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…
Evidence for 3XMM J185246.6+003317 as a massive magnetar with a low magnetic field
Rafael C. R. de Lima, Jonas P. Pereira, Jaziel G. Coelho +10
3XMM J185246.6+003317 is a transient magnetar located in the vicinity of the supernova remnant Kes\,79. So far, observations have only set upper limits to its surface magnetic fiel…
Breaking the degeneracy in magnetic cataclysmic variable X-ray spectral modeling using X-ray light curves
Diogo Belloni, Claudia V. Rodrigues, Matthias R. Schreiber +12
We present an analysis of mock X-ray spectra and light curves of magnetic cataclysmic variables using an upgraded version of the 3D CYCLOPS code. This 3D representation of the accr…
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…
