Observations of the magnetic fine structure of a facula.
Simultaneous spectropolarimetric observations of a facula have been carried out in 10 spectral lines with a spatial resolution of 1arcsec. Local variations of...
Observations to Detect Planets Around Eclipsing Binary Systems
We present preliminary results from the ongoing ground-based photometric observing program of the TEP (Transit of Extrasolar Planets) network to detect planets...
Observations with KIDs Interferometer Spectrum Survey (KISS)
We describe the preliminary on-sky results of the KIDs Interferometer Spectrum Survey (KISS), a spectral imager with a 1 deg field of view (FoV). The instrument...

The Real Instituto y Observatorio de la Armada (ROA) meridian circle was moved to the Estación de Altura Carlos Ulrrico Cesco in the República Argentina in 1996...
Ultra-diffuse galaxies (UDGs) have been one of the latest hypes in the extragalactic community. Although discovered a few decades ago, only recently we have had...
We overview the different classes of B-type pulsators and show from our ground-based data that current data sets are insufficient to derive the complete...
