Energy-Dependent Harmonic Ratios of the Cyclotron Features of X0331+53 in the 2004-2005 Outburst

We report on changes of the cyclotron resonance energies of the recurrent transient pulsar, X0331+53 (V0332+53). The whole RXTE data acquired in the 2004-2005 outburst were utilized. The 3-80 keV source luminosity varied between 1.7x10^36 and 3.5x10^38 ers/s, assuming a distance of 7 kpc. We confirmed that the fundamental cyclotron resonance energy changed from ~22 to ~27 keV in a clear anti-correlation to the source luminosity, and without any hysteresis effects between the rising and declining phases of the outburst. In contrast, the second harmonic energy changed from ~49 to ~54 keV, implying a weaker fractional change as a function of the luminosity. As a result, the observed resonance energy ratio between the second harmonic and the fundamental was ~2.2 when the source was most luminous, whereas the ratio decreased to the nominal value of 2.0 at the least luminous state. Although the significance of this effect is model dependent, these results suggest that the fundamental and second harmonic resonances represent different heights in the accretion column, depending on the mass accretion rate.Comment: 39 pages, 15 figures, 4 tables.

Discovery of a flux-related change of the cyclotron line energy in Her X-1

We present the results of ten years of repeated measurements of the Cyclotron Resonance Scattering Feature (CRSF) in the spectrum of the binary X-ray pulsar Her X-1 and report the discovery of a positive correlation of the centroid energy of this absorption feature in pulse phase averaged spectra with source luminosity.Our results are based on a uniform analysis of observations bythe RXTE satellite from 1996 to 2005, using sufficiently long observations of 12 individual 35-day Main-On states of the source. The mean centroid energy E_c of the CRSF in pulse phase averaged spectra of Her X-1 during this time is around 40 keV, with significant variations from one Main-On state to the next. We find that the centroid energy of the CRSF in Her X-1 changes by ~5% in energy for a factor of 2 in luminosity. The correlation is positive, contrary to what is observed in some high luminosity transient pulsars. Our finding is the first significant measurement of a positive correlation between E_c and luminosity in any X-ray pulsar. We suggest that this behaviour is expected in the case of sub-Eddington accretion and present a calculation of a quantitative estimate, which is very consistent with the effect observed in Her X-1.We urge that Her X-1 is regularly monitored further and that other X-ray pulsars are investigated for a similar behaviour.Comment: 4 pages, 2 figures, accepted by A&A Letter

Multiple Cyclotron Lines in the Spectrum of 4U 0115+63

We report phase resolved spectroscopy of the transient accreting pulsar, 4U0115+63. For the first time, more than two cylotron resonance scattering features are detected in the spectrum of an X-ray pulsar. The shape of the fundamental line appears to be complex, and this is in agreement with predictions of Monte-Carlo models. As in other pulsars, the line energies and optical depths are strong functions of pulse phase. One possible model for this is an offset of the dipole of the neutron star magnetic field.Comment: 5 pages. To appear in "Proceedings of the 5th Compton Symposium

Nonsolar astronomy with the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI)

The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) is a NASA Small Explorer satellite designed to study hard x-ray and gamma-ray emission from solar flares. In addition, its high-resolution array of germanium detectors can see photons from high-energy sources throughout the Universe. Here we discuss the various algorithms necessary to extract spectra, lightcurves, and other information about cosmic gamma-ray bursts, pulsars, and other astrophysical phenomena using an unpointed, spinning array of detectors. We show some preliminary results and discuss our plans for future analyses. All RHESSI data are public, and scientists interested in participating should contact the principal author

A Content Analysis on the Function of Magical Creatures in Fairy Tales

The purpose of this study was to determine whether or not magical creatures have a function or value within fairy tales. Specifically, do the magical creatures have a purpose within the tale or are they simply included for the magical wonder? A random sampling of ten fairy tales was used in this study. By using content analysis, characters physical and personality descriptions was compared to their role within the story as it concerned the protagonist and other relevant characters. Findings showed that the creatures do indeed have a function within the story, particularly as helpful or harmful agents who cause the characters to go through a period of magical transformation

Expanding Rural Elder Care Options: Models That Work

Rural communities and elders need better access to elder care options that enable them to continue to live in the community. Despite a larger proportion of the population over age 65 than urban and suburban America, rural communities lack the services and care coordination systems older adults need to continue living independently in their own communities as they age. In November 2008, the Rural Long Term Care Workgroup convened a national Rural Long Term Care: Access and Options Workshop to identify lessons and strategies for building and sustaining rural community-based elder care services. Finding and building on successful models is an important step towards addressing the challenges faced by rural elders seeking care options in their communities. These options include home, community, and facility-based care supported by care coordination systems that enhance autonomy and quality of life of rural elders. These proceedings of the Workshop are organized around the following topics: The challenges and opportunities for expanding rural elder care options; Five rural elder care models that work; A Rural Elder Care Options Model, a web-based, interactive tool that rural communities can use to customize the options to their specific community; The organizational attributes and strong partnerships needed to build rural community options for elder care; Strategies for increasing access and options for elder care in rural communities; and Steps to move forward in building rural communities that support elder care
