Luminosity distance and extinction by submicrometer-sized grains
Ralf Siebenmorgen, Frank Heymann, Rolf Chini
The distance to the stars is a fundamental parameter, which is determined via two primary methods - parallax and luminosity. While the parallax is a direct trigonometric method, th…
The counter-rotating stellar core of NGC 4494
L. Coccato, L. Morelli, A. Pizzella +2
Context. Kinematically decoupled cores (KDCs) are often found in the centers of early-type galaxies. Aims. We aim to investigate the kinematics, structure, and stellar populations…
Testing a non-local 1-equation turbulent convection model: A solar model
T. A. M. Braun, F. Ahlborn, A. Weiss
Turbulent convection models treat stellar convection more physically than standard mixing-length theory by including non-local effects. We recently successfully applied the Kuhfuss…
Euclid preparation XLVI. The Near-IR Background Dipole Experiment with Euclid
Euclid Collaboration, A. Kashlinsky, R. G. Arendt +217
Verifying the fully kinematic nature of the cosmic microwave background (CMB) dipole is of fundamental importance in cosmology. In the standard cosmological model with the Friedman…
