| Abstract: |
The results of CORAVEL-type scanner RV measurements of F0p SrCrEu stars 49 Cam and γ Equ are presented. We have found the long term variability of RV of 49 Cam from -0.81 to + 16.22 km/s which can be due to binary motion. 758 new RVs of γ Equ obtained during 1994-1996 didn't show any long-term variability within the errors and are close to -16.8 km/s. Our result is in agreement with previous determinations of RVs for γ Equ and does not confirm the rapid radial velocity changes detected by Scholz et al.(1997) during 1994-1996 and his conclusion about binarity of γ Equ. |
