Discovery of 7-13 HZ quasi-periodic oscillations in the new X-ray transient XTE J1806-246
Abstract
We have discovered quasi-periodic oscillations (QPO) with frequencies of 7-13 Hz (see the power density spectrum) in the recently discovered X-ray transient XTE J1806-246 (IAUC 6891) in data obtained on May 3 1998 21:03-22:31 UT with the proportional counter array (PCA) onboard the Rossi X-ray Timing Explorer. The total PCA count rate varied between approximately 7000 and 8000 counts/sec.
