Pulsation Period Change & Classical Cepheids: Probing the Details of Stellar Evolution

, 2014
Measurements of secular period change probe real-time stellar evolution of classical Cepheids making these measurements powerful constraints for stellar evolution models, especially when coupled with interferometric measurements. In this work, we present

Stellar populations of ultraluminous infrared galaxies

, 2011
Ultraluminous infrared galaxies (ULIRGs) have several types according to dominance of starburst or AGN component. We made stellar population analysis for a sample of 160 ULIRGs to study the evolution of ULIRGs. We found that the dominance of intermediate-

Monte Carlo Simulations of Globular Cluster Evolution. V. Binary Stellar Evolution

, 2009
We study the dynamical evolution of globular clusters containing primordial binaries, including full single and binary stellar evolution using our Monte Carlo cluster evolution code updated with an adaptation of the single and binary stellar evolution ...

Rotation and stellar evolution [PDF]

EPJ Web of Conferences, 2013
The effects of rotation on the evolution and properties of low-mass stars are first discussed from the pre-main sequence to the red giant phase. We then briefly indicate how some observational constraints available for these stars can help us progress in our understanding of the dynamical processes at work in stellar interiors.

Wind anisotropy and stellar evolution [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractMass loss is a determinant factor which strongly affects the evolution and the fate of massive stars. At low metallicity, stars are supposed to rotate faster than at the solar one. This favors the existence of stars near the critical velocity. In this rotation regime, the deformation of the stellar surface becomes important, and wind anisotropy

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

Population Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

The coevolution of the velocity and mass functions of galaxies and dark haloes

, 2010
We employ a bias-corrected abundance matching technique to investigate the coevolution of the LCDM dark halo mass function (HMF), the observationally derived velocity dispersion and stellar mass functions (VDF, SMF) of galaxies between z=1 and 0.

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

Population Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

On Stellar Structure and Evolution

, 2021
In this paper, an exposition has been provided on the structure and evolution of stars based on the major functionality on their initial mass. First, we deal with the role of the radiation pressure and its contribution in the overall equilibrium of the stellar stability, then we discuss about the formation of white dwarfs and Newtonian polytropes, then
