The changing period of SZ Tauri.

TRAMMELL S.R.

Abstract (from CDS):

Recent observations of the s-Cepheid, SZ Tauri, indicate a fourth change in period. The new elements, valid after JD 2442000, are JD(max) = 2444496.578 + 3.14907 E. The new period is compared to previous work that examined the possibility of a return to a previous pulsational period.
