A study of bright Southern long period variables

Lebzelter, Thomas; Hinkle, Kenneth H; Wood, Peter R; Joyce, Richard R; Fekel, Francis C


In this paper we present radial velocity curves of AGB variables that exhibit various kinds of anomalies: semiregular variables (SRVs) with typical mira periods, SRVs exceeding the mira 2.5 mag amplitude limit, miras with secondary maxima in their light curves, and a SRV with a long secondary period. The stars with reliable Hipparcos parallaxes from this and from previous studies are plotted in a log P-MK-diagram. Our objects nicely follow the log P-MK-relations determined for the LMC.
