  • OGLE-II DIA BUL_SC1 field

    We present an implementation of the difference image photometry based on the Alard and Lupton optimal PSF matching algorithm. The most important feature distinguishing this...
  • UBVI Photometry in 7 open clusters

    (no description available)
  • V photometry of YY CMi

    New V photoelectric observations of the eclipsing system YY CMi, obtained at La Silla, Chile, and Merate Observatory, Italy, are presented. New times of minima and ephemeris...
  • Terzan 10, ESO456-SC38 and UKS 1 VIz photometry

    We present optical colour-magnitude diagrams for the faint bulge globular clusters Terzan 10, ESO456-SC38 and UKS 1. The giant branches are detected but the horizontal branch is...
  • BVR photometry of 10 ESO/SERC fields

    For calibration of ESO/SERC survey plates, photometric CCD sequences have been obtained for 10 ESO/SERC fields in the area 10h00m<R.A.<15h30m and...
  • DD Mon BV light curves

    New BV light curves of the short-period eclipsing binary system DD Mon have been obtained. Light-curve variability is seen in both B and V bands as compared with the light...
  • Photometry of V700 Cyg and AW Vir

    A photometric analysis of the W UMa systems V 700 Cyg and AW Vir, based on photoelectric B and V light curves, is presented. Since no spectroscopic mass-ratio is available, the...
  • Terzan 6 NTT VI photometry

    We present for the first time optical (V, I and Gunn z) colour magnitude diagrams for Terzan 6, which were collected under excellent seeing conditions with the ESO NTT...
  • VI photometry of Berkeley 66

    A colour magnitude diagram (CMD) extending to V=~19mag is given for 444 stars in the region of the galactic cluster Berkeley 66. The V and I photometry of a nearby field is also...
  • BV photometry of Blanco 1 stars

    We present the results of H{alpha}(6562A) and Li I(6708A) observations of 114 low-mass stars of the young open cluster Blanco 1. We also present observations of 30 stars in Ca...
  • VI photometry of Ton 2 cluster

    Ton 2 is among the less-known Galactic globular clusters. We present for the first time colour magnitude diagrams in the V, I bands. We used the ESO NTT telescope under an...
  • NGC 6440

    (no description available)
  • NGC4815 BV photometry

    (no description available)
  • B,V photoelectric obs. of V505 Sgr

    (no description available)
  • Integrated Photometry of open clusters

    Galactic open clusters provide an abundant sample of stellar aggregates of various sizes, ages and metal abundances, apt to constitute a template for comparison with star...
  • Mass-radius relationship of 34 Kepler planets

    Transit timing variations (TTVs) can provide useful information on compact multi-planetary systems observed by transits by setting constraints on the masses and eccentricities...
  • TOI-969 light and RV curves

    The current architecture of a given multi-planetary system is a key fingerprint of its past formation and dynamical evolution history. Long-term follow-up observations are key...
  • CHEOPS photometry of KELT-1

    Recent studies based on photometry from the Transiting Exoplanet Survey Satellite (TESS) have suggested that the dayside of KELT-1b, a strongly irradiated brown dwarf, is...
  • R-band light curves of QSO J0158-4325 images

    We report periodic oscillations in the 15-year-long optical light curve of the gravitationally lensed quasar J0158-4325 at z_s_=1.29. The signal is enhanced during a high...
  • Extreme emission line galaxies in J-PLUS

    We searched for extreme emission line galaxies (EELGs) in the J-PLUS multiband survey (Cenarro et al., 2019A&A...622A.176C). We selected them by their excess of flux in the...
