Emission geometry, radiation pattern, and magnetic topology of the magnetar XTE J1810-197 in its quiescent state
pulsars: general – stars: neutron – X-rays: individual: XTE J1810− 197
2011/10/17
The return to the quiescent state of the Anomalous X-ray pulsar XTE J1810-197 following its 2003 outburst represents a unique opportunity to probe the surface emission properties of a magnetar. The qu...
The universal red-giant oscillation pattern; an automated determination with CoRoT data
Stars oscillations - Stars interiors - Methods data analysis - Methods analytical
2010/11/12
Aims. The CoRoT and Kepler satellites have provided thousands of red-giant oscillation spectra. The analysis of these spectra requires efficient methods for identifying all eigenmode parameters.Method...
Investigation for the enrichment pattern of the element abundances in r+s star HE 0338-3945: a special r-II star?
the enrichment pattern the element abundances r+s star HE 0338-3945
2011/1/10
The very metal-poor star HE 0338-3945 shows a double-enhanced pattern of the neutron-capture elements. The study to this sample could make people gain a better understanding of s- and r-process nucleo...
Chemical pattern across the young associations ONC and OB1b
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
Abundances of iron-peak and alpha-elements are poorly known in Orion, and the available measurements yield contradictory results. Aims. We measure accurate and homogeneous elemental abundances of the ...
