Search for magnetic accretion in SW Sextantis systems
I. J. Lima, C. V. Rodrigues, C. E. Ferreira Lopes +9
SW Sextantis systems are nova-like cataclysmic variables that have unusual spectroscopic properties, which are thought to be caused by an accretion geometry having part of the mass…
New Insights into Time Series Analysis IV: Panchromatic and Flux Independent Period Finding Methods
C. E. Ferreira Lopes, N. J. G. Cross, F. Jablonski
New time-series analysis tools are needed in disciplines as diverse as astronomy, economics and meteorology. In particular, the increasing rate of data collection at multiple wavel…
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 (…
HS 2231+2441: an HW Vir system composed by a low-mass white dwarf and a brown dwarf
Leonardo A. Almeida, Augusto Damineli, Cláudia V. Rodrigues +2
HW Vir systems are rare evolved eclipsing binaries composed by a hot compact star and a low-mass main-sequence star in a close orbit. These systems provide a direct way to measure…
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…
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…
