Hypervelocity Stars

In 2005, the first hypervelocity star (HVS) was discovered by Smithsonian astronomers. These objects are defined as stars with very high velocities compared to normal star velocities in a galaxy. Some of them have velocities that exceed the escape velocity of the galaxy. They are thought to originate from encounters of binary stars with the … Continue reading Hypervelocity Stars Continue reading Continue reading

White dwarf supernovae

White dwarf supernovae only occur in a binary system, in which one of them is a white dwarf while the other can be a giant star or just a main sequence star. As far as we know, a white dwarf is the remnant of a star after the nuclear fusion inside its core has ceased,… Continue reading Continue reading
