Abstract:
The Tarantula Nebula (a.k.a. 30 Dor) is a spectacular star-forming
region in the Large Magellanic Cloud (LMC), seen through gas in the
Galactic disc and halo. Diffuse interstellar bands (DIBs) offer a
unique probe of the diffuse, cool-warm gas in these regions.
The aim is to use DIBs as diagnostics of the local interstellar
conditions, whilst at the same time deriving properties of the
yet-unknown carriers of these enigmatic spectral features.
Spectra of over 800 early-type stars from the Very Large Telescope
Flames Tarantula Survey (VFTS) were analysed. Maps were created,
separately, for the Galactic and LMC absorption in the DIBs at 4428
and 6614AA and - in a smaller region near the central cluster
R 136 - neutral sodium (the NaI D doublet); we also measured
the DIBs at 5780 and 5797AA.
Description:
Equivalent widths of the 4428, 5780, 5797 and 6614 Diffuse
Interstellar Bands (DIBs) were measured for up to 800 OB-type stars in
the Tarantula Nebula (30 Doradus, containing the massive compact star
cluster R136) in the Large Magellanic Cloud (LMC). The Galactic
foreground and LMC components were fitted simultaneously, with
Lorentzians for the 4428 DIB and Gaussians for the other DIBs. All
fits were inspected by eye, and a flag was reset to zero if the fit
was rejected.
