Recovering variable stars in large surveys: EA Algol-type class in the Catalina Survey
A. Carmo, C. E. Ferreira Lopes, A. Papageorgiou +5
The discovery and characterization of Algol eclipsing binaries (EAs) provide an opportunity to contribute for a better picture of the structure and evolution of low-mass stars. How…
Distinguishing Circumstellar from Stellar Photometric Variability in Eta Carinae
Augusto Damineli, Eduardo Fernández-Lajús, Leonardo A. Almeida +14
The interacting binary Eta Carinae remains one of the most enigmatic massive stars in our Galaxy despite over four centuries of observations. In this work, its light curve from the…
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…
Two possible circumbinary planets in the eclipsing post-common envelope system NSVS 14256825
L. A. Almeida, F. Jablonski, C. V. Rodrigues
We present an analysis of eclipse timings of the post-common envelope binary NSVS 14256825, which is composed of an sdOB star and a dM star in a close orbit (P_{orb} = 0.110374 day…
A photometric and spectroscopic study of NSVS 14256825: the second sdOB+dM eclipsing binary
L. A. Almeida, F. Jablonski, J. Tello +1
We present an analysis of UBVRIJH photometry and phase-resolved optical spectroscopy of NSVS 14256825, an HW Vir type binary. The members of this class consist…
