A new study of the spectroscopic binary 7 Vul with a Be star primary
P. Harmanec, J. Lipták, P. Koubský +5
We confirmed the binary nature of the Be star 7~Vul, derived a~more accurate spectroscopic orbit with an orbital period of (69.4212+/-0.0034) d, and improved the knowledge of the b…
A new look into putative duplicity and pulsations of the Be star CMi
P. Harmanec, M. Svanda, D. Korcakova +6
Bright Be star beta CMi has been identified as a non-radial pulsator on the basis of space photometry with the MOST satellite and also as a single-line spectroscopic binary with a…
Confirmation of the Planet Hypothesis for the Long-period Radial Velocity Variations of Beta Geminorum
A. P. Hatzes, W. D. Cochran, M. Endl E. W. Guenther +6
We present precise stellar radial velocity measurements for the K giant star Beta Gem spanning over 25 years. These data show that the long period low amplitude radial velocity var…
Abundances from disentangled component spectra of close binary stars: An observational test of an earlz mixing in high-mass stars
K. Pavlovski, D. E. Holmgren, P. Koubsky +2
Recent theoretical calculations of stellar evolutionary tracks for rotating high-mass stars suggests that the chemical composition of the surface layers changes even whilst the sta…
