Condizione: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | The present book consists of four chapters as: - The first chapter represents a general survey for different types of variable stars with more concentration on the eclipsing binaries and pulsating stars. - The second chapter deals about importance of study of eclipsing binaries and their light curves classifications, also concentrate on theories of their formation and evolution. - Chapter three through some light on the pulsation theory and deal about the mechanism of pulsation and with more details about the types of stellar oscillations with some mathematical descriptions. - The fourth chapter describe the special class of double and multiple stellar systems with variable components. We also give a short notes about some published work in this branch and speak about our future plan of work in this part.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Variable star studies play an important roles in understanding the physical properties of the galaxies and clusters they are present in. The stars in globular clusters are believed to have formed roughly at the same time (although there is also mounting evidence that some clusters have formed via several episodes of star formation), from the same primordial material, and with the same composition. This should lead to a homogeneity in certain fundamental properties of the stars within each cluster, but with differences between the clusters. Knowledge about these properties, such as metallicity, age, and kinematics, are therefore important. One way to obtain better constraints on some of these physical parameters is to study the population of variable stars, especially RR Lyrae stars. Observing variable stars in different galaxy environments makes it possible to relate the types of variable stars to the stellar populations in their host galaxies.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 72 pp. Englisch.

Neuware -El estudio de las estrellas variables desempeña un papel importante en la comprensión de las propiedades físicas de las galaxias y los cúmulos en los que están presentes. Se cree que las estrellas de los cúmulos globulares se formaron aproximadamente al mismo tiempo (aunque cada vez hay más pruebas de que algunos cúmulos se han formado a través de varios episodios de formación estelar), a partir del mismo material primordial y con la misma composición. Esto debería conducir a una homogeneidad en ciertas propiedades fundamentales de las estrellas dentro de cada cúmulo, pero con diferencias entre los cúmulos. Por tanto, es importante conocer estas propiedades, como la metalicidad, la edad y la cinemática. Una forma de obtener mejores restricciones sobre algunos de estos parámetros físicos es estudiar la población de estrellas variables, especialmente las estrellas RR Lyrae. La observación de estrellas variables en diferentes entornos galácticos permite relacionar los tipos de estrellas variables con las poblaciones estelares de sus galaxias anfitrionas.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 72 pp. Spanisch.

Neuware -L'étude des étoiles variables joue un rôle important dans la compréhension des propriétés physiques des galaxies et des amas dans lesquels elles sont présentes. On pense que les étoiles des amas globulaires se sont formées à peu près en même temps (bien qu'il y ait de plus en plus de preuves que certains amas se sont formés après plusieurs épisodes de formation d'étoiles), à partir du même matériau primordial et avec la même composition. Il devrait en résulter une homogénéité de certaines propriétés fondamentales des étoiles au sein de chaque amas, mais aussi des différences entre les amas. Il est donc important de connaître ces propriétés, telles que la métallicité, l'âge et la cinématique. Une façon d'obtenir de meilleures contraintes sur certains de ces paramètres physiques est d'étudier la population d'étoiles variables, en particulier les étoiles RR Lyrae. L'observation d'étoiles variables dans différents environnements galactiques permet de relier les types d'étoiles variables aux populations stellaires de leurs galaxies hôtes.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 68 pp. Französisch.
