Description
In this work we report preliminary results of a search for shortperiod variable stars in the open cluster NGC 6531. In particular we looked for new roAp, Delta-Scuti and gamma-Doradus stars. We collected high-precision V-Bessel time-series data with the SOAR Optical Imager (SOI) at the SOAR 4.1m telescope. The data were reduced using a custom pipeline based on IRAF/PyRAF and the final light-curves were analyzed using discrete Fourier transforms (DFT). The periods and the preliminary classifications of five newly discovered variables are discussed.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta
