How Binary Stars affect Galactic Chemical Evolution
At least 60% of stars appear to be binary and about half of these are close enough to interact. Because of the enormous expansion on the AGB, many of these...
How do inaccuracies and unresolved structures in the measured solar photospheric magnetic vector influence the accuracy of coronal magnetic field models?
Solar magnetic fields are usually extrapolated into the corona starting from photospheric mag-netic measurements that can suffer from significant uncertainties...
How do massive stars form? Finding targets for MIRADAS
Observations from massive stars in H II regions can help to clarify theories of massive star formation because they show the degree of isolation under which...
How does breakup influence near-barrier fusion of weakly bound light nuclei ?
The influence on the fusion process of coupling to collective degrees of freedom has been explored. The significant enhancement of he fusion cross setion at sub...
How Fast the Nucleus of Comet Hale-Bopp was Rotating?
At the First International Conference on Comet Hale-Bopp (Canaries, 1998) many astronomers agreed with the value of the period of axial rotation of its nucleus...
How Hot are Hot Stars?: New Temperatures for mid-O types from FUSE data
We analysed high resolution spectra of Galactic O-type stars from the far-UV to the optical. We combined spectra from the Far Ultraviolet Spectroscopic Explorer...
How Important is Rotational Fission in the Trans-Neptunian Region?
We introduce the idea that rotational fission is a possible mechanism in the formation of systems of large TNOs: binary systems, complex systems (Haumea), and...
