Using XMM-Newton and Optical Photometry to Figure Out CVs

Bibcode: 2006JAVSO..35..306S

Szkody, P.; Henden, A.; Homer, L.

X-ray light curves from XMM-Newton combined with optical data from the satellite and ground-based observers provide distinctive shapes and periodicities that give information on the correct classification of cataclysmic variables. Our recent data on three SDSS sources with strong helium emission are used to identify a highly magnetic system (a pol…

Automated spectral and timing analysis of AGNs

DOI: 10.1002/asna.200610699 Bibcode: 2006AN....327.1094M

Guainazzi, M.; Karas, V.; Munz, F.

% We have developed an autonomous script that helps the user to automate the XMM-Newton data analysis for the purposes of extensive statistical investigations. We test this approach by examining X-ray spectra of bright AGNs pre-selected from the public database. The event lists extracted in this process were studied further by constructing their e…

High-Energy Astrophysics and the Virtual Observatory

DOI: 10.1088/1009-9271/6/S1/07 Bibcode: 2006ChJAS...6a..73P

Padovani, Paolo

The Virtual Observatory (VO) will revolutionise the way we do Astronomy by allowing easy access to all astronomical data and by making the handling and analysis of datasets at various locations across the globe much simpler and faster. I report here on the need for the VO and its status in Europe, concentrating on the recently started EURO-VO proj…

²⁶Al spectroscopy with SPI: The challenge to detect Galactic rotation

DOI: 10.1016/j.asr.2006.09.027 Bibcode: 2006AdSpR..38.1439K

Strong, A. W.; Hartmann, D. H.; Diehl, R. +1 more

The shape of the γ-ray line from radioactive ²⁶Al, at 1808.7 keV energy in the frame of the decaying isotope, is determined by its kinematics when it decays, typically 10 ⁶ yr after its ejection into the interstellar medium from its nucleosynthesis source. Three prior measurements of the line width exist: HEAO-C's 1982 value …

Adaptive-randomised self-calibration of electro-mechanical shutters for space imaging

DOI: 10.1016/j.ymssp.2006.03.014 Bibcode: 2006MSSP...20.2305D

Debei, Stefano; De Cecco, Mariolino; Zaccariotto, Mirco +1 more

This work describes the self-calibration of a high-precision open-loop mechanism. The self-calibration method is applied to a mechanical shutter for space applications, which was launched onboard the ESA-ROSETTA mission (launch: 2 March 2004). It is based on an adaptive 'model reference' and a 'randomised' search method which may be generalised to…

The Spatial Distribution of W UMa-Type Stars

DOI: 10.1007/s10509-006-9089-9 Bibcode: 2006Ap&SS.304..121O

Ogloza, Waldemar; Zakrzewski, Bartlomiej

The aim of this project is to study the spatial distribution of contact binaries and to compare the sample from the project of study the W UMa-type stars, with existing databases such as Hipparcos, GCVS or ASAS (ESA, 1997; GCVS, 2005; Pojmanski, 2002).

Cluster, a joint project between the European Space Agency (ESA) and NASA, is the first mission that is composed of four spacecraft flying in formation, and thus the first able to separate spatial and temporal features inside smallscale plasma structures within, and the boundaries between, many regions of the Earth's upper atmosphere (from 19,000-…

Graphical method for estimation of accuracy of astrometric catalogues

Bibcode: 2006KFNT...22..219N

Nefedjev, Yu. A.; Rizvanov, N. G.; Rakhimov, L. I. +1 more

We propose a new method for the estimation of the accuracy of star positions and proper motions in astrometric catalogues based on the comparison of the star positions in catalogue a under investigation and the HIPPARCOS catalogue in various epochs but for a standard equinox. In this case the comparison results are represented as a curve. On the a…

On the concepts of a highly integrated payload suite for use in future planetary missions: The example of the BepiColombo Mercury planetary orbiter

DOI: 10.1016/j.actaastro.2005.07.016 Bibcode: 2006AcAau..59..823K

Schulz, R.; Erd, C.; Buis, E. J. +6 more

Future low resource payload concepts will need to be developed from the viewpoint of a standard integrated payload suite where resources are dramatically reduced through high levels of integration and resource sharing. The study of this approach, its gains together with its limitations was the key objective of this work. The highly compact integra…
