CTCV J2056-3014: An X-ray-faint Intermediate Polar Harboring An Extremely Fast-spinning White Dwarf
Raimundo Lopes de Oliveira, Albert Bruch, . Claudia Vilega Rodrigues +3
We report on XMM-Newton X-ray observations that reveal CTCV J2056-3014 to be an unusual accretion-powered, intermediate polar (IP) system. It is a member of the class of X-ray-fain…
Exploratory Spectroscopy of Magnetic Cataclysmic Variables Candidates and Other Variable Objects II
Alexandre S. Oliveira, Claudia V. Rodrigues, Murilo Martins +4
This is the second paper of a series presenting our search for magnetic Cataclysmic Variables (mCVs) among candidates selected mostly from the Catalina Real-Time Transient Survey (…
Exploratory Spectroscopy of Magnetic Cataclysmic Variables Candidates and Other Variable Objects
A. S. Oliveira, C. V. Rodrigues, D. Cieslinski +5
The increasing number of synoptic surveys made by small robotic telescopes, such as the photometric Catalina Real-Time Transient Survey (CRTS), represents a unique opportunity for…
MLS110213:022733+130617: A new eclipsing polar above the period gap
K. M. G Silva, C. V. Rodrigues, A. S. Oliveira +4
This study confirms MLS110213:022733+130617 as a new eclipsing polar. We performed optical spectroscopic, polarimetric and photometric follow-up of this variable source identified…
The orbital period of the V Sge star candidate QU Carinae
A. S. Oliveira, H. J. F. Lima, J. E. Steiner +2
Close Binary Supersoft X-ray Sources (CBSS) are considered strong candidates to SN Ia progenitors, but very few CBSS are known in our Galaxy. The galactic counterparts of the CBSS…
MLS110213:022733+130617: A new eclipsing polar above the period gap
K. M. G. Silva, C. V. Rodrigues, A. S. Oliveira +4
We present new data that confirm MLS110213:022733+130617 as a new eclipsing polar. Some system properties were estimated.
