Dust properties of the cometary globule Barnard 207 (LDN 1489)
  Barnard 207 (B207, LDN 1489, LBN 777), also known as the Vulture Head nebula,
is a cometary globule in the Taurus-Auriga-Perseus molecular cloud region. B207
is known to host a Class I protostar, IRAS 04016+2610, located at a projected
distance of ~8,400 au from the dense core centre. Using imaging and photometry
over a wide wavelength range, from UV to sub-mm, we study the physical
properties of B207 and the dust grains contained within. The core density,
temperature, and mass are typical of other globules found in the Milky Way
interstellar medium (ISM). The increase in the dust albedo with increasing
optical wavelengths, along with the detection of coreshine in the near
infrared, indicates the presence of larger dust grains in B207. The measured
optical, near-, mid- and far-infrared intensities are in agreement with the
CMM+AMM and CMM+AMMI dust grain type of The Heterogeneous dust Evolution Model
for Interstellar Solids (THEMIS), suggesting mantle formation on the dust
grains throughout the globule. We investigate the possibility of turbulence
being responsible for diffusing dust grains from the central core to external
outer layers of B207. However, in situ formation of large dust grains cannot be
excluded.
