Query: A New Dust Budget In The Large Magellanic Cloud   The origin of dust in a galaxy is poorly understood. Recently, the surveys of
the Large Magellanic Cloud (LMC) provide astrophysical laboratories for the
dust studies. By a method of population synthesis, we investigate the
contributions of dust produced by asymptotic giant branch (AGB) stars, common
envelope (CE) ejecta and type II supernovae (SNe II) to the total dust budget
in the LMC. Based on our models, the dust production rates (DPRs) of AGB stars
in the LMC are between about $2.5\times10^{-5}$ and
$4.0\times10^{-6}M_\odot{\rm yr^{-1}}$. The uncertainty mainly results from
different models for the dust yields of AGB stars. The DPRs of CE ejecta are
about $6.3\times10^{-6}$(The initial binary fraction is 50\%). These results
are within the large scatter of several observational estimates. AGB stars
mainly produce carbon grains, which is consistent with the observations. Most
of dust grains manufactured by CE ejecta are silicate and iron grains. The
contributions of SNe II are very uncertain. Compared with SNe II without
reverse shock, the DPRs of AGB stars and CE ejecta are negligible. However, if
only 2 \% of dust grains produced by SNe II can survive after reverse shock,
the contributions of SNe II are very small. The total dust masses produced by
AGB stars in the LMC are between $2.8\times10^4$ and $3.2\times10^5M_\odot$,
and those produced by CE ejecta are about $6.3\times10^4$. They are much lower
than the values estimated by observations. Therefore, there should be other
dust sources in the LMC.
