Temperature acclimatisation of swimming performance in the European Queen Scallop [PDF]

open access: yes, 2005
The phenotypic plasticity of muscle performance and locomotory physiology allows the maintenance of essential activity capacity in the face of environmental change, and has been demonstrated in a wide phylogenetic range of eurythermal vertebrates.

Chemodynamical modeling of young disk galaxies [PDF]

open access: yes, 2003
Disk galaxies are very complex systems consisting of several components like the bulge, the disk and the halo. Additionally, substructures like extended HI disks, thin and thick stellar disks are observed.

Dynamical History of the Stars in Relation with Age, Kinematics, Abundances, Birthrate [PDF]

open access: yesInternational Astronomical Union Colloquium, 1977
A large amount of work has been devoted to correlations between kinematic properties and spectral types in order to improve our knowledge of stellar populations in our Galaxy and hence to deduce its structure and evolution. The classical results will not be repeated in the present review paper.

Kinematic model inversions of hot star recurrent DAC data – tests against dynamical CIR models [PDF]

open access: yesAstronomy & Astrophysics, 2004
The Discrete Absorption Components (DACs) commonly observed in the ultraviolet lines of hot stars have previously been modelled by dynamical simulations of Corotating Interaction Regions (CIRs) in their line-driven stellar winds. Here we apply the kinematic DAC inversion method of Brown et al.

The star formation history of Upper Scorpius and Ophiuchus

open access: yesAstronomy & Astrophysics, 2022
Context. Understanding how star formation begins and propagates through molecular clouds is a fundamental but still open question. One major difficulty in addressing this question is the lack of precise 3D kinematics and age information for young stellar populations.

The Kinematics of the Outer Galactic Disk from A and F Stars [PDF]

open access: yes, 2019
The kinematics of stars in the outer Galactic disk is poorly known. In addition to constraining the Galactic potential, knowledge of the motions of stars throughout the disk facilitates studies of non-axisymmetric motion, such as streaming motions due to

Constraining the initial conditions of NGC 2264 using ejected stars found in Gaia DR2 [PDF]

open access: yes, 2022
Fast, ejected stars have been found around several young star-forming regions, such as the Orion Nebula Cluster (ONC). These ejected stars can be used to constrain the initial density, spatial and kinematic substructure when compared to predictions from ...

Kinematics of ob stars in the nearby galactic disk [PDF]

open access: yes, 2006
The goal of this thesis is it to learn something about the kinematics and structure of the Milky Way. By analysing a sample of young stars in the nearby Galactic disk we can get to know more about the global large-scale structure of our host Galaxy ...
