Asteroseismic analysis of RY Leporis: the post-main sequence HADS in a binary system
Wojciech Niewiadomski, Jadwiga DaszyÅska-Daszkiewicz, PrzemysÅaw Walczak +4
We present a comprehensive study of the pulsating primary component of the long-period binary system RY Lep. The spectral energy distribution and the absence of detectable lines in…

Discovery of the First Octupole Pulsation Mode in a delta Scuti Star: A Stationary l = 3 Sectoral Mode
S. A. Rappaport, R. Jayaraman, G. Handler +8
Aims. We are attempting to better understand how stellar pulsations in close binary systems are affected, and possibly induced, by tidal, Coriolis, and centrifugal forces. Methods.…

Asteroseismology of blue stragglers in Centauri: the case of five double-mode radial SX Phoenicis pulsators
J. DaszyÅska-Daszkiewicz, P. Walczak, P. Góra +1
We present the first extensive seismic modelling of SX Phe stars in the stellar system Cen. First, using the new values of reddening and distance modulus , a…
