Rapid Variations of Narrow Absorption Line Components in the Spectrum of P Cygni
We report the detection of rapid wavelength and intensity variations of narrow components in absorption line profiles of the hot galactic supergiant P Cygni. During most of the time, in one week of observations, there were two such components present. Although the period of observation is too short for firm conclusions, the velocity curves do not contradict the photometic period of 17.3 d. Thes...
متن کاملCh Cygni. I. Observational Evidence for a Disk-jet Connection
We investigate the role of accretion in the production of jets in the symbiotic star CHCygni. Assuming that the rapid stochastic optical variations in CH Cygni come from the accretion disk, as in cataclysmic variables, we use changes in this flickering to diagnose the state of the disk in 1997. At that time, CH Cygni dropped to a very low optical state, and Karovska et al. report that a radio j...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولCH Cygni: TiO molecule as a probe of temperature variations in the atmosphere of the cool component
We report our determination of Tvib from band systems of TiO in the visible spectra of the symbiotic star CH Cygni during its 1987-89 quiescent phase as well as β And and 30 Her, which are taken as comparison stars. The problems usually met by attempting to perform quantitative analysis of the atmospheres of late M-type stars have been taken into account and discussed in detail. Assuming the LT...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
