On the incidence of \textit{WISE} infrared excess among solar analog, twin and sibling stars
Antônio D. Costa, Bruno L. Canto Martins, Izan C. Leão +4
This study presents a search for IR excess in the 3.4, 4.6, 12 and 22 m bands in a sample of 216 targets, composed of solar sibling, twin and analog stars observed by the \texti…
EELT-HIRES the high-resolution spectrograph for the E-ELT
A. Marconi, P. Di Marcantonio, V. D'Odorico +70
The first generation of E-ELT instruments will include an optical-infrared High Resolution Spectrograph, conventionally indicated as EELT-HIRES, which will be capable of providing…
New Suns in the Cosmos III: multifractal signature analysis
D. B. de Freitas, M. M. F. Nepomuceno, P. R. V. de Moraes Junior +7
In present paper, we investigate the multifractality signatures in hourly time series extracted from CoRoT spacecraft database. Our analysis is intended to highlight the possibilit…
New Suns in the Cosmos II: Differential rotation in Kepler Sun-like stars
M. L. Das Chagas, J. P. Bravo, A. D. Costa +9
The present study reports the discovery of Sun-like stars, namely main-sequence stars with , and rotation periods similar to solar values, presentin…
Search for giant planets in M67 III: excess of hot Jupiters in dense open clusters
A. Brucalassi, L. Pasquini, R. Saglia +10
Since 2008 we used high-precision radial velocity (RV) measurements obtained with different telescopes to detect signatures of massive planets around main-sequence and evolved star…
