New solar rotational period, the solar oblateness, and solar faculae
Journal Article
·
· Phys. Rev. Lett.; (United States)
The ''excess'' solar oblateness in 1966 and the periodicity in the residuals (most of the variance) can be described as a signal due to an approximately ellipsoidal sun rotating with a 12.2-day period, the major axis being tilted 85degree +- 1degree from the solar axis. This result, independent of physical interpretation, precludes an explanation for the solar oblateness as a ''brightness signal'' due to the appearance of facular clusters at the solar limb. (AIP)
