We investigate the numerical stability of thermonuclear detonations in 1D accelerated reactive shocks and 2D binary collisions of equal-mass magnetized and unmagnetized white dwarf stars. To achieve high resolution at initiation sites. we devised geometric gridding and mesh velocity strategies specially adapted to the unique requirements of head-on collisional geometries. scenarios in... https://www.roneverhart.com/Lethe-Eau-de-Toilette/
