We conducted a search for narrowband artificial signals from the regions of stars around which planetary companions have been recently found: 51 Pegasi, Gliese 229, 70 Virginis, and 47 Ursae Majoris. We used the large Nangay decimetric telescope, with a frequency resolution of 50 Hz, and we scanned over 0.64 and 2.24 MHz respectively around the hydrogen and hydroxyl lines.
