Zeeman-Doppler Imaging of active late-type stars
(Univ. Potsdam, 2009)
Stellar magnetic fields, as a crucial component of star formation and evolution, evade direct observation at least with current and near future instruments. However investigating whether magnetic fields are generated by a ...
Critical states of seismicity
(Univ. Potsdam, 2006)
Characterization of the stellar variability in CoRoT fields with BEST telescopes
(Univ. Berlin, 2009)
The first extrasolar planet 51 Peg b around the G-type star has been reported in 1995. The planet with few Jupiter masses orbiting its star very closely was detected by measurement of the oscillation in the radial velocity ...
Study of the performance of the Pierre Auger observatory and search for primary cosmic ray photons
(Univ. Wuppertal, 2007)
Astroparticle physics is now entering the very exciting phase in which the efforts to enhance the detection capabilities of our instruments begin to turn out into clear answers. In this context the Pierre Auger Observatory ...
Equipotential Figure of Phobos Suggests Its Late Accretion Near 3.3 Mars Radii
(
- Geophysical Research Letters
, 2020-03-30)
The ellipsoidal figure of Phobos has been tentatively interpreted as resulting from accretion in a tidal environment close to its parent planet Mars. The issue is compounded by the rapid tidal decay of the moon's orbit. ...
Berechnung des seismischen Streufeldes für anisotrope Störungen
(Univ. Stuttgart, 2006)
Vorliegende Arbeit beschäftigt sich mit der Streuung der seismischen Wellen infolge unterschiedlicher, unter Anderen anisotroper, Störungen der sphärischen Symmetrie des Modells. Die Streuwellen übelagern das Referenzsignal ...
Ocean Bottom Pressure Variability: Can It Be Reliably Modeled?
(
- Journal of Geophysical Research: Oceans
, 2020)
Ocean bottom pressure (OBP) variability serves as a proxy of ocean mass variability, the knowledge of which is needed in geophysical applications. The question of how well it can be modeled by the present general ocean ...
Recordings of Fast Paleomagnetic Reversals in a 1.2 Ma Greigite-Rich Sediment Archive From Lake Ohrid, Balkans
(
- Journal of Geophysical Research: Solid Earth
, 2019)
State-of-the-art paleoclimate research strongly depends on the availability of time-equivalent markers as chronological control to disentangle interrelationships in the climate system from regional to global scale. Geomagnetic ...
Influence of Mercury's Exosphere on the Structure of the Magnetosphere
(
- Journal of Geophysical Research: Space Physics
, 2020)
Mercury is embedded in a tenuous and highly anisotropic sodium exosphere, generated mainly by plasma-surface interactions. The absolute values of the sodium ion density are still under debate. Observations by MESSENGER's ...
Linear Relationship Between Aftershock Productivity and Seismic Coupling in the Northern Chile Subduction Zone
(
- Journal of Geophysical Research: Solid Earth
, 2019)
The aftershock productivity is known to strongly vary for different mainshocks of the same magnitude, which cannot be simply explained by random fluctuations. In addition to variable source mechanisms, different rheological ...
