A reanalysis of the extensive helioseismic data set from Big Bear Solar Observatory will be undertaken to extract all the information which it contains. A search will also be made for variation of the solar oscillations with the solar cycle since the data covers the entire interval from solar minimum to maximum. New precise radial velocity data will be obtained for bright solar type stars to attempt to detect individual p-mode oscillations analogous to those in the sun.

将对来自大熊太阳天文台的大量日震数据集进行重新分析，以提取其中包含的所有信息。由于数据涵盖了从太阳极小期到极大期的整个区间，因此还将研究太阳振荡随太阳周期的变化。明亮的太阳型恒星将获得新的精确径向速度数据，以尝试探测类似于太阳的单个p模振荡。
