MACHO-LMC-5MACHO-LMC-5 is a very small red dwarf in our galaxy, STAR-0516-7029 however is a blue star in the Large Magellanic Cloud. In the years 1993 - 1994 the smaller passed in front of the visual equally bright, but much more luminous blue one - a microlensing event. By that the brightness of the blue one was multiplied. And as a result in 2004 for the first time the mass of a single star (the red one) beyond the Sun could be measured directly with the help of the Hubble Telescope.Constellation: Dorado Distance: 1800 light-years Spectral class: M4-5 Mass: 0.097 * Sun Back: List of Special Stars 02/08/2007 |
