We present FCAPT differential Johnson BV and Cousins RI photometry and radial velocities of the S-type AGB stars RS Cnc, ST Her, OP Her and HR Peg. We performed multiperiodic... -
Stars with large HIP photometric amplitudes
A list of the 2027 stars that have the largest photometric amplitudes in Hipparcos Photometry shows that the most variables stars are all Miras. The percentage of variable types... -
V1103 Cas photometry
We have performed UBVRI(RcIc) photometric observations of the new eclipsing elliptic variable V1103 Cas. 74 stars in vicinity of V1103 Cas were measured in UBVRI to explore... -
Galactic-field RR Lyrae abundances and kinematics
