Eta Carinae's historical light curve: evidence for cyclic Roche lobe overflow from the primary star
Augusto Damineli, Leonardo A. Almeida, Francisco J. Jablonski +5
The large amount of ground-based photometric measurements of Carinae obtained since 1940 have remained problematic for quantitative modeling due to the blending of flux from th…
Eclipse timing variation of GK Vir: evidence of a possible Jupiter-like planet in a circumbinary orbit
Leonardo A. Almeida, Elielson S. Pereira, Gislene M. Borges +3
Eclipse timing variation analysis has become a powerful method to discover planets around binary systems. We applied this technique to investigate the eclipse times of GK Vir. This…
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…
The Tarantula Massive Binary Monitoring project: II. A first SB2 orbital and spectroscopic analysis for the Wolf-Rayet binary R145
T. Shenar, N. D. Richardson, D. P. Sablowski +19
We present the first SB2 orbital solution and disentanglement of the massive Wolf-Rayet binary R145 (P = 159d) located in the Large Magellanic Cloud. The primary was claimed to hav…
Extinction law in the range 0.4-4.8 m and the 8620 DIB towards the stellar cluster Westerlund 1
Augusto Damineli, Leonardo A. Almeida, Robert D. Blum +4
The young stellar cluster Westerlund 1 (Wd 1: =339.6, b=0.4) is one of the most massive in the local Universe, but accurate parameters are pending on better d…
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…
Identification of strong photometric activity in the components of LHS 1070
L. A. Almeida, F. Jablonski, E. Martioli
Activity in low-mass stars is an important ingredient in the evolution of such objects. Fundamental physical properties such as age, rotation, magnetic field are correlated with ac…
