Twenty magnetic Chemically Peculiar (CP2) stars of the SrCrEu subgroup mostly brighter than the 7.5 visual magnitude have been investigated in the near infrared at 1.25, 1.6 and 2.2 mu . The stars HD 3980, HD 24712, HD 49976, HD 83368, HD 96616, HD 98088, HD 118022, HD 125248, HD 148898, HD 203006, and HD 220825 have been found to be variable in

We present lithium observations of 23 X-ray selected candidate members of alpha Per, which are part of a larger sample of stars identified through two ROSAT surveys of the cluster. Our observations on one hand allowed us to confirm membership for 18 of the candidates, thus suggesting that a high percentage of the whole X-ray selected candidates are

The GTC project is in charge of the construction of an optical/IR 10-meter class telescope at the Observatorio del Roque de los Muchachos in Canary Islands. The GTC control system (GCS) will be responsible for the management and operation of the telescope, including its instrumentation. Its conceptual design has been completed in summer 1997. The

The Gran Telescopio Canarias (GTC) project office is in charge of the construction of an optical/IR 10-meter class telescope at the Observatorio del Roque de los Muchachos, in Canary Islands. The conceptual design phase has been completed in summer 1997, and the design of the control system has already started its initial phases. Recently, the

Results from Hα + continuum and Johnson UBVI imaging for HCG 95 are presented in order to study the star formation history of the galaxies in the group. Based on the spatial distribution of the stellar populations, as well as the morphology of the three-galaxy system A-C1-C2, we propose two possible scenarios for the dynamical evolution of this

Deep broad-band BVRI photometry of a sample of 22 closely interacting isolated galaxy pairs is presented. The sample consists of pairs with a large variety of orbital geometries, but most of them are M51-type pairs: a small companion in the vicinity of a prominent two-armed spiral. This subsample will be later modelled in detail with N-body
