Surface entropy of rare-gas clusters.

چکیده
Abundances of ArN+ and XeN+ clusters produced in a supersonic expansion source are inverted to find relative dissociation energies. The values around the shell and subshell closings at N=55, 71, and 147 differ from theoretical values derived from ground-state energies of Lennard-Jones clusters. A significant part of the difference can be accounted for by the conformational entropies of surface atoms and vacancies.

Modified-entropy Models for the Intracluster Medium
We present a set of cluster models that link the present-day properties of clusters to the processes that govern galaxy formation. These models treat the entropy distribution of the intracluster medium as its most fundamental property. Because convection strives to establish an entropy gradient that rises with radius, the observable properties of a relaxed cluster depend entirely on its dark-ma...
متن کاملReexamination of the Galaxy Formation-Regulated Gas Evolution Model in Groups and Clusters
As an alternative explanation of the entropy excess and the steepening of the X-ray luminosity-temperature relation in groups and clusters, the galaxy formation-regulated gas evolution (GG) model proposed recently by Bryan makes an attempt to incorporate the formation of galaxies into the evolution of gas without additional heating by nongravitational processes. This seems to provide a unified ...
متن کاملThe entropy and energy of intergalactic gas in galaxy clusters
Studies of the X-ray surface brightness profiles of clusters, coupled with theoretical considerations, suggest that the breaking of self-similarity in the hot gas results from an ‘entropy floor’, established by some heating process, which affects the structure of the intracluster gas strongly in lower mass systems. By fitting analytical models for the radial variation in gas density and tempera...
متن کاملEntropic effects on the size dependence of cluster structure.
We show that the vibrational entropy can play a crucial role in determining the equilibrium structure of clusters by constructing structural phase diagrams showing how the structure depends upon both size and temperature. These phase diagrams are obtained for example rare gas and metal clusters.
متن کاملEntropy profiles in X - ray luminous galaxy clusters at z > 0 . 1
The entropy distribution of the intracluster gas reflects both accretion history of the gas and processes of feedback which provide a further non-gravitational energy besides the potential one. In this work, we study the profiles and the scaling properties of the gas entropy in 24 hot (kTgas > 6 keV) galaxy clusters observed with Chandra in the redshift range 0.14–0.82 and showing different sta...
