Detection of 6-cm radio-continuum emission from an EB (β-Lyrae type) variable star - HIP 68718
Filipović, M. D.; Anderson, M. W. B.
We report the 6-cm radio-continuum detection of a previously unknown radio star, HIP 68718, identified by the Hipparcos satellite as an EB or β-Lyrae type optical variable. Only five prior radio detections of this type are reported in the literature. The radio source (VLA J140402-002145) was detected at the 6σ level, with an associated <1arcsec…

Extraction of Halo Coronal Mass Ejection Asymmetry Information from LASCO Coronagraph Images
Webb, D. F.; Ling, A. G.
A method for quantifying the asymmetry attributes of coronal mass ejections (CMEs) is described. The technique developed is applied to a set of full-halo CMEs observed from 1997 to the end of 2000 by the Large Angle Spectrometric Coronagraph (LASCO) instrument on board the Solar and Heliospheric Observatory (SOHO) spacecraft. A cross section of ev…
Preface
Esposito, Larry W.; Stofan, Ellen R.; Cravens, Thomas E.
Venus has long been recognized as a sister planet to the Earth, as one of a triad of terrestrial planets with an atmosphere (Earth, Venus, Mars), and as a possible analogue for planets circling other stars. Its dense CO2 atmosphere has provided both a lesson and a warning in our understanding of the effects of greenhouse gases.
The…Searching for absorbed AGN in the 2XMM-Newton pre-release EPIC Serendipitous Source Catalogue
Watson, M. G.; Caccianiga, A.; Severgnini, P. +7 more
Aims:We aim to test a method of efficiently selecting X-ray obscured AGN in the 2XMM-Newton EPIC Serendipitous Source Catalogue.
Methods: By means of a strong correlation established using the XMM-Newton Hard Bright Sample between the intrinsic absorption and the hardness ratio to the 0.5-2.0 keV and 2.0-4.5 keV bands, an efficient way of sele…

The dynamics of the minimum solar corona during the period August October 1996
Schwenn, R.; Mierla, M.; Teriaca, L. +2 more
The paper presents the dynamics of the solar corona at the minimum phase of the solar cycle (period August-October 1996), as inferred from LASCO-C1 spectral data. LASCO-C1 is an internally occulted coronagraph aboard the SOHO spacecraft. It has a tunable Fabry-Pérot interferometer which allows taking spectral scans of selected coronal emission lin…
The COSAC experiment of the Rosetta mission: Performance under representative conditions and expected scientific return
Rosenbauer, H.; Szopa, C.; Goesmann, F. +2 more
The Cometary Sampling and Composition (COSAC) experiment is a combined gas chromatograph-mass spectrometer onboard the Philae cometary surface probe of the Rosetta mission. Its goal is to analyse, directly at the surface of a comet, the molecular and elemental compositions of the cometary nucleus samples collected by the probe. The present article…
Molecular content of a Type Ia supernova host galaxy at z = 0.6
Combes, F.; Melchior, A. -L.
We study the properties and the molecular content of the host of a Type Ia supernova (SN1997ey). This z = 0.575 host is the brightest submillimetre source of the sample of Type Ia supernova hosts observed at 450 and 850 µm by Farrah et al. Observations were performed at the Institut de Radioastronomie Millimétrique 30 m telescope (IRAM 30m) …
Variations of the ultraviolet resonance lines of the B2 IV-V star ζ Cassiopeiae
Smith, M. A.; Bohlender, D. A.
Recently Neiner et al. reported that the B2 IV-V star ζ Cas contains a weak magnetic field which varies on the same 5.37 day period found from the modulations of its N V, C IV, and Si IV UV resonance lines. We have studied the time variable properties of the same resonance lines in greater detail to determine the physical characteristics of the ma…
