Two-colour photometry of the binary planetary nebula nuclei UU Sagitte and V477 Lyrae: oversized secondaries in post-common-envelope binaries
M. Afşar, C. İbanoǧlu
We present new V and R-passband CCD photometry of UU Sge and V477 Lyr, the eclipsing binary nuclei of the planetary nebulae Abell 63 and Abell 46, respectively. We have performed a…
A Spectroscopic Study of the Algol-type Binaries S Equulei and KO Aquilae: Absolute Parameters and Mass Transfer
F. Soydugan, A. Frasca, E. Soydugan +3
We present and analyze high-resolution optical spectra of the Algol binaries S Equ and KO Aql. New accurate radial velocities for the hotter primary components are obtained. Thanks…
The multiperiodicity of the Doradus stars HD 224945 and HD 224638 as detected from a multisite campaign
E. Poretti, C. Koen, M. Bossi +8
We discuss new photometric data collected on the gamma Dor variables HD 224945 and HD 224638. Multiperiodicity was detected in both stars, thanks to the clear spectral window of a…
1996 multisite photometric and spectral campaign on the lambda Boo star 29 Cyg
D. E. Mkrtichian, A. V. Kusakin, V. P. Malanushenko +11
The preliminary results of a 1996 multisite campaign on the pulsating lambda Bootis star 29 Cyg are presented. This campaign, initiated by the Central Asian Network (CAN), allowed…
