The first gravity determinations in Norway were made by Edward Sabine in 1823 with a pendulum instrument by Henry Kater. Seventy years later a Sterneck pendulum was acquired by the Norwegian Commission for the International Arc Measurements. It impro

Numerous global gravity field models (GGFMs) have resulted from the satellite gradiometry mission GOCE. Validation is indispensable to test the performance of the new-generation models. For this purpose independent datasets of terrestrial data are ve

The second international comparison of absolute gravimeters was held in Walferdange, Grand Duchy of Luxembourg, in November 2007, in which twenty absolute gravimeters took part. A short description of the data processing and adjustments will be prese

The ll year sunspot cycle is but one manifestation of the variability in the atmospheric activity of the Sun. For other stars Wilson (1978) demonstrated cyclic behavior in the chromospheric output as measured by variation in the strength of the Ca II

A spectrum synthesis analysis of eight spectra obtained during the non-flaring state of the cool dMe4 flare star AD Leo, yielded a mild, consistent underabundance, about 0.4 dex with respect to the Sun, for all metals. The turbulence and rotational v
