The 1979 differential radius observations of the Sun have been reexamined for additional evidence of gravity modes (g-modes) beyond that reported by Hill and to classify the modes for which evidence has been obtained....The 1979 differential radius observations of the Sun have been reexamined for additional evidence of gravity modes (g-modes) beyond that reported by Hill and to classify the modes for which evidence has been obtained. The basic criteria employed in the mode detection and classification procedure are extensions of the criteria introduced by Hill. The properties of the 31 multiplets classified by Hill are used as the starting point in the work reported here. Statistically significant evidence of additional g-modes has been found and the number of classified multiplets is extended from 31 to 53. The degrees and radial orders of the 53 multiplets are respectively l=1, n=47,…, 7; l=2, n=6,…, 13, 15 and 16; l=3, n=7,…, 20; l=4, n=7,…, 20; and l=5, n=16,…, 26. The m=0 eigenfrequencies are measured with an accuracy of ≈0.02 μHz and the multiplet structure linear in angular order m is measured with an accuracy of ≈0.01 μHz.展开更多
