On the formation of warm molecular layers
The levitation of the outer atmospheres of AGB stars by pulsations is proposed as possible mechanism to form " warm molecular layers ". We compare the amounts of CO, H 2 O, CO 2 and SO 2 molecules found in an oxygen-rich dynamical model atmosphere with the values derived from recent ISO observations. In the model, the molecules are present in a layered structure behind shock waves which leads t...
متن کاملMolecular Cloud Formation in Shock-compressed Layers
We investigate the propagation of a shock wave into a warm neutral medium and cold neutral medium by one-dimensional hydrodynamic calculations with detailed treatment of thermal and chemical processes. Our main result shows that thermal instability inside the shock-compressed layer produces a geometrically thin, dense layer in which a large amount of hydrogen molecules is formed. Linear stabili...
متن کاملWarm molecular layers in protoplanetary disks
We have investigated molecular distributions in protoplanetary disks, adopting a disk model with a temperature gradient in the vertical direction. The model produces sufficiently high abundances of gaseous CO and HCO to account for line observations of T Tauri stars using a sticking probability of unity and without assuming any non-thermal desorption. In regions of radius R ∼> 10 AU, with which...
متن کاملPeBLes: Prediction of B-cell epitope using molecular layers
Characterization of B-cell protein epitope and developing critical parameters for its identification is one of the long standing interests. Using Layers algorithm, we introduced the concept of anchor residues to identify epitope. We have shown that majority of the epitope is composed of anchor residues and have significant bias in epitope for these residues. We optimized the search space reduct...
متن کاملMolecular dynamics simulations of grafted layers of bottle-brush polyelectrolytes.
Using molecular dynamics simulations, we study the effect of the brush grafting density and degree of polymerization of the side chains on conformations of brush layers made of charged bottle-brush macromolecules. The thickness of the brush layer first decreases with increasing brush grafting density; then, it saturates and remains constant in the wide interval of the brush grafting densities. ...
