We recently proposed a new lucky imaging technique, the Power Spectrum Extended (PSE), adapted for image reconstruction of short-exposure astronomical images in case of weak turbulence or partial adaptive optics correction. In this communication we show applications of this technique to observations of about 30 binary stars in H band with the...
Uno de los aspectos más relevantes dentro de las directrices de adaptación al EEES es la evaluación por competencias que debe hacerse en los diferentes estudios, ya sean grados o másteres. Si bien es cierto que la mayoría de los nuevos planes de estudio incorporan en sus memorias esta nueva forma de evaluación, la realidad es que o bien se...

This paper presents orbits and masses for 22 visual double stars, partly derived using their last observations made with the speckle camera PISCO. For 13 of them we have determined their first time orbits. Masses were calculated from Hipparcos and Gaia parallaxes when available, and from dynamical parallaxes otherwise. They are compared with...

Abstract We report on observations of the extended environment of the bright Be star γ -Cas performed using intensity interferometry measurements within its H α emission line. These observations were performed using a modified version of the I2C intensity interferometry instrument installed onto the 1.54 m MéO optical metrology telescope and a...
