Bibliographie Leo Perutz : Stand: 26. April 2010
No full textIn den gut eineinhalb Jahrzehnten, die seit der Bibliographie von Hans-Harald Müller und Wilhelm Schernus (Nr. 140) vergangen sind, hat sich die Perutz-Forschung etabliert. Dies zeigt schon ein flüchtiger quantitativer Vergleich. Der Abschnitt "Wissenschaftliche Untersuchungen" bestand damals aus einer Handvoll Magisterarbeiten und Dissertationen; in der vorliegenden Bibliographie nimmt die Sekundärliteratur mehr als die Hälfte des Raums ein. Die Rechtfertigung einer neuen Perutz-Bibliographie liegt denn auch vor allem darin, ein aktuelles, möglichst vollständiges Verzeichnis der wissenschaftlichen Literatur zu Leo Perutz (unter Einschluß der vor 1990 erschienenen Titel) vorzulegen. Der Abschnitt "Primärliteratur" schließt dagegen chronologisch an Müller und Schernus an

Email: [email protected] study presented in this paper investigates the dynamic behavior of a low earth orbit (LEO) satellite due to gravity gradient disturbances when the product of inertia terms of the spacecraft and the orbit eccentricity are considered. It is shown that the classical stable solution for the gravity gradient disturbance becomes unstable if at least one product of inertia term exceeds a critical value. Dimensional analysis technique is used to develop the significant dimensionless groups which were used to correlate the data generated from the response of the coupled roll, pitch and yaw dynamics. Based on the findings of these groups, stability maps are developed to predict the influence of the product of inertia terms on the long-term behavior of the spacecraft attitude dynamics. The developed stability maps are verified numerically and successful prediction of a spacecraft stability condition due to gravity gradient disturbance is achieved
Orbit Precision Analysis of Small Man-Made Space Objects in LEO Based on Radar Tracking Measurements
No full textThe German Space Operations Center (GSOC) performs collision avoidance for 11 LEO and 2
GEO satellites. Risk detection and maneuver decisions strongly depend on the computed probability
of collision that is driven by the anticipated orbit precision of chaser and target. While the orbits of
operational satellite are well known this is usually not the case for space debris. Therefore, an
improved collision assessment requires refined orbit determination of the chaser object.
This paper describes the achievable orbit precision for a small object based on radar
measurements. The Tracking and Imaging Radar (TIRA) of Fraunhofer FHR in Wachtberg,
Germany, was used to track the Canadian nanosatellite CanX-2 over a period of five days. CanX-2
is a triple CubeSat of the size 10x10x34 cm carrying a dual frequency GPS receiver. A reference
trajectory is established by precise orbit determination (POD) from GPS measurements. Radar
tracking measurements and derived orbital information are evaluated by comparison against the
reference orbit. Statistics of the orbit determination and orbit prediction precision using different
radar measurement data arc lengths is presented leading to a better understanding of the prediction
uncertainty of critical close approaches between an active satellite and a small object

Discovery and Characterization of Two Ultra Faint-Dwarfs Outside the Halo of the Milky Way: Leo M and Leo K
No full textWe report the discovery of two ultra-faint dwarf galaxies, Leo M and Leo K,
that lie outside the halo of the Milky Way. Using Hubble Space Telescope
imaging of the resolved stars, we create color-magnitude diagrams reaching the
old main sequence turn-off of each system and (i) fit for structural parameters
of the galaxies; (ii) measure their distances using the luminosity of the
Horizontal Branch stars; (iii) estimate integrated magnitudes and stellar
masses; and (iv) reconstruct the star formation histories. Based on their
location in the Local Group, neither galaxy is currently a satellite of the
Milky Way, although Leo K is located ~26 kpc from the low-mass galaxy Leo T and
these two systems may have had a past interaction. Leo M and Leo K have stellar
masses of 1.8 (+0.3/-0.2) x 10^4 Msun and 1.2+/-0.2 x 10^4 Msun, and were
quenched 10.6 (+2.2/-1.1) Gyr and 12.8 (+0.1/-4.2) Gyr ago, respectively. Given
that the galaxies are not satellites of the MW, it is unlikely that they were
quenched by environmental processing. Instead, given their low stellar masses,
their early quenching timescales are consistent with the scenario that a
combination of reionization and stellar feedback shut-down star formation at
early cosmic times.Comment: 12 pages, 9 figures, 1 tabl
