 1990. There's me behind Eli sitting on his haunches in the front. Despite appearances, it was a glorious summer day in the French Alps.
3. Nugent et al., 2011, Supernova 2011fe from an Exploding Carbon-Oxygen White Dwarf Star Everyone has believed it since the 60s, but this SN Ia confirmed pretty much that SN Ia progenitors were white dwarfs
4. Kushnir et al, 2013, The Progenitors of Type Ia Supernova Explosions are Head-On Collisions of White Dwarfs in Triple Systems The WD-WD head-on model or violent DD model explosions.
5. Katz & Dong, 2012, The rate of WD-WD head-on collisions may be as high as the SNe Ia rate Not a population synthesis paper.

   Caption: "Two bodies with similar mass orbiting around a common barycenter (red cross) with elliptical orbits." (Slightly edited.)

   The barycenter is the center of mass.

   The periapsis (AKA pericenter) is the arrangement of closest separation and the term is also used for the closest separation distance.

   The apoapsis (AKA apocenter) is the arrangement of farthest separation and the term is also used for the farthest separation distance.

   The relative semi-major axis is given by???

                        a=(1/2)( r_periapsis
                                +r_apoapsis )  .
