Search for Dormant Black Holes in the OGLE Data
Mróz, P.; Kapusta, M.
Light curves of ellipsoidal variables collected by the Optical Gravitational Lensing Experiment (OGLE) were analyzed, in order to search for dormant black hole candidates. After the preselection based on the amplitude of ellipsoidal modulation, each object was investigated by means of the spectral energy distribution fit, which allowed us to selec…
The Appearance of Non-Spherical Systems. Application to LMXB
Różańska, A.; Madej, J.; Bełdycki, B. +2 more
We study the appearance of the neutron star-accretion disk system as seen by a distant observer in the UV/X-ray domain. The observed intensity spectra are computed assuming non-spherical geometry of the whole system, in which outgoing spectrum is not represented by the flux spectrum, the latter being valid for spherically symmetric objects. Intens…
One Thousand New Dwarf Novae from the OGLE Survey
Soszyński, I.; Udalski, A.; Szymański, M. K. +7 more
We present one of the largest collections of dwarf novae (DNe) containing 1091 objects that have been discovered in the long-term photometric data from the Optical Gravitational Lensing Experiment (OGLE) survey. They were found in the OGLE fields toward the Galactic bulge and the Magellanic Clouds. We analyze basic photometric properties of all sy…
