Amanda Karakas One of the most important research fields in astrophysics is the study of the origin of the elements. ... Asymptotic Giant Blanch (AGB) Stars: For low and intermediate-mass stars (with initial masses between about 0.8 to 8 solar masses) the most important nucleosynthesis occurs when stars evolve off the main sequence to the giant branches. ... This indicates that these stars obtained their unusual abundances via mass transfer from a previous red giant star, that has long evolved away. ...

... 8, ``Celestial Mechanics'', 2002 Expansion of the Hamiltonian of the planetary three--body problem into Poisson series in all elements using Poisson series processor PSP E. D. Kuznetsov 1 , K. V. Kholshevnikov 2 , A. V. Greb 3 1 Astronomical Observatory of Urals State University, Ekaterinburg The first step to solve it involves expansion of the corresponding Hamiltonian into Poisson series in all elements. ... As to osculating elements we deal with two systems of them. ...

SKALA, designed at the University of Cambridge, was connected to the LOFAR HBA back end in order to perform a series of tests including: antenna pattern measurements using satellite passes, measurement of the spectrum with the active SKALA element, tests of SKALA LNAs stability over time, cross correlation tests with HBA tiles (X and Y polarizations) and beam-forming using SKALA as an HBA...

... Abstract Determine the set of osculating conic orbital elements that corresponds to the state (position, velocity) of a body at some epoch. ... In general, the elements found by this routine can have two kinds of problems: - The elements are not accurate but still represent the input state accurately. ... One recommended "sanity check" on the outputs is to supply them to the CSPICE routine conics_c and compare the resulting state vector with the one supplied to this routine. ...
