Short time-scale frequency and amplitude variations in the pulsations of an roAp star: HD 217522
Rodney Medupe, Donald Wayne Kurtz, Vladimir Elkin +2
Photometric observations of HD~217522 in 1981 revealed only one pulsation frequency ~mHz. Subsequent observations in 1989 showed the presence of an additional frequenc…

Time resolved spectroscopy of the cool Ap star HD 213637
V. G. Elkin, D. W. Kurtz, G. Mathys
We present an analysis of high time resolution spectra of the chemically peculiar Ap star HD 213637. The star shows rapid radial velocity variations with a period close to the phot…
