Spectral synthesis analysis and radial velocity study of the northern F-, G-, and K-type flare-stars
B. König, E. W. Guenther, M. Esposito +1
In this publication we present a study of the general physical, chemical properties and radial velocity monitoring of young active stars. We derive temperatures, log g, [Fe/H], v s…
Overdamping by weakly coupled environments
Massimiliano Esposito, Fritz Haake
A quantum system weakly interacting with a fast environment usually undergoes a relaxation with complex frequencies whose imaginary parts are damping rates quadratic in the couplin…
Planets of young stars: the TLS radial velocity survey
M. Esposito, E. Guenther, A. P. Hatzes +1
We report on the search for planets orbiting 46 nearby young stars performed at the State Observatory of Turingia (TLS) by means of a radial velocity survey. The aim of this progra…
Exactly solvable model of quantum diffusion
Massimiliano Esposito, Pierre Gaspard
We study the transport property of diffusion in a finite translationally invariant quantum subsystem described by a tight-binding Hamiltonian with a single energy band and interact…
