Helioseismic Studies of Differential Rotation in the Solar Envelope by the Solar Oscillations Investigation Using the Michelson Doppler Imager
The splitting of the frequencies of the global resonant acoustic modes of the Sun by large-scale flows and rotation permits study of the variation of angular velocity Ω with both radius and latitudeExpand
The opacity mechanism in B-type stars – II. Excitation of high-order g-modes in main-sequence stars
We show that the OPAL opacities, in addition to explaining the origin of the pulsations of β Cep stars, also predict the existence of a large region in the main-sequence band at lower luminosities,Expand
Inferring the sun's internal angular velocity from observed p-mode frequency splittings
The sun's internal solar velocity Omega is studied as a function of latitude and radius using the solar oscillation data of Brown and Morrow (1987). An attempt is made to separate robust inferencesExpand
Asteroseismology of the β Cephei star ν Eridani: interpretation and applications of the oscillation spectrum
The oscillation spectrum of v Eri is the richest known for any variable of the β Cephei type. We interpret the spectrum in terms of normal mode excitation and construct seismic models of the star.Expand
Photometric amplitudes and phases of nonradial oscillation in rotating stars
Effects of rotational mode coupling on photometric parameters of stellar oscillations are studied. At moderate rotation rates, a strong coupling between modes of spherical harmonic degree, $\ell$,Expand
The two hybrid B-type pulsators: ν Eridani and 12 Lacertae
The rich oscillation spectra determined for the two stars, ν Eridani and 12 Lacertae, present an interesting challenge to stellar modelling. The stars are hybrid objects showing not only a number ofExpand
Kepler observations of δ Scuti stars
We analyse observations of 1568 δ Scuti stars in the public archive of the Kepler satellite. We compare the location of these stars in the Hertzsprung–Russell (HR) diagram with that calculated byExpand
Oscillations of α UMa and other red giants
There is growing observational evidence that the variability of red giants could be caused by self-excitation of global modes of oscillation. The most recent evidence of such oscillations wasExpand
Period-luminosity relations in evolved red giants explained by solar-like oscillations
Context. Solar-like oscillations in red giants have been investigated with the space-borne missions CoRoT and Kepler, while pulsations in more evolved M giants have been studied with ground-basedExpand
The oblique pulsator model revisited
The oblique pulsator model accounts for most of the pulsation properties of the rapidly oscillating Ap (roAp) stars. The model predicts that modes are seen as equidistant multiplets separated by theExpand
