Indications of r-mode Oscillations in SOHO/MDI Solar Radius Measurements
arXiv:1503.01039 · doi:10.1088/0004-637X/804/1/47
Abstract
Analysis of solar radius measurements acquired by the Michelson Doppler Imager on the SOHO spacecraft supports previously reported evidence of solar internal r-mode oscillations in Mt Wilson radius data and in nuclear-decay data acquired at the Lomonosov Moscow State University. The frequencies of these oscillations are compatible with oscillations in a putative inner tachocline that separates a slowly rotating core from the radiative envelope.
