Some Cataclysmic Variables (CVs) exhibits a very long photometric period (VLPP). We calculate the properties of a hypothetical third body, initially assumed on circular--planar orbit, by matching the modelled VLPP to the observed one of four CVs stud

We present observational evidence that helps classify the non-eclipsing binary system SDSSJ 122405.58+184102.7 as a new member of the SW Sextantis (SW Sex) class. First, from the analysis of the optical light curve, we identify the presence of two pe

We present the clustering properties and halo occupation distribution (HOD) modelling of very low redshift, hard X-ray-detected active galactic nuclei (AGN) using cross-correlation function measurements with Two-Micron All Sky Survey galaxies. Spanni

Formation of S0 galaxies through mergers. Evolution in the Tully-Fisher relation since $z\sim1$

Autor: M. Carmen Eliche-Moral, Trinidad Tapia, Hector Aceves, Alejandro Borlaff, Cristina Rodríguez-Pérez, Miguel Querejeta

(Abridged version) We explore whether a scenario that combines an origin by mergers at $z\sim$1.8-1.5 with a subsequent passive evolution of the resulting S0 remnants since $z \sim$0.8-1 is compatible with observational data of S0s in the Tully-Fishe

An introduction to dynamical friction in stellar systems

Autor: Hector Aceves, Maria Colosimo

Publikováno v: American Journal of Physics. 75:139-147

An introductory exposition of Chandrasekhar’s gravitational dynamical friction, appropriate for an undergraduate class in mechanics, is presented. This friction results when a heavy particle moving through a “sea” of much lighter star particles
