Periodicities in solar coronal mass ejections

Wang, Shui; Fan, Zuhui; Lou, Yu-Qing +2 more

Mid-term quasi-periodicities in solar coronal mass ejections (CMEs) during the most recent solar maximum cycle 23 are reported here for the first time using the four-year data (1999 February 5 to 2003 February 10) of the Large Angle Spectrometric Coronagraph on board the Solar and Heliospheric Observatory. In parallel, mid-term quasi-periodicities…

The sensitivity of the seismic solar model to Newton's constant

Silk, Joseph; Lopes, Ilídio P.

New experimental determinations of Newton's gravitational constant have been recently given. There are significant disagreements between these new measurements. We show that the high accuracy obtained with current standard solar models is such that the uncertainties in core temperature profiles arising from the uncertainties in G can be comparable…
