Solar-like Oscillations: An Observational Perspective
Solar-like Oscillations Observational Perspective
2011/9/30
Solar-like oscillations are excited stochastically by convection. They occur in stars with an outer convection zone, which includes the Sun and other stars on the lower main sequence, as well as cool ...
Amplitudes of solar-like oscillations: constraints from red giants in open clusters observed by Kepler
Amplitudes solar-like oscillations: constraints clusters observed Kepler
2011/9/27
Scaling relations that link asteroseismic quantities to global stellar properties are important for gaining understanding of the intricate physics that underpins stellar pulsation. The common notion t...

We have analyzed data from a multi-site campaign to observe oscillations in the F5 star Procyon. The data consist of high-precision velocities that we obtained over more than three weeks with eleven t...
Detection of solar-like oscillations from Kepler photometry of the open cluster NGC 6819

2010/3/8
Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance and initial chemical composition allows strong tests of the theory of stellar evoluti...
Excitation of Solar-like Oscillations：From PMS to MS Stellar Models
Turbulence convection oscillations excitation sun stars:α Cen A—stars:main and pre-main sequence stars
2009/5/12
The amplitude of solar-like oscillations results from a balance
between excitation and damping. As in the sun, the excitation is attributed
to turbulent motions that stochastically excite the p mode...
