Results are presented from a large observational project directed toward the detection of solar-like oscillations in an ensemble of open cluster stars. Seven groups collaborated in 1992 January to observe twelve stars in M67 with 4 m class telescopes for a one week period. High quality time series were collected on 22 telescope nights for a total

A search for stellar tidal debris of defunct dwarf galaxies around globular clusters in the inner Galactic halo
In the hierarchical formation scenario in which the outer halo of the Milky Way is the result of the continuous accretion of low-mass galaxies, a fraction of the Galactic globular cluster system might have originated in and been accreted with already extinct dwarf galaxies. In this context, we expect that the remnants of these progenitor galaxies

A search for substellar members in the Praesepe and σ Orionis clusters
We have conducted deep photometric searches for substellar members of the Praesepe (0.5-1 Gyr) and σ Orionis (3 Myr) star clusters using the Sloan i' and z' broad-band filters, with the 3.5-m and the 5-m Hale telescopes on the Calar Alto and Palomar Observatories. The total area surveyed was 1177 arcmin2 and 1122 arcmin2 towards the central regions

A Short-duration Event as the Cause of Dust Ejection from Main-Belt Comet P/2012 F5 (Gibbs)
We present observations and an interpretative model of the dust environment of the Main-Belt Comet P/2010 F5 (Gibbs). The narrow dust trails observed can be interpreted unequivocally as an impulsive event that took place around 2011 July 1 with an uncertainty of ±10 days, and a duration of less than a day, possibly of the order of a few hours. The

A software package for the presentation and evaluation of digitized images
A brief description is given of the IMAGE-1 software package for the presentation and evaluation of digitized images at the Osservatorio Astronomico di Trieste. The package makes it possible to draw isophotes in an interactive way and to have an assonometric display of the image studied.
