The Delta Scuti variable 63 Her was observed during 21 nights at two observatories (Observatorio del Teide, Tenerife Island, Spain and Observatorio Astronomico Nacional de San Pedro Martir in Baja California, Mexico). Six frequencies of pulsation are unambiguously detected, among which the fundamental radial mode, two non radial pressure-like modes

The quality of images of the Sun obtained from the ground are severely limited by the perturbing effect of the Earth's turbulent atmosphere. The post-facto correction of the images to compensate for the presence of the atmosphere require the combination of high-order adaptive optics techniques, fast measurements to freeze the turbulent atmosphere

We present preliminary results on high resolution Hα imaging of the Wolf-Rayet blue compact dwarf galaxy (BCDG) Mrk 1094. This galaxy presents a bar-shape structure and is currently undergoing a strong star formation burst distributed in several knots. Spatially resolved photometry of the different knots indicates that star formation seems to be

We describe the redmonster automated redshift measurement and spectral classification software designed for the extended Baryon Oscillation Spectroscopic Survey (eBOSS) of the Sloan Digital Sky Survey IV (SDSS-IV). We describe the algorithms, the template standard and requirements, and the newly developed galaxy templates to be used on eBOSS
