Two interesting case studies of pulsating components in triple systems are highlighted in this presentation. We first report on the new results of a detailed study of the double-lined spectroscopic-visual system DG Leonis based on recent photometric and high-resolution spectroscopic data. This triple system has two components showing mild Am

Photometric observations in the VRcIc bands spanning the time interval between 2004 September 22 and 2010 November 23 were performed with six instruments on five telescopes. Most of the data were obtained with the 60/90/180cm Schmidt telescope of the Konkoly Observatory, equipped with a Photometric AT 200 camera, and with the 1-m Ritchey-Chretien-

EMIR is the near-infrared wide-field camera and multi-slit spectrograph being built for Gran Telescopio Canarias. We present here the work being done on its data processing pipeline. PyEmir is based on Python and it will process automatically data taken in both imaging and spectroscopy mode. Part of the PyEmir code can be reused by other GTC

Based on drizzled F606W and F814W images, we present quantitative structural parameters in the V-band rest-frame for all galaxies with z 1 and I814(AB) 24.5 mag in the Hubble Deep Fields North and South. Our structural parameters are based on a two-component surface brightness distribution using a Sérsic bulge and an exponential disc. Detailed

We present the results from the quantitative spectroscopic analysis of ~280 likely single O stars targeted by the IACOB and OWN surveys. This implies the largest sample of Galactic O-type stars analyzed homogeneously to date. We used the iacob-broad and iacob-gbat tools (see Simón-Díaz et al. 2011,2015) to obtain the complete set of spectroscopic

We present high-resolution images of the Sun in the near-ultraviolet spectral range between 214 nm and 397 nm as obtained from the first science flight of the 1 m SUNRISE balloon-borne solar telescope. The quiet-Sun rms intensity contrasts found in this wavelength range are among the highest values ever obtained for quiet-Sun solar surface
