Although the occasional malfunction of rotating polarizing elements at the beginning of the SOHO mission, which led to its stop, GOLF instrument has been...
On the nature of VX Sagitarii: Is it the first galactic super-AGB star found?
Stars with initial masses above ~10 M ⊙ have an internal evolution completely different from those in the range between 4 and ~10 M ⊙. The former are able to...
On the occurrence of tidal tails in the Carina dSph
Wide field B,V photometry of the outer regions of the Carina dwarf spheroidal galaxy is presented. Six fields were observed to a distance from the centre up to...
On the optimal station keeping control of halo orbits
Halo orbits of the earth (Farquhar, 1970) and their stationkeeping control are investigated analytically in the framework of the restricted three-body problem...
On the origin and evolution of the asteroid Ryugu: A comprehensive geochemical perspective
Presented here are the observations and interpretations from a comprehensive analysis of 16 representative particles returned from the C-type asteroid Ryugu by...
Since the use of high-resolution high signal-to-noise spectroscopy in the study of massive stars, it became clear that an ad-hoc velocity field at the stellar...
We investigate a one-zone chemo-photometric evolutionary model of truncated spiral galaxies with and without starbursts in order to explore the origin of the...
