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/Polly-Pocket-Polly-Lila-Tropicool-Pineapple-Wearable-Purse-Compact/
