  • UBV and spectroscopic variations of V2368 Oph

    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...
  • Spectroscopic orbit of Capella

    Capella is among the few binary stars with two evolved giant components. The hotter component is a chromospherically active star within the Hertzsprung gap, while the cooler...
  • Milli-arcsecond imaging of SS Lep

    Determining the mass transfer in a close binary system is of prime importance for understanding its evolution. SS Leporis, a symbiotic star showing the Algol paradox and...
  • Radial velocities of gamma Cas

    A detailed analysis of more than 800 electronic high-resolution spectra of gamma Cas, which were obtained during a time interval of over 6000 days (16.84yr) at several...
  • VR + velocity variations of IRAS 11472-0800

    We focus here on one particular and poorly studied object, IRAS 11472-0800. It is a highly evolved post-asymptotic giant branch (post-AGB) star of spectral type F, with a large...
  • Six year spectroscopy of V2028 Cyg

    We present results of nearly six years long spectroscopic observations of the B[e] star V2028 Cyg. The presence of the cold type absorption lines combined with the hot type...
  • 9 Sgr spectra 1999-2011

    The O-type object 9 Sgr is a well-known synchrotron radio emitter. This feature is usually attributed to colliding-wind binary systems, but 9 Sgr was long considered a single...
  • {omicron} Puppis spectra

    The spectrum of the Be star omi Pup is shown to vary periodically with a period of 28.9 days. Associated data
  • Spectra of HD 120678

    We report the detection of a shell-like event in the Oe-type star HD 120678. HD 120678 has been intensively observed as part of a high-resolution spectroscopic monitoring...
  • RV catalogue of O stars in 30 Doradus

    The Tarantula Nebula in the Large Magellanic Cloud is our closest view of a starburst region and is the ideal environment to investigate important questions regarding the...
  • SB 290 radial velocity curve

    Hot subdwarf B stars (sdBs) are evolved core helium-burning stars with very thin hydrogen envelopes. To form an sdB, the progenitor has to lose almost all of its hydrogen...
  • CoRoT 102918586 light curve and spectra

    Pulsating stars in eclipsing binary systems are powerful tools to test stellar models. Binarity enables us to constrain the pulsating component physical parameters and this...
  • H{alpha} spectra of MWC 342 spectra, 2004-2010

    The catalogue presents spectra of MWC 342 (V1972 Cyg) obtained during the period 2004 to 2010 with the Coude spectrograph at the 2m telescope in Ondrejov observatory, Czech...
  • KIC 11285625: list of detected frequencies

    We present the first binary modelling results for the pulsating eclipsing binary KIC 11285625, discovered by the Kepler mission. An automated method to disentangle the pulsation...
  • 3 eclipsing high-mass binaries light curve

    We present the first results of a comprehensive photometric O-star survey performed with a robotic twin refractor at the Universitatssternwarte Bochum located near Cerro...
  • Spectra of KIC10661783

    KIC 10661783 is an eclipsing binary that shows delta Sct-like oscillations. More than 60 pulsation frequencies have been detected in its light curve as observed by the Kepler...
  • Barycentric radial velocities of Gl 586A

    The visual A component of the Gliese 586AB system is a double-lined spectroscopic binary consisting of two cool stars with the exceptional orbital eccentricity of 0.976. Such an...
  • H{alpha} spectra of {pi} Aqr

    The work is aimed at studying the circumstellar disk of the bright classical binary Be star pi Aqr. We analysed variations of a double-peaked profile of the Halpha emission line...
  • The chemically peculiar binary HD 161701

    We perform a complete study of the HgMn binary HD 161701, including the determination of physical parameters and photospheric chemical abundances. We analyzed time series of...
  • Orbital solutions of eight close sdB binaries

    The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars (sdBs) with massive compact companions such as...
