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…
New Insights into Time Series Analysis III - Setting constraints on period analysis
C. E. Ferreira Lopes, N. J. G. Cross, F. Jablonski
E-science of photometric data requires automatic procedures and a precise recognition of periodic patterns to perform science as well as possible on large data. Analytical equation…
Multi-band characterization of the hot Jupiters: WASP-5b, WASP-44b and WASP-46b
M. Moyano, L. A. Almeida, C. von Essen +2
We have carried out a campaign to characterize the hot Jupiters WASP-5b, WASP-44b and WASP-46b using multiband photometry collected at the Observatório do Pico Dos Dias in Brazil.…
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…
