Catalogue of ROSAT White Dwarfs
Table1 lists all white dwarf stars, both previously-catalogued and newly discovered, which have been detected in the ROSAT All-Sky Survey. The positions and count rates of the... -
ROSAT observations of BL Lacertae objects
We present soft X-ray spectra of 74 BL Lacertae objects observed with the PSPC detector on board of the ROSAT satellite. The sample contains all BL Lac objects detected during... -
10 globular cluster ROSAT observations
We present X-ray observations of ten globular clusters observed with the ROSAT PSPC. The clusters were chosen to have large core radii and to be nearby. Three clusters contain... -
ROSAT study of Praesepe
We present the results of the ROSAT PSC observations of the Praesepe cluster. 68 Praesepe candidates have been detected, above a threshold of ~2x10^+28^erg/s (2x10^21^W), in the... -
T Tauri stars ROSAT survey
We study the X-ray emission of T Tauri stars (TTS) in Taurus-Auriga as observed with the spatially unbiased flux-limited ROSAT All-Sky Survey. Cone search capability for table... -
Second Catalogue of X-ray Sources
The catalog is a compilation of X-ray sources containing 677 objects known as of 1979 September. X-ray data for 677 sources are the result of X-ray sky surveys by rockets,... -
The WGACAT version of ROSAT sources
WGACAT is a catalogue of point sources generated at HEASARC from all the ROSAT PSPC (Position Sensitive Proportional Counter) pointing observations from Feb 1991 to March 1994.... -
ROSAT Source Catalog
This catalogue contains sources from PSPC-ROSAT (Position-sensitive Proportional Counter aboard the Roentgen Satellite), as provided by Max-Planck Institut fuer... -
XMM-Newton Observation Log
The XMM-Newton observatory is a cornerstone mission of the European Space Agency (ESA) Horizon 2000 program. This spacecraft, the largest ever flown by ESA for a scientific... -
The BAX Database
We present BAX, Base de Donnees Amas de Galaxies X (http://bax.ast.obs-mip.fr), a multi-wavelength database dedicated to X-ray clusters and groups of galaxies allowing detailed... -
VRI photometry in NGC 7129
NGC7129 is a bright reflection nebula located in the molecular cloud complex near l=105.4{deg}, b=+9.9{deg}, about 1.15kpc distant. Embedded within the reflection nebula is a... -
Spectroscopy of the quadruple system HD 91962
The young nearby solar-type star HD 91962 is a rare quadruple system where three companions revolve around the main component with periods of 170.3days, 8.85years, and 205years.... -
HD54662 radial velocities and X-ray light curves
HD 54662 is an O-type binary star belonging to the CMa OB1 association. Due to its long-period orbit, this system is an interesting target to test the adiabatic wind shock... -
Pre-main sequence stars in Scorpius OB1
The low-mass members of OB associations, expected to be a major component of their total population, are in most cases poorly studied because of the difficulty of selecting... -
XMM-Newton spectral survey of M31 disc
We present the results of a complete spectral survey of the X-ray point sources detected in five XMM-Newton observations along the major axis of M 31 but avoiding the central... -
ROSAT X-ray sources in LMC. II.
About 200 X-ray sources from a sample of spectrally hard ROSAT PSPC sources, given in the catalog of Haberl & Pietsch (1999, Cat. ), and observed in a ~60 square degree... -
SwiftFT catalog
An accurate census of the active galactic nuclei (AGN) is a key step in investigating the nature of the correlation between the growth and evolution of super massive black holes...
