There is a long-standing debate regarding the origin of the terrestrial planets’ water as well as the hydrated C-type asteroids. Here we show that the inner Solar System's water is a simple byproduct of the giant planets’ ...

The development of technologies for obtaining and storing solar energy has brought several innovations in distinct areas such as heating, lighting, cooking as well as industrial uses. Among these technologies, solar heating ...

A solar alternative system for water heating is presented. It work on a thermosiphon, consisting of one or two alternative collectors and a water storage tank also alternative, whose main purpose is to socialize the use ...

Quality data regarding direct and diffuse solar irradiation is crucial for the proper design and simulation of solar systems. This information, however, is not available for the entire Brazilian territory. However, hourly ...

UV radiation is thought to have played an important role in the origin of life on Earth. To estimate these levels of UV radiation, we computed the UVC uxes from HST/STIS and IUE spectra of the young solar analogs κ 1 Cet ...

En este trabajo se estudian principalmente los procesos de formación y evolución planetaria en diferentes etapas. En la etapa temprana, se estudia el proceso desde la formación del disco protoplanetario hasta la formación ...
