Prospects for Helio- and Asteroseismology
Major progress has been made in helioand asteroseismology in recent years. In helioseismology, much of the activity has been in local helioseismology. However, the recent revision of solar surface abundances, and the resulting problems in reconciling solar models with the helioseismic inferences, have lead to renewed activity in solar modelling and global helioseismology. Interesting, although ...
متن کاملProspects for Measuring Differential Rotation in White Dwarfs Through Asteroseismology
We examine the potential of asteroseismology for exploring the internal rotation of white dwarf stars. Data from global observing campaigns have revealed a wealth of frequencies, some of which show the signature of rotational splitting. Tools developed for helioseismology to use many solar p-mode frequencies for inversion of the rotation rate with depth are adapted to the case of more limited n...
متن کاملAsteroseismology for the Masses
For many years, astronomers interested in white dwarf stars have promised that the study of these relatively simple compact objects would ultimately lead to useful information about the physics under extreme conditions of temperature and pressure. We are finally ready to make good on that promise. Using the observational techniques of the Whole Earth Telescope developed over the past decade, an...
متن کاملTowards gravitational-wave asteroseismology
We present new results for pulsating neutron stars. We have calculated the eigenfrequencies of the modes that one would expect to be the most important gravitationalwave sources: the fundamental fluid f -mode, the first pressure p-mode and the first gravitational-wave w-mode, for twelve realistic equations of state. From this numerical data we have inferred a set of “empirical relations” betwee...
متن کاملAsteroseismology: Ground Based Observational
The improvement in observational techniques to study pulsations in solarlike stars is discussed. For higher mass stars the problem is to allocate speciic eigenmodes to a set of observed frequencies. Additional observables can be used to sort out the present ambiguities.
