Blue stragglers in open clusters - A test of the binary hypothesisA search for binaries among 17 blue stragglers in five galactic clusters, NGC 7789, 6633, 6819, 6939, and M 67, has been performed using measurements of radial velocity variations. The spectra were obtained with the Intermediate Dispersion Spectrograph attached to the f/15 Cassegrain focus of the 2.5 m Isaac Newton Telescope at the SpanishManteiga, M. et al.

2.2 micron stellar counts at the galactic plane.The author presents 2.2 micron maps of selected areas of the galactic plane, taken with the 1.5 m. Sánchez-Magro telescope on the island of Tenerife. A model of the galactic stellar distribution has been developed. The results are in good agreement with the experimental data and suggest remarkable differences between the luminosity functions forGarzón, F.

2.2 micron stellar counts at the Galactic PlaneThis paper presents 2.2 micron maps of selected areas of the Galactic Plane, taken with the 1.5 m Sanchez-Magro telescope on the island of Tenerife. A model of the galactic stellar distribution has been developed, and the derived stellar surface densities are compared with the observations. The results are in good agreement with the experimentalGarzon, F.

The global oscillation spectrum of the sun. II - The observed low L high N solar p-mode spectrumUsing data from observing seasons 1977 through 1984, an analysis of the low l, high n p-mode solar spectra is made with a 0.9 μHz resolution. Frequencies and amplitudes of modes of l 3 and 11 n 33 are determined for each observing season. No clear variation of the frequencies at the 1 μHz level is found and the amplitudes remain constant to ˜ 20Palle, P. L. et al.
