Variations in the sky brightness during a lunar eclipse
A total lunar eclipse is conjectured to have influence on the physical conditions of an environmental area, particularly on the brightness of the sky. The phenomenon might also be relevant on weather parameters change on Earth, such as temperature, humidity and pressure, though a straightforward correlation is not easy to establish. This work mainly aims at measuring the brightness of the sky a...
متن کاملExoplanet atmosphere. Thermal structure of an exoplanet atmosphere from phase-resolved emission spectroscopy.
Exoplanets that orbit close to their host stars are much more highly irradiated than their solar system counterparts. Understanding the thermal structures and appearances of these planets requires investigating how their atmospheres respond to such extreme stellar forcing. We present spectroscopic thermal emission measurements as a function of orbital phase ("phase-curve observations") for the ...
متن کاملLunar eclipse theory revisited Scattered sunlight in both the quiescent and the volcanically perturbed atmosphere
The residual brightness of the shadowed Moon during a lunar eclipse is attributed to unscattered sunlight rays refracted in the Earth’s atmosphere. The classical theory of lunar eclipses is built on the premise that the sunlight scattered by the gases and particles in the atmosphere contributes negligibly to the brightness of the eclipsed Moon. The current work revisits the lunar eclipse theory...

Lunar Occultations of Stars with Exoplanet Candidates
We investigate the potential of lunar occultations for the detection of very faint companions, and in particular for the possibility of detecting extrasolar planets. We review the basic concepts of the method, and discuss the quantities which are relevant for this particular application. The near-infrared range, and in particular the K and L bands (2.2 and 3.6m), ooer the best dynamic range. We...
