We present Doppler and modulation tomography of the X-ray nova XTEJ1118+480 with data obtained during quiescence using the 10-m Keck II telescope. The hotspot where the gas stream hits the accretion disc is seen in Hα, Hβ, HeI λ5876 and CaII λ8662, thus verifying the presence of continued mass transfer within the system. The disc is clearly seen in

Dust Activity in Comet 67P/Churyumov Gerasimenko from February 20 to April 20, 2003
Broadband imaging of Comet 67P/Churyumov Gerasimenko has provided more data on the characterisation of the target of the ESA Rosetta Mission. The comet monitoring between r h=2.37 and r h=2.78 AU postperihelion shows a prominent dust coma which extends up to ≈ 25,000 km from the nucleus, and a long dust structure in approximately anti-tail

Dust properties in the circumstellar shells of evolved stars: Observational constraints from ISO and Spitzer infrared spectroscopy
We present the results of a systematic analysis of the solid state features identified in the circumstellar environments of a large sample of evolved stars with ISO/SWS and Spitzer/IRS spectroscopy. The sample includes several hundred stars with a wide variety of progenitor masses evolving from the early AGB phase to the PN stage. Our observations

Dust scattering and kinematics within the envelope of IRAS 09371+1212.
We have acquired narrow and broad band imaging, together with high and low resolution spectroscopy for the source IRAS 09371+1212. As a result, we are able to show the presence of systematic colour gradients within the interior and exterior envelopes. Whilst the interior bright lobes are characterised by relatively high values of V-R (a regime of

Dynamical evolution of globular cluster systems in clusters of galaxies - I. The case of NGC 1404 in the Fornax cluster
We investigate, via numerical simulations, the tidal stripping and accretion of globular clusters (GCs). In particular, we focus on creating models that simulate the situation for the GC systems of NGC 1404 and 1399 in the Fornax cluster, which have poor (specific frequency SN~ 2) and rich (SN~ 10) GC systems, respectively. We initially assign NGC

Dynamical evolution of two associated galactic bars
We study the dynamical interactions of mass systems in equilibrium under their own gravity that mutually exert and experience gravitational forces. The method we employ is to model the dynamical evolution of two isolated bars, hosted within the same galactic system, under their mutual gravitational interaction. In this study, we present an
