Low-frequency p- and g-mode solar oscillations

In order to help the detection and identification of low-frequency p- and g -modes in the solar spectrum observed by ground-based networks and SoHO exp eriments, we study the properties of low degree (l=0 - 6) low-frequency (10 0 2000 mu Hz) solar oscillations. The frequencies of p- and g-modes have be en computed for a set of solar models with updated physics. We point out th e specific properties of the oscillations of mixed character, with noticeab le amplitude both in central and external layers. We analyze the sensitivit y of low-frequency oscillations to solar parameters like age, metallicity a nd luminosity, and to various physical processes, like convective core over shoot and mass loss during the beginning of solar evolution. We estimate th e sensitivity of the splittings of these low-frequency oscillations to the core rotation.
