XMM spectroscopy of the transient supersoft source RXJ0513.9 - 6951: probing the dynamic white dwarf photosphere
No full textThe highly luminous (>1037 erg s?1) supersoft X-ray sources (SSSs) are believed to be Eddington-limited accreting white dwarfs undergoing surface hydrogen burning. The current paradigm for SSSs involves thermally unstable mass transfer from a 1–2M companion. However, this model has never been directly confirmed and yet is crucial for the evolution of cataclysmic variables (CVs) in general, and for the establishment of SSSs as progenitors of Type Ia supernovae in particular. The key SSS is RX J0513.9?6951 which has recurrent X-ray outbursts every 100–200 d (lasting for ?40 d) during which the optical brightness declines by 1 mag.We present the firstXMM observations of RX J0513.9?6951 through one of its optical low states. Our results show that as the optical low state progresses, the temperature and X-ray luminosity decrease, behaviour that is anti-correlated with the optical and ultraviolet (UV) emission. We find that as the optical (and UV) intensity recovers, the radius implied by the
spectral fits increases. The high-resolution spectra show evidence of deep-absorption features which vary during the optical low state. Our results are consistent with the predictions of the white dwarf photospheric contraction model proposed by Southwell et al

Moving towards 3D: From a national mapping agency perspective
No full textOrdnance Survey is the national mapping agency of Great Britain We are always developing our product line and are currently investigating the addition of 3D data. In line with our role as a national mapping agency the approach is to do this, such that any data is part of a coherent range of products that are sympathetic with the terrain and existing 2D topographic data, are of national cover and are maintained. Such intentions create unique challenges to a mapping agency. These challenges include: 1. Specification determination and an appropriate capture methodology. 2. Data modelling and storage of 3D data. 3. Maintenance of the database. 4. Supply of products in a useful format. This paper will discuss those issues most pertinent to the development of a potential 3D product within Ordnance Survey. Subsequently, a better understanding of the complexity of implementing a 3D dataset into a national mapping agency's product portfolio can be achieved
