Statistical properties of exoplanets. II. Metallicity, orbital parameters, and space velocities
In this article we present a detailed spectroscopic analysis of more than 50 extra-solar planet host stars. Stellar atmospheric parameters and metallicities are...
Statistical properties of H II regions in the disc of M100
From a new mosaic image in the Hα line of the complete disc of the spiral galaxy M100, a catalogue is composed listing 1948 individual H II regions. I give...
Statistical redshift of the very-high-energy blazar S5 0716+714
Context. Blazars are the most numerous class of very-high-energy (VHE; E > 100 GeV) gamma-ray emitters. At present, measured redshifts are available only for...
Statistical structure of the atmospheric optical turbulence at Teide Observatory from recalibrated generalized SCIDAR data
The characterization of the optical turbulence structure at an astronomical site requires a proper data base of the refractive-index structure constant, ?. Our...
Statistical studies of HII regions in nearby galaxies. I. Spitzer near-IR luminosities and temperatures, compared with Hα luminosities, from selected HII regions in M100
Aims: We systematically study the relations between the Hα luminosity and the near-IR luminosity and temperature of a set of selected HII regions in the disc of...
Statistics and analysis of high-altitude wind above the Canary Islands observatories
High-altitude wind has been recently proposed as an important parameter to be taken into account for astronomical site selection. We present here comprehensive...
Statistics and properties of H II regions in a sample of grand design galaxies I. Luminosity functions.
We present new high quality continuum-subtracted Hα images of the grand-design galaxies NGC 157, NGC 3631, NGC 6764 and NGC 6951. We have determined the...
Statistics and properties of H II regions in a sample of grand-design galaxies. II. Physical properties.
We describe statistical properties of complete samples of HII regions in the grand-design spiral galaxies NGC 157, NGC 3631, NGC 6764 and NGC 6951. We use the...
