Polarimetry microlensing of close-in planetary systems

, 2017
A close-in giant planetary (CGP) system has a net polarization signal whose value varies depending on the orbital phase of the planet. This polarization signal is either caused by the stellar occultation or by reflected starlight from the surface of the ...

Very large spontaneous electric polarization in BiFeO3 single crystals at room temperature and its evolution under cycling fields

, 2007
Electric polarization loops are measured at room temperature on highly pure BiFeO3 single crystals synthesized by a flux growth method. Because the crystals have a high electrical resistivity, the resulting low leakage currents allow us to measure a ...

Detecting stellar spots through polarimetry observations of microlensing events in caustic-crossing

, 2015
In this work, we investigate if gravitational microlensing can magnify the polarization signal of a stellar spot and make it be observable. A stellar spot on a source star of microlensing makes polarization signal through two channels of Zeeman effect ...
