(Master thesis / Masteroppgave, 2012)
The inverse-C shape of the bisector from the chromospheric Ca triplet spectral lines is a little understood phenomena. This spectral signature can give valuble information about the chromosphere, which is the least understood ...

(Master thesis / Masteroppgave, 2011)
Spicules are relatively small, narrow and elongated structures that stick out above the edge of the solar disk. They are very dynamic and appear as jets that shoot out into the outer solar atmosphere. Up until recently, ...

During inflation, the potential of the inflaton scalar field $\phi$,
drives the exponential expansion of the Universe. The nature of the
inflaton potential is presently unknown, but one hopes to learn more
from observations ...

We investigate scalar-field theories with a field-dependent coupling to matter and show the existence of a chameleon mechanism. The thin-shell solutions for a spherical body are found, and used to investigate the consequences ...

The thesis examines the relation between
the magnetic field as measured by MDI and
the continuum intensity at four different
wavelengths (1319, 1199, 1037 and 910Å) as
measured by SUMER. A method for copointing
the instruments ...
