Dr. Nicola Scafetta has sent me his latest paper which could provide a viable mechanism for planetary influence over solar output. This paper directly challenges those within the Babcock camp that dismiss planetary theory on the grounds of no “physical mechanism”. Nicola now joins Wolff & Patrone in providing very real potential mechanisms.

The new paper is titled “Does the Sun work as a nuclear fusion amplifier of planetary tidal forcing? A proposal for a physical mechanism based on the mass-luminosity relation.”

Journal of Atmospheric and Solar-Terrestrial Physics 81–82, 27–40.

*However, a planetary tidal massaging of the solar core should continuously release additional heat to it and also favor plasma fuel mixing. Consequently, the Sun’s nuclear fusion rate should be slightly increased by tidal work and should oscillate with the tidal oscillations. In Section 3.3 we have proposed a methodology to evaluate a nuclear amplification function (Eq. (32)) to convert the gravitational potential power released in the core by tidal work into solar luminosity. The strategy is based on the fact that nuclear fusion inside a solar core is kept active by gravitational forces that continuously compress the core and very slowly release additional gravitational energy to it, as the hydrogen fuses*

into helium. Without gravitational work, no fusion activity would occur either because the two phenomena are strongly coupled ( Carroll and Ostlie, 2007 ). Thus, a simple conversion factor should exist between released tidal gravitational power and its induced solar luminosity anomaly. We can estimate it using a simple adaptation of the well-known mass-luminosity relation for main-sequence stars similar to the Sun: see Eq. (27). The average

estimated amplification factor is A = 4:25 x 106, but it may vary within one order of magnitude. In fact, there is uncertainty about the Love number that in the case of the Sun may be larger than the used factor 3/2 (see Eq. (14)), and the effective tidal dissipation factor Q likely varies with the tidal frequency and amplitude, and may be different from the used binary-star average value Q = 106 (see Eq. (18)).
