摘要：

A 5-hr observation of PG0834+488 using the EXOSAT X-ray observatory has resulted in its detection as an X-ray source. The light curve shows marginal evidence for variability but no coherent periodicities were found. The X-ray spectrum was hard, with a photon index of ∼1.36, and the low-energy absorption implied a low column density NH∼4.2×1020 cm-2. At an assumed distance of 100 pc the 2-6 keV X-ray luminosity would be ∼1.4×1031 erg s-1 © 1985 Royal Astronomical Society. Provided by the NASA Astrophysics Data System.
