Structural properties of disk galaxies. I. The intrinsic equatorial ellipticity of bulges
Context: A variety of formation scenarios have been proposed to explain the diversity of properties observed in bulges. Studying their intrinsic shape can help...
Structural properties of disk galaxies. II. Intrinsic shape of bulges
Context. Knowledge of the intrinsic shapes of galaxy components provides crucial information when constraining phenomena driving their formation and evolution...
Structure and dynamics of galaxies with a low surface-brightness disc - I. The stellar and ionized-gas kinematics
Photometry and long-slit spectroscopy are presented for a sample of six galaxies with a low surface-brightness stellar disc and a bulge. The characterizing...
Structure and dynamics of galaxies with a low surface-brightness disc - II. Stellar populations of bulges
We present the radial profiles of the Hβ, Mg and Fe line-strength indices for a sample of eight spiral galaxies with a low-surface-brightness stellar disc and a...
Structure and dynamics of isolated internetwork Ca II H bright points observed by SUNRISE
Aims: We aim to improve our picture of the low chromosphere in the quiet-Sun internetwork by investigating the intensity, horizontal velocity, size and lifetime...
Structure and Evolution of Circumstellar Shells Formed by Massive Star Winds
We follow the interaction of massive stars with their circumstellar gas over their entire life-times by combining hydrodynamic stellar evolution calculations...
Structure and evolution of low-mass Population II stars
The focus of the present paper is on the detailed description of the internal structures of low mass, population II stars, to clarify some issues about these...
Structure and star formation in disc galaxies - I. Sample selection and near-infrared imaging
We present near-infrared imaging of a sample of 57 relatively large, northern spiral galaxies with low inclination. After describing the selection criteria and...
