Abstract:
We report the discovery of the B[e] star VFTS 822 in the 30 Doradus
star-forming region of the Large Magellanic Cloud, classified by
optical spectroscopy from the VLT-FLAMES Tarantula Survey and
complementary infrared photometry. VFTS 822 is a relatively
low-luminosity (logL=4.04±0.25L☉) B8[e] star. In this Letter,
we evaluate the evolutionary status of VFTS 822 and discuss its
candidacy as a Herbig B[e] star. If the object is indeed in the
pre-main sequence phase, it would present an exciting opportunity to
spectroscopically measure mass accretion rates at low metallicity, to
probe the effect of metallicity on accretion rates.
