Observations of Hipparcos short-period red giant stars
Optical UBV(RI)C and infrared JHK photometry is presented ofa small sample of giant stars with short periods in the Hipparcoscatalogue. Observations were limited, but were sufficient to rule outmost of the Hipparcos periods. Radial velocity measurement were alsomade for a few stars, over six successive nights. Low-level variabilitywas detected in a few stars. It is argued that in most cases thebrightness variations are primarily due to temperature changes. Thesefindings show that high-overtone pulsations in M giant stars occur, ifat all, in a far more limited number of stars than proposed in theauthors' previous discussion of the Hipparcos data alone.
| Stars with the Largest Hipparcos Photometric Amplitudes
A list of the 2027 stars that have the largest photometric amplitudes inHipparcos Photometry shows that most variable stars are all Miras. Thepercentage of variable types change as a function of amplitude. Thiscompilation should also be of value to photometrists looking forrelatively unstudied, but large amplitude stars.
| The 74th Special Name-list of Variable Stars
We present the Name-list introducing GCVS names for 3153 variable starsdiscovered by the Hipparcos mission.
