A study of binary constraints for seismology of delta Scuti stars
Orlagh L. Creevey
Seismology of single delta Scuti stars has mainly been inhibited by failing to detect many of the theoretically predicted pulsation modes, resulting in difficulties with mode ident…
Hinode Observations of Magnetic Elements in Internetwork Areas
A. G. de Wijn, B. W. Lites, T. E. Berger +3
We use sequences of images and magnetograms from Hinode to study magnetic elements in internetwork parts of the quiet solar photosphere. Visual inspection shows the existence of ma…
Whole Earth Telescope observations of the hot helium atmosphere pulsating white dwarf EC 20058-5234
WET Collaboration, D. J. Sullivan, T. S. Metcalfe +22
We present the analysis of a total of 177h of high-quality optical time-series photometry of the helium atmosphere pulsating white dwarf (DBV) EC 20058-5234. The bulk of the observ…
The pulsation modes of the pre-white dwarf PG 1159-035
J. E. S. Costa, S. O. Kepler, D. E. Winget +74
PG 1159-035, a pre-white dwarf with T_eff=140,000 K, is the prototype of both two classes: the PG1159 spectroscopic class and the DOV pulsating class. Previous studies of PG 1159-0…
Oscillations in Procyon A: First results from a multi-site campaign
S. Hekker, T. Arentoft, H. Kjeldsen +45
Procyon A is a bright F5IV star in a binary system. Although the distance, mass and angular diameter of this star are all known with high precision, the exact evolutionary state is…
Testing the evolution of the DB white dwarf GD 358: First results of a new approach using asteroseismology
J. M. Gonzalez Perez, T. S. Metcalfe
We present a new method that investigates the evolutionary history of the pulsating DB white dwarf GD358 using asteroseismology. This is done considering the internal C/O profile,…
