15 صفحه اولThe Visual Orbit of • Pegasi
We have determined the visual orbit for the spectroscopic binary • Pegasi with interferometric visibility data obtained by the Palomar Testbed Interferometer in 1997. • Peg is a double-lined binary system whose minimum masses and spectral typing suggests the possibility of eclipses. Our orbital and component diameter determinations do not favor the eclipse hypothesis : the limb-to-limb separati...
متن کاملThe Planet around 51 Pegasi
Doppler measurements of 51 Pegasi have been made from 1995 October through 1996 August, with a precision of 5 m s~1. We Ðnd a period of 4.231 days, a velocity amplitude of 56^ 1 m s~1, and a velocity curve that is essentially sinusoidal, all in excellent agreement with Mayor & Queloz. The only viable interpretation is a companion having minimum mass, m sin i \ 0.45 in a circular orbit of MJupit...
متن کاملThe solar chemical composition
We review our current knowledge of the solar chemical composition as determined from photospheric absorption lines. In particular we describe the recent significant revisions of the solar abundances as a result of the application of a time-dependent, 3D hydrodynamical model of the solar atmosphere instead of 1D hydrostatic models. This has decreased the metal content in the solar convection zon...
متن کاملChemical composition of indoor ash residues
The ash content formed after burning of materials in indoor may be harmful to environment on dumping due to high ionic and metallic concentration. Therefore, the chemical composition of various indoor ash residues derived from burning of the biomass (BM), coal (C), cow dung (CD), incense (IS) and mosquito coil (MC) materials is described in this study. Three samples each of BM, coal, CD, IS and...
