Hardcover. Zustand: vg. First edition. Quarto. XXIV, 590pp. Original illustrated dust-jacket over blue cloth, with gold lettering on spine. The aim of the Symposium, the proceedings of which constitute this book, was to make a cross-check of the numerous recent results in ground-based and space observations of galactic and extragalactic stars using evolutionary models. A number of reviews and papers give the present status of these comparisons, whose astrophysical purpose is twofold: firstly, to understand as precisely as possible how stars evolve and die, and secondly, to apply the predictions of stellar evolution theory as a useful tool in a variety of astrophysical fields like chemical evolution of galaxies and cosmology. In addition to the study of various interesting stellar groups like horizontal branch stars, red giants on the asymptotic branch, nuclei of planetary nebulae, massive stars, etc., the book also presents an assessment of the current problems of binarity, pulsation, rotation and mixing in connection with evolution. All this information makes this volume essential in the field of stellar evolution and its relationship with other fields. Minor shelf wear and slight and sporadic soiling to dust-jacket. DJ in overall good+, binding and interior in very good condition.

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - 'If simple perfect laws uniquely rule the universe, should not pure thought be capable of uncovering this perfect set of laws without having to lean on the crutches of tediously assembled observations True, the laws to be discovered may be perfect, but the human brain is not. Left on its own, it is prone to stray, as many past examples sadly prove. In fact, we have missed few chances to err until new data freshly gleaned from nature set us right again for the next steps. Thus pillars rather than crutches are the observations on which we base our theories; and for the theory of stellar evolution these pillars must be there before we can get far on the right track. ' These words written by Martin Schwarzschi1d in his famous book en titled 'Structure and Evolution of the Stars'(1958) remind us how necessary and fruitful is the interplay of stellar evolution theory and observations. Clearly, observations are the great censor by their possibility of confirming or contradicting theoretical constructions. In addition, they have a driving role: new and sometimes unexpected facts may give rise to progressive ideas and stimulate further theoretical developments. In turn, theory, in its major role of sifting out and placing the facts in a logical sequence based on physical laws, must also be predictive and indicate new and pertinent observations to be undertaken.
