Cross-identifications of stars with high proper motions (Version 2.0)
Ivanov, G. A.
A cross index list of 493 200 stars with proper motions higher than 0.04″/yr (ftp://ftp.mao.kiev.ua/pub/astro/c-ihpms2) was compiled on the basis of the original determinations for the FONAK1.1 catalog stars, the data from the Hipparcos, Tycho-2, UCAC2, CMC (STAR 11), PPM, NPM1, NPM2, XZ80Q, Pul-3, PUL2, GCVS, NLTT, LHS, Lowell Proper Motion, and …
Constraints on the Velocity and Spatial Distribution of Helium-like Ions in the Wind of SMC X-1 from Observations with the XMM-Newton Reflection Grating Spectrometer
Kallman, Timothy R.; Liedahl, Duane A.; Wojdowski, Patrick S.
We present here X-ray spectra of the HMXB SMC X-1 obtained in an observation with the XMM-Newton observatory beginning before eclipse and ending near the end of eclipse. With RGS on board XMM-Newton, we observe emission lines from hydrogen-like and helium-like ions of nitrogen, oxygen, neon, magnesium, and silicon. Although the resolution of the R…
Determination of the IMF in the LMC Stellar Cluster NGC 2156
Silva-Villa, E.; Sirianni, M.; Zuluaga, J.
We present a study on the IMF of the stellar cluster NGC 2156 in the LMC from deep HST-WFPC2 images in the bands F555W and F814W. The study is part of a larger program to investigate whether the IMF at low stellar masses is dependent on local conditions by observing young globular clusters in the LMC and the SMC. We detected stars down to a limiti…
BVRI photometric analysis for the galaxy group NGC 4410
Meaburn, J.; Katsiyannis, A. C.; Khosroshahi, H. G. +4 more
We present a BVRI CCD (Charge Coupled Device) surface photometry analysis of the galaxy group NGC 4410, which contains four galaxies in interaction. Along with our photometric study, we show residual images (after subtracting isophotal models) and unsharp masked images to uncover any hidden structures in this system of galaxies; we have also perfo…
3D MHD reconnection model coupled with Cluster multi-spacecraft data
Nilsson, Hans; Balogh, André; Westerberg, Lars G. +2 more
We present a model where a three-dimensional viscous/resistive analytical model of the large scale plasma flow in the outflow region about a reconnection site at the dayside magnetopause, is coupled with multispacecraft measurements from the Cluster satellite armada. A total of ten magnetopause crossings have been analyzed during the period 10:29-…
X-ray spectroscopy of early-type stars: The present and the future
Nazé, Y.; Rauw, G.; Oskinova, L. M.
XMM-Newton and Chandra have boosted our knowledge about the X-ray emission of early-type stars (spectral types OB and Wolf-Rayet). However, there are still a number of open questions that need to be addressed in order to fully understand the X-ray spectra of these objects. Many of these issues require high-resolution spectroscopy or monitoring of …
Using X-ray observations to identify the particle acceleration mechanisms in VHE SNRs and ``dark'' VHE sources
Pühlhofer, G.
Very high energy (VHE) γ-ray observations have proven to be very successful in localizing Galactic acceleration sites of VHE particles. Observations of shell-type supernova remnants have confirmed that particles are accelerated to VHE energies in supernova blast waves; the interpretation of the γ-ray data in terms of hadronic or leptonic particle …
Catalogue of ionized emission line spectra in obscured AGN
Bianchi, S.; Guainazzi, M.; Salgado, J. +2 more
High-energy, high-resolution in the spatial and energy domains is crucial to derive the geometrical distribution and the physical properties of gas and dust surrounding Active Galactic Nuclei (AGN). These are, in turn, basic ingredients of any serious attempt to build an AGN structure model. We present in this paper CIELO-AGN, the first catalogue …
Flying SMART-1 to the Moon with Electric Propulsion
Milligan, D.; Gestal, D.; Camino, O.
The SMART-1 Lunar Mission was launched in September 2003, and operated from the European Space Operations Centre, in Darmstadt Germany. SMART-1's primary mission goal was to demonstrate Solar Electric Primary Propulsion by orbit raising from Geostationary Transfer Orbit to the Moon. Due to favourable thruster and power subsystem performance, and a…
Coronal mass ejection of April 27, 2003, and evolution of the active region NOAA 10338 in the radio
Kardapolova, N. N.; Borisevich, T. P.; Peterova, N. G. +1 more
The results of a study of the coronal mass ejection (CME) of April 27, 2003, which was intrinsically associated with the active region NOAA 10338, are reported. Particular attention is paid to the initial stage of the event, which was accompanied by X-ray bursts of class C9.3 and C6.7, with the aim of determining the origin of CMEs. The energy sou…
