Many different classes of X-ray sources contribute to the Galactic landscape at high energies. Although the nature of the most luminous X-ray emitters is now fairly well understood, the population of low-to-medium X-ray luminosity (LX = 1027-34 erg s

High-resolution observations of cool stars with the ESO Coude' Echelle Spectrometer
Autor: M. Pakull, R. Pallavicini
Publikováno v: Cool Stars, Stellar Systems, and the Sun ISBN: 9783540129073
A new instrument capable of providing high spectral resolution observations of relatively bright objects became operational in 1982 at the European Southern Observatory (ESO) at La Silla (Chile). This is the Coud~ Echelle Spectrometer (CES), which in

A New PG 1159-Type Central Star Discovered in the ROSAT XRT All Sky Survey: Non-LTE Analysis of X-Ray and Optical Spectra
Autor: K. Werner, C. Motch, M. Pakull
Publikováno v: Symposium - International Astronomical Union. 155:496-496
We report on the discovery of a new PG 1159 star in the ROSAT XRT all sky survey and give results of a model atmosphere analysis. The X-ray source RX J2117.1+3412 is relatively faint (0.33 cnts−1) and extremely soft. Ground based optical follow-up

Autor: S. A. Ilovaisky, Christian Motch, M. Pakull, C. Chevalier
Publikováno v: X-Ray Astronomy in the Exosat Era ISBN: 9789401089067
We present preliminary results from V-band CCD photometric observations of several low-mass X-ray binaries with faint optical counterparts obtained at ESO and CFHT from February to September 1984. LMCX-2 exhibits large (0.3–0.5 magnitude) variation
