Physical parameters of components in close binary systems: V
S. Zola, J. M. Kreiner, B. Zakrzewski +9
The paper presents combined spectroscopic and photometric orbital solutions for ten close binary systems: CN And, V776 Cas, FU Dra, UV Lyn, BB Peg, V592 Per, OU Ser, EQ Tau, HN UMa…
Radial Velocity Studies of Close Binary Stars. XV
T. Pribulla, S. M. Rucinski, R. M. Blake +8
Radial-velocity measurements and sine-curve fits to the orbital radial velocity variations are presented for the last eight close binary systems analyzed the same way as in the pre…
DDO spectroscopic survey of MOST variable stars
Theodor Pribulla, Slavek M. Rucinski, Rainer Kuschnig +2
A spectroscopic support survey of 103 objects observed by the MOST satellite is presented; 96 are variable stars with 83 of them being new MOST variable-star detections or stars wi…
A massive binary black-hole system in OJ287 and a test of general relativity
M. J. Valtonen, H. J. Lehto, K. Nilsson +23
Tests of Einstein's general theory of relativity have mostly been carried out in weak gravitational fields where the space-time curvature effects are first-order deviations from Ne…
