摘要:
AbstractIn order to obtain the internal structure of a main‐sequence star such as the Sun usually one has to solve the detailed structure equations numerically. This paper is an attempt to construct analytic models for the stellar nuclear energy generation. We give closed‐form analytic results for the stellar luminosity and stellar neutrino emission rate when the radial matter density of the spherical star under consideration is linear. For the numerical estimation of the neutrino flux of a specified stellar nuclear reaction we take into account parameters of the standard solar model. The present paper gives for the first time the connection between stellar structure parameters and neutrino fluxes in an analytic stellar mo

摘要:
AbstractThis paper deals with complete analytic solution to the problem of evaluating the total net rate of nuclear energy generation and the basic integral of the luminosity of a purely gaseous star in hydrostatic equilibrium. It is assumed that the total energy production is proportional to certain powers of the density and temperature and that the density inside the star is a nonlinear function varying from the centre to the surface.

摘要:
AbstractThe interstellar lines of Call (K) and NaI (D) are the main means used to estimate the distance of the Ap star ET And to derive its position in the HRD, because the classical methods for the determination ofMare affected by some restrictions. By these means the star lies distinctly above the main sequence. The post‐main sequence evolutionary stage suggests to assume that pulsations are the reason for the observed short‐time spectroscopic and photemetric variations. Possibly, the 1.61‐day period is also caused by pulsa
