AP Columbae
Researchers have uncovered a new stellar neighbour with the discovery of the closest young star to Earth. The international team, including Simon Murphy, from the ANU Research School of Astronomy and Astrophysics, have shown that the star, named AP Columbae, is the closest so-called 'pre main-sequence? star. Their paper has been published this week in The Astronomical Journal . 'Pre main-sequence stars are much younger than the Sun. Using telescopes in Coonabarabran, Chile, Hawaii and California we have shown that the faint, red-dwarf star AP Columbae is the closest such star to the Earth,' said Mr Murphy. 'For decades it was believed that young stars only resided in vast star-forming regions like the Orion Nebula. These regions are typically several hundred light years away from the Earth.
