The occultation events of the Herbig Ae/Be star V1247 Orionis.


Abstract (from CDS):

I study new deep (ΔV≃1.20-1.65mag) occultation events of the δ Scuti, Herbig Ae/Be star V1247 Ori in the Ori OB1b association. I use the V-band ASAS light curve of V1247 Ori, which covers the last nine years, together with photometric data in the near-ultraviolet, visible, near-, and far-infrared taken from the literature. I carry out a periodogram analysis of the ``cleaned'' light curve and construct the spectral energy distribution of the star. The star V1247 Ori is interesting for the study of the UX Orionis phenomenon, in which Herbig Ae/Be stars are occulted by their protoplanetary discs, for three reasons: brightness (V≃9.85mag), large infrared excess at 20-100µm (F60≃10Jy), and photometric stability out of occultation (σ(V)≃0.02mag), which may help to determine the location and spatial structure of the occulting disc clumps.
