Rahimi Ardabili Department of Applied Mathematics, Faculty of Mathematics, Tabriz University, Tabriz, Islamic Republic of Iran Journal Article 2003 08 28 The linear adiabatic pulsation-periods of Mira variable stars have been derived. Approximately 270<sup>1</sup>[1]models were calculated for M = 0.7 M<sub>Θ</sub> to 2 M<sub>Θ</sub> stars with radii from 180 R<sub>Θ</sub> to 340 R<sub>Θ</sub> and luminosities from 2800 L<sub>Θ</sub> to 10,000 L<sub>Θ</sub>. 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-period-radius-mass relationship have been derived for the fundamental mode. The relation has been tested on a recent data set of Mira stars in the LMC. <br clear="all" /> <sup>1 </sup>Models of various computational input are available through the author.
