LI-LMC 1813 is a dust-enshrouded Asymptotic Giant Branch ( AGB ) star , located in the small open cluster KMHK 1603 near the rim of the Large Magellanic Cloud ( LMC ) .
Optical and infrared photometry between 0.5 and 60 \mu m is obtained to constrain the spectral energy distribution of LI-LMC 1813 .
Near-infrared spectra unambiguously show it to be a carbon star .
Modelling with the radiation transfer code Dusty yields accurate values for the bolometric luminosity , L = 1.5 \times 10 ^ { 4 } L _ { \odot } , and mass-loss rate , \dot { M } = 3.7 ( \pm 1.2 ) \times 10 ^ { -5 } M _ { \odot } yr ^ { -1 } .
On the basis of colour-magnitude diagrams , the age of the cluster KMHK 1603 is estimated to be t = 0.9 –1.0 Gyr , which implies a Zero-Age Main Sequence mass for LI-LMC 1813 of M _ { ZAMS } = 2.2 \pm 0.1 M _ { \odot } .
This makes LI-LMC 1813 arguably the object with the most accurately and reliably determined ( circum ) stellar parameters amongst all carbon stars in the superwind phase .
