Solar – like oscillations in Procyon A ⋆
The F5 subgiant Procyon A (α CMi, HR 2943) was observed with the Coralie fiber–fed echelle spectrograph on the 1.2–m Swiss telescope at La Silla in February 1999. The resulting 908 high–accuracy radial velocities exhibit a mean noise level in the amplitude spectrum of 0.11 m s at high frequency. These measurements show significant excess in the power spectrum between 0.6-1.6 mHz with 0.60 m s p...
متن کاملEvidence for global pressure oscillations on Procyon
Precise Doppler measurements of the star Procyon (αCMi, HR 2943) have been obtained with the ELODIE fiberfed cross-dispersed echelle spectrograph on the 1.93 m telescope at Observatoire de Haute Provence. Here, we present the analysis of data from 10 days observing run carried out in November 1998. We detect significant excess in the power between 0.5–1.5 mHz in the periodograms of the time ser...
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 اولOptimal strategies of radial velocity observations in planet search surveys
Applications of the theory of optimal design of experiments to radial velocity planet search surveys are considered. Different optimality criteria are discussed, basing on the Fisher, Shannon, and Kullback-Leibler informations. Algorithms of optimal scheduling of RV observations for two important practical problems are considered. The first problem is finding the time for future observations to...
متن کاملRadial Velocity
The radial velocity technique was utilized to make the first exoplanet discoveries and continues to play a major role in the discovery and characterization of exoplanetary systems. In this chapter we describe how the technique works, and the current precision and limitations. We then review its major successes in the field of exoplanets. With more than 250 planet detections, it is the most prol...
