A magnetic white-dwarf accretion model for the anomalous X-ray pulsar 4U 0142+61
Sarah V. Borges, Claudia V. Rodrigues, Jaziel G. Coelho +2
The quiescent emission of the anomalous X-ray pulsar (AXP) 4U 0142+61 extends over a broad range of energy, from radio up to hard X-rays. In particular, this object is unique among…
Broadband X-ray analysis of 1E 1740.7-2942: constraints on spin, inclination and a tentative black hole mass
Paulo E. Stecchini, Flavio D'Amico, Francisco Jablonski +2
1E 1740.7-2942 is one of the strongest hard X-ray emitters in the Galactic Centre region, believed to be a black hole in a high-mass X-ray binary system. Although extensively studi…
LECX: a cubesat experiment to detect and localize cosmic explosions in hard X rays
J. Braga, O. S. C. Durao, M. Castro +8
With the advent of the nanosat/cubesat revolution, new opportunities have appeared to develop and launch small (\ts 1000 cm), low-cost (\ts US$ 1M) experiments in…
Orbital period variation of KIC 10544976: Applegate mechanism versus light travel time effect
Leonardo A. Almeida, Leandro de Almeida, Augusto Damineli +6
In recent years, several close post-common-envelope eclipsing binaries have been found to show cyclic eclipse timing variations (ETVs). This effect is usually interpreted either as…
Tandem Swift and INTEGRAL Data to Revisit the Orbital and Superorbital Periods of 1E 1740.7-2942
Paulo Eduardo Stecchini, Manuel Castro, Francisco Jablonski +2
The black hole candidate 1E 1740.7-2942 is one of the strongest hard X-ray sources in the Galactic Center region. No counterparts in longer wavelengths have been identified for thi…
Comptonization in 1E 1740.7-2942 spectra from 2 to 200 keV
Manuel Castro, Taís Maiolino, Flavio D'Amico +3
Studies of the long-term spectral variations have been used to constrain the emission processes of black hole candidates. However, a common scenario which is able to explain the em…
