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…
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.
Optical Polarimetry and modeling of polars observed in OPD/LNA in the period 2010-2012
K. M. G. Silva, C. V. Rodrigues, J. E. R. Costa +3
In this work, we present the first results of a study of a new sample of 7 polar candidates from polarimetric data obtained at the Pico dos Dias / LNA observatory. From the four po…
Stokes imaging of AM Her systems using 3D inhomogeneous models-II. Modelling X-ray and optical data of CP Tucanae
K. M. G. Silva, C. V. Rodrigues, J. E. R. Costa +3
The viewing geometry of the polar CP Tuc that better explains its optical and X-ray light curves is controversial. Previous modelling of white-light polarimetric data considered th…
SPARC4: A Simultaneous Polarimeter and Rapid Camera in 4 Bands
C. V. Rodrigues, F. J. Jablonski, K. Taylor +13
We present the basic concept of a new astronomical instrument: SPARC4 - Simultaneous Polarimeter and Rapid Camera in 4 bands. SPARC4 combines in one instrument: (i) photometric and…
Stokes imaging of AM Her systems using 3D inhomogeneous models - I. Description of the code and an application to V834 Cen
J. E. R. Costa, C. V. Rodrigues
Polars (or AM Her systems) are cataclysmic variables without a disc due to the strong magnetic field of the white dwarf. Most of their emission comes from the region where the accr…
