Title:
High-resolution numerical studies for tidal detonation of a white dwarf

Abstract:
Theoretical considerations predict white dwarfs will experience 
thermonuclear explosions in the processes of tidal diruption events, 
so called ``tidal detonation''. Previous studies performed 
three-dimensional simulations to follow tidal detonation. 
However, their spatial resolutions are not high enough to investigate 
the start of tidal detonation. Tanikawa (2018, ApJ, 858, 26) have followed 
the start of tidal detonation accurately by one-dimensinal simulations 
with extremely-high spatial resolutions. In this talk, we will show results of 
a two-dimensional simulation for tidal detonation, 
and discuss the propatation and nucleosynthesis of the tidal detonation.
