TY - JOUR ID - 407782 AU - Dušek, Jiří - Mikulášek, Zdeněk PY - 2003 TI - Preliminary analysis of light curves of the seven carbon stars JF - Contributions of the Astronomical Observatory Skalnaté Pleso VL - 33 IS - 1 SP - 13-17 EP - 13-17 PB - Astronomický ústav SAV SN - 13351842 KW - AGB stars KW - carbon stars KW - individual stars KW - stellar pulsations KW - periods KW - UBV photometry KW - Hipparcos photometry N2 - We present a preliminary analysis of light curves of the following carbon stars: WZ Cas, VY UMa, Y CVn, RY Dra, T Lyr, HK Lyr and TT Cyg, constructed on the basis of our own BV photoelectric observations done at the Brno Observatory in 1979-94 and Hipparcos observations. The analysis suggests that "semiregular" light curves of all studied stars can be faithfully expressed by a superposition of long-term changes and a set of medium-term harmonic variations (possibly pulsations) with periods from 50 to 500 days.
