Asteroseismology of the solar analogs 16 Cyg A & B from Kepler observations
T. S. Metcalfe, W. J. Chaplin, T. Appourchaux +34
The evolved solar-type stars 16 Cyg A & B have long been studied as solar analogs, yielding a glimpse into the future of our own Sun. The orbital period of the binary system is too…
Mode identification in rapidly rotating stars
D. R. Reese, M. J. Thompson, K. B. MacGregor +3
Context: Recent calculations of pulsation modes in rapidly rotating polytropic models and models based on the Self-Consistent Field method (MacGregor et al. 2007) have shown that t…
On the Structure and Properties of Differentially Rotating Main-Sequence Stars in the 1-2 M_sun Range
K. B. MacGregor, Stephen Jackson, Andrew Skumanich +1
We conduct a systematic examination of the properties of models for chemically homogeneous, differentially rotating, main-sequence stars of mass 1-2 M_sun. The models were construc…
A Strong Test of Electro-Weak Theory using Pulsating DB White Dwarf Stars as Plasmon Neutrino Detectors
D. E. Winget, D. J. Sullivan, T. S. Metcalfe +2
We demonstrate that plasmon neutrinos are the dominant form of energy loss in model white dwarf stars down to T_eff ~ 25,000 K, depending on the stellar mass. The lower end of this…
Amplitude and frequency variability of the pulsating DB white dwarf stars KUV 05134+2605 and PG 1654+160 observed with the Whole Earth Telescope
G. Handler
We have acquired new time series photometry of the two pulsating DB white dwarf stars KUV 05134+2605 and PG 1654+160 with the Whole Earth Telescope. Additional single-site photomet…
Genetic-Algorithm-based Asteroseismological Analysis of the DBV White Dwarf GD 358
T. S. Metcalfe, R. E. Nather, D. E. Winget
White dwarf asteroseismology offers the opportunity to probe the structure and composition of stellar objects governed by relatively simple physical principles. The observational r…
