Chemical abundances in metal-poor giants: limitations imposed by the use of classical 1D stellar atmosphere models
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
In this work we have used 3D hydrodynamical (CO5BOLD) and 1D hydrostatic (LHD) stellar atmosphere models to study the importance of convection and horizontal temperature inhomogeneities in stellar abu...
Accuracy and Limitations of Fitting and Stereoscopic Methods to Determine the Direction of Coronal Mass Ejections from Heliospheric Imagers Observations
Solar and Stellar Astrophysics (astro-ph.SR) Space Physics (physics.space-ph)
2010/12/28
Using data from the Heliospheric Imagers (HIs) onboard STEREO, it is possible to derive the direction of propagation of coronal mass ejections (CMEs) in addition to their speed with a variety of metho...
The Mars Orbiter Laser Altimeter dataset：Limitations and improvements
Mars Orbiter Laser Altimeter Limitations improvements
2009/6/1
This paper highlights the limitations of the Mars Orbiter Laser Altimeter (MOLA) dataset, and presents an improved alternative: UWMOLA, based on a different interpolation algorithm.
