The future of the Sun

A team of astronomers led by Jose Dias do Nascimento (Department of Theoretical and Experimental Physics, Universidade Federal do Rio Grande do Norte [DFTE, UFRN], Brazil) has found the farthest known solar twin in the Milky Way Galaxy-- CoRoT Sol 1, which has about the same mass and chemical composition as the Sun. Spectra from…

La ricerca di esopianeti con la relatività speciale

La ricerca di nuovi mondi rappresenta una sfida significativa perché stiamo parlando di oggetti molto piccoli, deboli, e vicini alle loro stelle. Le due tecniche più promettenti utilizzano il metodo della velocità radiale, che si basa sull'oscillazione delle stelle,  ed il metodo del transito, quando i pianeti passano davanti alla stella ospite determinando una diminuzione della…

The Fast and the Furious

The Fast and the Furious

High-energy observations have strongly changed our view of isolated neutron stars, showing that these objects appear in a large variety of different classes and can exhibit substantial variability on time scales from milliseconds to years. Changes in flux and morphology have also been observed in the nebulae powered by the relativistic winds of energetic pulsars.…
