Solar radius and luminosity variations induced by the internal dynamo magnetic fields
F. Spada, R. Arlt, M. Kueker +1
Although the occurrence of solar irradiance variations induced by magnetic surface features (e.g., sunspots, faculae, magnetic network) is generally accepted, the existence of intr…
Variation of the Diameter of the Sun as Measured by the Solar Disk Sextant (SDS)
S. Sofia, T. M. Girard, U. J. Sofia +3
The balloon-borne Solar Disk Sextant (SDS) experiment has measured the angular size of the Sun on seven occasions spanning the years 1992 to 2011. The solar half-diameter -- observ…
Calculation of Solar P-mode Oscillation Frequency Splittings Based on a Two-dimensional Solar Model
Linghuai Li, Sarbani Basu, Sabatino Sofia +1
We compute the p-mode oscillation frequencies and frequency splittings that arise in a two-dimensional model of the Sun that contains toroidal magnetic fields in its interior.
Two-Dimensional Stellar Evolution Code Including Arbitrary Magnetic Fields. II. Precision Improvement and Inclusion of Turbulence and Rotation
Linghuai Li, Sabatino Sofia, Paolo Ventura +4
In the second paper of this series we pursue two objectives. First, in order to make the code more sensitive to small effects, we remove many approximations made in Paper I. Second…
2-D Stellar Evolution Code Including Arbitrary Magnetic Fields. I. Mathematical Techniques and Test Cases
L. H. Li, P. Ventura, S. Basu +2
A high-precision two-dimensional stellar evolution code has been developed for studying solar variability due to structural changes produced by varying internal magnetic fields of…
A flux tube solar dynamo model based on the competing role of buoyancy and downflows
L. H. Li, S. Sofia, G. Belvedere
A magnetic flux tube may be considered both as a separate body and as a confined field. As a field, it is affected both by differential rotation (-effect) and cyclonic convectio…
