Forty years of UBV photometry at Hvar
P. Harmanec, H. BožiÄ
The history of the program of systematic UBV photometric monitoring of Be stars, binaries, CP stars and some other targets is briefly summarized. It is shown that a careful data ho…
V2368 Oph: An eclipsing and double-lined spectroscopic binary used as a photometric comparison star for U Oph
P. Harmanec, H. BožiÄ, P. Mayer +8
The A-type star HR 6412 = V2368 Oph was used by several investigators as a photometric comparison star for the known eclipsing binary U Oph but was found to be variable by three in…
HD 174884: a strongly eccentric, short-period early-type binary system discovered by CoRoT
C. Maceroni, J. Montalban, E. Michel +12
Accurate photometric CoRoT space observations of a secondary seismological target, HD 174884, led to the discovery that this star is an astrophysically important double-lined eclip…
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…
Properties and nature of Be stars. XX. Binary nature and orbital elements of gamma Cas
P. Harmanec, P. Habuda, S. Stefl +8
An analysis of accurate radial velocities (RVs) of the Be star gamma Cas from 295 Reticon spectrograms secured between October 1993 and May 2000 allowed us to prewhiten the RVs for…
The Three body system delta Circini
P. Mayer, P. Harmanec, H. Sana +1
Delta Cir is known as an O7.5 III eclipsing and spectroscopic binary with an eccentric orbit. Penny et al. discovered the presence of a third component in the IUE spectra. The ecli…
