Abstract: Abstract We propose that certain white dwarf (WD) planets, such as WD 1856+534 b, may form out of material from a stellar companion that tidally disrupts from common envelope evolution with the WD progenitor star.… read more here.

Abstract: We outline the methodology of simulating common envelope evolution (CEE) with the moving-mesh code manga. We extend manga to include multiple time-steps. This provides substantial speedups for problems with large dynamic range. We describe the… read more here.

Abstract: We analyze a 3D hydrodynamic simulation of common envelope evolution to understand how energy is transferred between various forms and whether theory and simulation are mutually consistent given the setup. Virtually all of the envelope… read more here.
