Global oscillations of the solar brightness.
Abstract
The Sacramento Peak Observatory vacuum tower telescope, echelle spectrograph, and diode array were used to search for global solar oscillations. The technique employed compares the relative intensity of a number of points on the solar disk and favors the detection of nonradial modes. In 6 days of observing, no narrow-band oscillations with periods between 15 and 90 minutes were found. The sensitivity per independent frequency interval is 0.0002 in contrast, or 0.3 K in temperature.
