PLATO : PLAnetary Transits and Oscillations of stars [PDF]

Journal of Physics: Conference Series, 2008
The PLAnetary Transits and Oscillations of stars Mission (PLATO), presented to ESA in the framework of its “Cosmic Vision” programme, will detect and characterize exoplanets by means of their transit signature in front of a very large sample of bright stars, and measure the seismic oscillations of the parent stars orbited by these planets in order to ...

Solar-Like Oscillations in a Massive Star [PDF]

Science, 2009
Star Gazing Seismology of stars provides a unique insight into physical mechanisms taking place in their interior. Like the Sun, some stars have low-amplitude pulsations that are excited by turbulent convection in their outer layers. Belkacem et al. (p.

Oscillations in rapidly rotating stars [PDF]

Astronomische Nachrichten, 2010
AbstractSpurred by the spectroscopic and interferometric observations of rapidly rotating stars and the highly accurate pulsation data coming from asteroseismology space missions, theoreticians have spent many years developing models for such stars and studying their oscillations.

Solar‐like oscillations in cluster stars [PDF]

Astronomische Nachrichten, 2010
AbstractWe present a brief overview of the history of attempts to obtain a clear detection of solar‐like oscillations in cluster stars, and discuss the results on the first clear detection, which was made by the Kepler Asteroseismic Science Consortium (KASC) Working Group 2 (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Oscillations of rapidly rotating stars [PDF]

Communications in Asteroseismology, 2007
The effects of rapid rotation on stellar pulsation is examined using an accurate 2D numerical method. We compare the results of these non-perturbative calculations with those of perturbative methods and find that frequency differences exceed 0.08 muHz on half of the modes when the rotation rate is 15% of the keplerian (break-up) limit.

TORSIONAL OSCILLATIONS OF NONBARE STRANGE STARS [PDF]

The Astrophysical Journal, 2015
Strange stars are one of the possible compact stellar objects that can be formed after a supernova collapse. We consider a model of strange star having an inner core in the color-flavor locked phase surmounted by a crystalline color superconducting layer.

Oscillation and Instabilities of Relativistic Stars [PDF]

, 2002
In this short review we discuss the relevance of ongoing research into stellar oscillations and associated instabilities for the detection of gravitational waves and the future field of ``gravitational-wave astronomy''.

Torsional oscillations of magnetized relativistic stars [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
Strong magnetic fields in relativistic stars can be a cause of crust fracturing, resulting in the excitation of global torsional oscillations. Such oscillations could become observable in gravitational waves or in high-energy radiation, thus becoming a tool for probing the equation of state of relativistic stars.
