A single, complete, and coherent seismic solution for five delta Scuti stars belonging to the Praesepe cluster
The present paper discusses the seismic modelling of five δ Scuti stars belonging to the Praesepe cluster. Linear analysis is confronted with observations...
A software package for the presentation and evaluation of digitized images
A brief description is given of the IMAGE-1 software package for the presentation and evaluation of digitized images at the Osservatorio Astronomico di Trieste...
A Sounding Rocket Experiment for Spectropolarimetric Observations with the Lyα Line at 121.6 nm (CLASP)
A team consisting of Japan, USA, Spain, and Norway is developing a high-throughput Chromospheric Lyman-Alpha SpectroPolarimeter (CLASP), which is proposed to...
A spectral atlas of Landolt stars for a reliable mid-IR spectrophotometric calibration for large telescopes
It is often stated that there is no point in obtaining mid-infrared data with S/N>20, even in the best of cases, because it is impossible to obtain a...
A Spectral Diagnostic for Density-Bounded HII Regions
Our spectral diagnostic based on the intensity of the [OI]λ6300Å line indicates that many observed HII regions are indeed density-bounded. The estimated...
A spectrophotometric study of the peculiar young open cluster Berkeley 87
A spectrophotometric study of the peculiar open cluster Berkeley 87 is presented; the measurements show that most of the members are young, heavily reddened OB...
