Next: V652HER AND MERGED BINARY Up: EXTREME HELIUM STARS: PULSATION Previous: MASSES . Although pulsations in EHes appear to be ubiquitous, it is not possible to summarize their properties with a single definition. ... The first discovery of pulsation in an EHe was made by Landolt (1975), who discovered a 0.1day photometric period in V652Her, and by Hill et al. (1981), who measured the radial velocity curve and demonstrated the variations were due to radial pulsation. ... 1987, Jeffery et al. ...

... Sagittarius Star Cloud . ... Stars come in all different colors. ... Most stars in the above Sagittarius Star Cloud are orange or red and relatively faint, as our Sun would appear. ... Stars like HD 82943 are main sequence G dwarf stars with temperatures and compositions similar to the Sun. Also like the Sun, HD 82943 is known to have at least two giant planets, but unlike gas giants in our solar system their orbits are not nearly circular and bring them closer to the parent star. ...

Modern Dynamic Methods of Determination of Parameters of Meteor Bodies . ... The study takes an approach in modelling the fireballs' mass and other properties from the rate of body deceleration in the atmosphere as opposed to conventionally used luminosity. An analytical model of the atmospheric entry is calculated for registered fireballs using published observational data and evaluating parameters describing drag and ablation of meteors and bolides along the luminous segment of the trajectory. ...

ENERGETIC PARTICLE EXPERIMENT DOK-2 . ... Due to much higher energy, angular and time resolution, better separation of electrons and ions it is expected that DOK-2 experiment will allow to re-examine in more details energetic particle population and related processes in magnetosphere regions covered by the spacecraft orbit. ... Thin foil in front of detector absorbes protons with energies E<400 keV so this detector measures electron spectrum in 20 - 420 keV range. ... Energy values, keV . ...

... Barthel's simple unification scheme of powerful radio galaxies and quasars, based entirely on the orientation dependent effects, has been confronted with the observed radio structures for 152 radio galaxies and 173 steep spectrum quasars. ... Singal (1993a) also showed that observed relative numbers and linear sizes of radio galaxies and quasars are inconsistent with unification even invoking a cosmic evolution in the opening angle of obscuring torus. ...
