Distances from Stellar Kinematics for Peculiar Virgo Cluster Spiral Galaxies
(2008)
We present distance estimates for eleven peculiar Virgo cluster spiral galaxies based on measurements of the stellar kinematics of their central 2 kpc. Stellar circular velocities were obtained using two-integral dynamical ...
Distances from stellar kinematics for peculiar Virgo Cluster spiral galaxies
(UNIV CHICAGO PRESS, 2008-08-10)
We present distance estimates for 11 peculiar Virgo Cluster spiral galaxies based on measurements of the stellar kinematics of their central 2 kpc. Stellar circular velocities were obtained using two- integral dynamical ...
On the use of rotational splitting asymmetries to probe the internal rotation profile of stars: Application to beta Cephei stars
(WILEY-V C H VERLAG GMBH, 2010)
Rotationally-split modes can provide valuable information about the internal rotation profile of stars. This has been used for years to infer the internal rotation behavior of the Sun. The present work discusses the potential ...
Differential rotation in rapidly rotating early-type stars. I: motivations for combined spectroscopic and interferometric studies.
(Edp Sciences, 2011-02)
Context. Since the external regions of the envelopes of rapidly rotating early-type stars are unstable to convection, a coupling may
exist between the convection and the internal rotation.
Aims. We explore what can be ...
Tsallis maximum entropy distribution function for stellar rotational velocities in the Pleiades
(Elsevier Inc., 2005-09-23)
In the present study we use a Tsallis maximum entropy distribution law to fit the observed distribution of projected rotational velocity measurements of stars in the Pleiades open cluster. This new distribution function ...
Lithium abundances and rotational behavior for bright giant stars
(EDP Sciences, 2005-11-16)
Aims.We study the links possibly existing between the lithium content of bright giant stars and their rotational velocity. Methods.We performed a spectral analysis of 145 bright giant stars (luminosity class II) spanning ...
