New dispersive elements providing relative high resolution (R=2200) have been recently incorporated in the near infrared spectrograph LIRIS. These elements are founded on a rather novel design based on a diffractive pattern engraved in fused silica, which is placed between two prisms. These new components are pushing forward the scientific

Context: The compact association Cygnus OB2 is known to contain a large population of massive stars, but its total mass is currently a matter of debate. While recent surveys have uncovered large numbers of OB stars in the area around Cyg OB2, detailed study of the optically brightest among them suggests that most are not part of the association

The scanning Fabry-Perot spectrograph could give highly accurate, kinematical information of star forming regions (HH objects, protoplanetary disks and large scale flows) and the dynamics of isolated and interacting galaxies (resonances, galaxy pairs, compact groups). In this project we are developing a high spectral resolution scanning Fabry-Perot

The DOMENG project has introduced the Domain Engineering Process to the space community as a first stone on the roadmap to build a model-based and reused- oriented software production system, based on the analysis and modelling of the Space domain. At the current stage, the first iteration of the domain engineering process is close to an end and

We present the first results of a project aimed at the combined study of massive stars and their surrounding nebulae by means of a detailed study of Galactic H II regions ionized by only one massive star. With this, we intend to check the validity of the new generation of massive star model atmosphere codes in terms of ionizing flux distribution
