The NUADU experiment on TC-2 and the first Energetic Neutral Atom (ENA) images recorded by this instrument
Barabash, S.; Gunell, H.; Brinkfeldt, K. +13 more
The spacecraft potential of Double Star TC-1 is positive in large parts of the orbits due to the photo-effect from solar EUV irradiation. These positive potentials typically disturb low energy plasma measurements on board. The potential can be reduced, and thereby the particle measurements improved, by emitting a positive ion beam. This method has…
A far-infrared view of the Lockman hole from ISO 95-µm observations - II. Optical identifications and insights into the nature of the far-infrared sources
Rodighiero, G.; Franceschini, A.; Lari, C. +1 more
We present the optical identifications of a 95-µm ISOPHOT sample in the Lockman hole over an area of approximately half a deg2. The Rodighiero et al. catalogue includes 36 sources, making up a complete flux-limited sample for S95µm>= 100 mJy. Reliable sources were detected, with decreasing but well-controlled c…
GRBs Optical follow-up observation at Lulin observatory, Taiwan
Ip, W. H.; Tamagawa, T.; Makishima, K. +3 more
The Lulin GRB program, using the Lulin One-meter Telescope (LOT) in Taiwan started in July 2003. Its scientific aims are to discover optical counterparts of XRFs and short and long GRBs, then to quickly observe them in multiple bands. Thirteen follow-up observations were provided by LOT between July 2003 and Feb. 2005. One host galaxy was found at…
Discovery of multiple ultra-luminous X-ray sources in the galaxy KUG 0214-057
Akiyama, M.; Watson, M. G.; Roberts, T. P. +1 more
We report the serendipitous discovery of several unresolved X-ray sources lying in the prominent spiral arms of the galaxy
XMM-Newton observation of 4U 1543-475: The X-ray spectrum of a stellar-mass black-hole at low luminosity
Mereghetti, S.; La Palombara, N.
We report the results of an observation of the galactic black-hole binary 4U 1543-475 performed by XMM-Newton on 2002 August 18, about two months after the start of an outburst detected by RXTE. Despite the relatively low flux of the source, corresponding to a luminosity LX∼ 4× 1034 erg s-1∼ 10-5 LE…
The response of the near earth magnetotail to substorm activity
Khurana, K. K.; McPherron, R. L.; Thompson, S. +3 more
The large scale structure of the current sheet in the terrestrial magnetotail is often represented as the superposition of a constant northward-oriented magnetic field component ( Bz) and a component along the Earth-Sun direction ( Bx) that varies with distance from the center of the sheet ( z0 in GSM) as in a Hams…
First results of Chinese particle instruments in the Double Star Program
Dandouras, I.; Zhao, H.; Cao, J. B. +15 more
Double Star Program (DSP) aims to investigate the trigger mechanism and physical models of geomagnetic storms and substorms. The DSP involves two satellites: the equatorial satellite of DSP (TC-1 in China) and the polar satellite of DSP (TC-2 in China). On board the two satellites of TC-1 and TC-2, there are four kinds of particle instruments deve…
The Disk Atmospheres of Three Herbig Ae/Be Stars
Woodward, Charles E.; Temi, Pasquale; Wooden, Diane H. +1 more
We present infrared (IR) spectrophotometry (R~=180) of three Herbig Ae/Be stars surrounded by possible protoplanetary disks: HD 150193, HD 100546, and HD 179218. We construct a mid-IR spectral energy distributions (SEDs) for each object by using 7.6-13.2 µm HIFOGS spectra, 2.4-45 µm spectrophotometry from the Infrared Space Observatory…
Radial Velocities of Population II Binary Stars. Ii.
Bartkevičius, A.; Sperauskas, J.
Here we publish the second list of radial velocities for 91 Hipparcos stars, mostly high transverse velocity binaries without previous radial velocity measurements. The measurements of radial velocities are done with a CORAVEL-type radial velocity spectrometer with an accuracy better than 1 km/s. We also present the information on eight new radial…
A model grid for the spectral analysis of X-ray emission in young Type Ia supernova remnants
Badenes, Carles; Borkowski, Kazimierz J.; Bravo, Eduardo
We address a new set of models for the spectral analysis of the X-ray emission from young, ejecta-dominated Type Ia supernova remnants. These models are based on hydrodynamic simulations of the interaction between Type Ia supernova explosion models and the surrounding ambient medium, coupled to self-consistent ionization and electron heating calcu…
