XMM-Newton observation of 4U 1543-475: The X-ray spectrum of a stellar-mass black-hole at low luminosity

DOI: 10.1051/0004-6361:200400123 Bibcode: 2005A&A...430L..53L

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 L_X∼ 4× 10³⁴ erg s^-1∼ 10^-5 L_E…

The response of the near earth magnetotail to substorm activity

DOI: 10.1016/j.asr.2004.03.024 Bibcode: 2005AdSpR..36.1818K

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 ( B_z) and a component along the Earth-Sun direction ( B_x) 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

DOI: 10.5194/angeo-23-2775-2005 Bibcode: 2005AnGeo..23.2775C

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

DOI: 10.1086/427968 Bibcode: 2005ApJ...622..430H

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.

DOI: 10.48550/arXiv.astro-ph/0601212 Bibcode: 2005BaltA..14..511B

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

DOI: 10.1016/j.asr.2005.01.019 Bibcode: 2005AdSpR..35..987B

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…

Optical Constraints on an X-ray Transient Source in M31

DOI: 10.1086/432597 Bibcode: 2005ApJ...631..832W

Williams, Benjamin F.; McClintock, Jeffrey E.; Murray, Stephen S. +2 more

We have detected a transient X-ray source in the M31 bulge through a continuing monitoring campaign with the Chandra ACIS-I camera. The source was detected at R.A.=00^h42^m33.428s+/-0.11", decl.=+41^deg17^'03.37"+/-0.11" in only a single observation taken 2004 May 23. Fortuitous optical HST ACS imaging of th…

Observations of the X-ray Burster MX 0836-42 by the INTEGRAL and RXTE Orbiting Observatories

DOI: 10.1134/1.2075311 Bibcode: 2005AstL...31..681C

Sunyaev, R. A.; Lutovinov, A. A.; Grebenev, S. A. +1 more

We present the results of our study of the emission from the transient burster MX 0836-42 using its observations by the INTEGRAL and RXTE X-ray and gamma-ray observatories in the period 2003 2004. The source’s broadband X-ray spectrum in the energy range 3 120 keV has been obtained and investigated for the first time. We have detected 39 X-ray bur…

Estimation of Projection Effect of CMEs from the Onset Time of the Shock-Associated Type III Radio Burst

Bibcode: 2005AcA....55..151M

Gopalswamy, N.; Michalek, G.; Yashiro, S.

We present a new possibility to estimate the projection effects on coronal mass ejection (CME) measurements. It is well known that coronagraphic observations of CMEs are subject to projection effects. Fortunately, the WIND/WAVES observations of type III radio bursts associated with shock waves are free from projection effects. We assume that (1) h…
