The early X - ray emission from V 382 Velorum ( = Nova Vel 1999 ) : An internal shock model
We present the results of ASCA and RXTE observations of the early X-ray emission from the classical nova V382 Velorum. Its ASCA spectrum was hard (kT∼10 keV) with a strong (10 cm) intrinsic absorption. In the subsequent RXTE data, the spectra became softer both due to a declining temperature and a diminishing column. We argue that this places the X-ray emission interior to the outermost ejecta ...
متن کاملTesting the line-driven disk wind model: time-resolved UV spectroscopy of IX Vel and V3885 Sgr
To confront the predictions of the most recent line-driven disk wind models with observational evidence, we have obtained HST STIS (1180–1700Å) echelle spectra of the nova-like variables IX Vel and V3885 Sgr at three epochs. The targets were observed in timetag mode for ∼2000 sec on each occasion, allowing us to study the spectral time evolution on timescales down to ∼10 sec. The mean UV spectr...
متن کاملTerra Cognita and Semantic Sensor Networks
The French national mapping agency (IGN) produces several different but complementary geographic vector reference databases delivered in traditional GIS formats. However, linked data users have different expectations and habits, such as the need to browse an entire data catalogue in RDF using the ”follow-your-nose” navigation capacity from one graph to another. Besides, traditional GIS data for...
متن کاملDesigner orthopaedic surgery in a patient with anti-Vel antibodies.
The authors present a rare case of anti-Vel antibodies in a patient who underwent a shoulder replacement with a custom designed procedure which involved combination of autologous blood pre-deposit, pre-operative haemodilution and resurfacing arthroplasty.
متن کاملTerra Cognita: Using Earth Observing Systems to Understand Our World
Background: The need for discovery of alternative, renewable, environmentally friendly energy sources and the development of cost-efficient, "clean" methods for their conversion into higher fuels becomes imperative. Ethanol, whose significance as fuel has dramatically increased in the last decade, can be produced from hexoses and pentoses through microbial fermentation. Importantly, plant bioma...
