Mode Classification of Linear Adiabatic Oscillations of Spherically Symmetric Stars
نویسنده
چکیده
We propose a mathematical scheme to classify the eigenmodes of linear adiabatic oscillations of spherically symmetric stars, with fully taking account of the perturbation to the gravitational potential. The scheme allows us to allocate a unique and continuous integral index (the radial order) to each eigenmode with a positive squared eigenfrequency of any stellar structure, which is invariant against any continuous change in the equilibrium structure. Based on this index, we can unambiguously define the three kinds of eigenmodes of adiabatic stellar oscillations, p modes, g modes, and f modes.

This work is a study of the Earths free oscillations considering a merge of solid and liquid model. At the turn of 19th century Geophysicists presented the theory of the free oscillations for a self-gravitating, isotropic and compressible sphere. Assuming a steel structure for an Earth size sphere, they predicted a period of oscillation of about 1 hour. About 50 years later, the free oscillat...
متن کاملLINEAR PULSATION CHARACTERISTICS OF MIRA VARIABLE STARS
The linear adiabatic pulsation-periods of Mira variable stars have been derived. Approximately 2701[1]models were calculated for M = 0.7 MΘ to 2 MΘ stars with radii from 180 RΘ to 340 RΘ and luminosities from 2800 LΘ to 10,000 LΘ. The chemical composition of all models is (X,Z) = (0.7,0.02). From the result of this study, linear relations on Luminosity-Period-Mass relationship and luminosity-pe...
متن کاملAsymptotic representation of nonradial g+-modes in stars with a convective core
The asymptotic representation of linear, isentropic, low-frequency g+-modes in spherically symmetric stars developedbySmeyers et al. (1995) is extended tomore realistic stellar models composed of a convective core in adiabatic equilibrium and a radiative envelope. Bymeans of a boundary-layermethod, it is taken into account that the transition from the convective core to the radiative envelope i...
متن کاملUnstable Nonradial Oscillations on Helium Burning Neutron Stars
Material accreted onto a neutron star can stably burn in steady state only when the accretion rate is high (typically super-Eddington) or if a large flux from the neutron star crust permeates the outer atmosphere. For such situations we have analyzed the stability of nonradial oscillations, finding one unstable mode for pure helium accretion. This is a shallow surface wave which resides in the ...
متن کاملAvoided crossings in radial pulsations of neutron and strange stars
Radial pulsations of neutron stars and strange quark stars with nuclear crust are studied. The avoided crossing phenomenon occurring for the radial modes is found and discussed. Neutron star models are constructed using a realistic equation of state of dense matter and strange star models using a phenomenological bag model of quark matter. The eigenfrequencies of the three lowest modes of linea...
