  During the early stages of an impact a small amount material may be jetted
and ejected at speeds exceeding the impact velocity. Jetting is an important
process for producing melt during relatively low velocity impacts. How impact
angle affects the jetting process has yet to be fully understood. Here, we
simulate jetting during oblique impacts using the iSALE shock physics code.
Assuming both the target and impactor have the same composition (dunite), we
examine the jetted material which exceeds the impact velocity. Our results show
that oblique impacts always produce more jetted ejecta than vertical impacts,
except for grazing impacts with impact angles $< 15^{\circ}$. A 45$^{\circ}$
impact with an impact velocity of 3 km/s produces jetted material equal to
$\sim$ 7 \% of the impactor mass. This is 6 times the jetted mass produced by a
vertical impact with similar impact conditions. We also find that the origin of
jetted ejecta depends on impact angle; for impact angles less than
45$^{\circ}$, most of the jet is composed of impactor material, while at higher
impact angles the jet is dominated by target material. Our findings are
consistent with previous experimental work. In all cases, jetted materials are
preferentially distributed downrange of the impactor.
