How do f-mode Frequencies Change with Solar Radius?
نویسنده
چکیده
We test the relation between relative f -mode frequency variation (δν/ν) and Lagrangian perturbation in the solar radius (δr/r) obtained by Dziembowski & Goode (2004) using several pairs of solar models and show that it doesn’t hold true for any of the model pairs we have used. We attempt to derive a better approximation for the kernel linking the relative frequency changes and the solar radius variation in the subsurface layers. Subject headings: Sun: oscillations – Sun: helioseismology

We have analysed temporal evolution in centroid frequencies and splitting coefficients of solar f-modes obtained from MDI/SOHO. The data were divided into 20 sets covering a period from May 1, 1996 to August 31, 2000. The variation in frequencies is estimated to be 68 nHz over the period of four years which includes the rapidly rising phase of the solar cycle 23. This change is much smaller tha...
متن کاملSolar gravitational energy and luminosity variations
Due to non-homogeneous mass distribution and non-uniform velocity rate inside the Sun, the solar outer shape is distorted in latitude. In this paper, we analyze the consequences of a temporal change in this figure on the luminosity. To do so, we use the Total Solar Irradiance (TSI) as an indicator of luminosity. Considering that most of the authors have explained the largest part of the TSI mod...
متن کاملDetermination of the Sun's Seismic Radius from SOHO/MDI
Dopplergrams from the Michelson Doppler Imager (MDI) instrument on board the SOHO spacecraft have been used to accurately measure frequencies of the Sun's fundamental (f) mode in the medium angular degree range, l = 88 ? 250. The comparison of these frequencies with the corresponding frequencies of the standard solar models suggests that the apparent photospheric solar radius (695.99 Mm) used t...
متن کاملDoes the Sun Shrink with Increasing Magnetic Activity?
We have analyzed the full set of Solar and Heliospheric Observatory (SOHO) Michelson Doppler Imager (MDI) fand p-mode oscillation frequencies from 1996 to date in a search for evidence of solar radius evolution during the rising phase of the current activity cycle. Just as Antia et al. in 2000, we Ðnd that a signiÐcant fraction of the f-mode frequency changes scale with frequency and that if th...
متن کاملEMPIRICAL ESTIMATE OF p-MODE FREQUENCY SHIFT FOR SOLAR CYCLE 23
We have obtained empirical relations between the p-mode frequency shift and the change in solar activity indices. The empirical relations are determined on the basis of frequencies obtained from BBSO and GONG stations during solar cycle 22. These relations are applied to estimate the change in mean frequency for the cycle 21 and 23. A remarkable agreement between the calculated and observed fre...
