Luminosity functions of LMXBs in different stellar environments
(2011)
Aims. Based on the archival data from the Chandra observations of nearby galaxies, we study different sub populations of low-mass X-ray binaries (LMXBs) – dynamically formed systems in globular clusters (GCs) and in the ...
Chaotic diffusion of orbits in systems with divided phase space
(EDP Sciences, 2004-12)
In this paper we discuss the relevance of diffusive processes in multidimensional Hamiltonian systems. By means of a rather simple model, we present evidence that for moderate-to-strong chaotic systems the stochastic motion ...
Metallicity and alpha-element abundance gradients along the Sagittarius Stream as seen by APOGEE
(IOP, 2020)
Using 3D positions and kinematics of stars relative to the Sagittarius (Sgr) orbital plane and angular momentum, we identify 166 Sgr stream members observed by the Apache Point Observatory Galactic Evolution Experiment ...
On the relevance of bubbles and potential flows for stellar convection
(Wiley Blackwell Publishing, Inc, 2016-03)
Recently Pasetto et al. have proposed a new method to derive a convection theory appropriate for the implementation in stellar evolution codes. Their approach is based on the simple physical picture of spherical bubbles ...
