Spectral Energy Distribution Analysis of the Supersoft X-ray Source CAL 87: Multiwavelength Constraints
Paulo E. Stecchini, Francisco Jablonski, Marcos P. Diaz +3
We analyse the spectral energy distribution (SED) of the eclipsing supersoft X-ray source CAL 87 covering wavelengths from X-rays to the near-infrared. Our study incorporates 26 da…
Revised ephemeris and orbital period derivative of the supersoft X-ray source CAL 87 based on 34 years of observations
P. E. Stecchini, F. Jablonski, M. P. Diaz +4
In this study, we present an analysis of over 34 years of observational data from CAL 87, an eclipsing supersoft X-ray source. The primary aim of our study, which combines previous…
Revisiting multiwavelength data on the supersoft X-ray source CAL 83
Paulo E. Stecchini, Marcos P. Diaz, Flavio D'Amico +1
In this study we revisit public data on the supersoft X-ray source CAL 83 in the Large Magellanic Cloud. A significant part of our analysis is focused on XMM-Newton X-ray observati…
On the behavior of the black hole candidate 1E 1740.7-2942's corona based on long-term INTEGRAL database
Paulo Eduardo Stecchini, Jurandi Leão, Manuel Castro +1
One of the most straightforward ways to explain the hard X-ray spectra observed in X-ray binaries is to assume that comptonization of soft photons from the accretion disk is occurr…
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…
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…
