The Stagger-grid: A Grid of 3D Stellar Atmosphere Models - I. Methods and General Properties

Z. Magic, R. Collet, M. Asplund +5

We present the Stagger-grid, a comprehensive grid of time-dependent, 3D hydrodynamic model atmospheres for late-type stars with realistic treatment of radiative transfer, covering…

Turbulent Diffusion in the Photosphere as Derived from Photospheric Bright Point Motion

V. I. Abramenko, V. Carbone, V. Yurchyshyn +5

On the basis of observations of solar granulation obtained with the New Solar Telescope (NST) of Big Bear Solar Observatory, we explored proper motion of bright points (BPs) in a q…

Orbital Motion of HR 8799 b,c, d using Hubble Space Telescope data from 1998: Constraints on Inclination, Eccentricity and Stability

Remi Soummer, J. Brendan Hagan, Laurent Pueyo +3

HR 8799 is currently the only multiple-planet system that has been detected with direct imaging, with four giant planets orbiting at large separations from this young late A star.…

Exploring the Galaxy Mass-Metallicity Relation at z~3-5

Tanmoy Laskar, Edo Berger, Ranga-Ram Chary

Long-duration gamma-ray bursts (GRBs) provide a premier tool for studying high-redshift star-forming galaxies thanks to their extreme brightness and association with massive stars.…

Velocities measured in small scale solar magnetic elements

Øystein Langangen, Mats Carlsson, Luc Rouppe van der Voort +1

We have obtained high resolution spectrograms of small scale magnetic structures with the Swedish 1-m Solar Telescope. We present Doppler measurements at $0\farcs{2}$ spatial resol…

Spectrum and amplitudes of internal gravity waves excited by penetrative convection in solar-type stars

B. Dintrans, A. Brandenburg, A. Nordlund +1

The excitation of internal gravity waves by penetrative convective plumes is investigated using 2-D direct simulations of compressible convection. The wave generation is quantitati…
