2MASS 1534-2952AB
(Preview)
Astronomers Weigh the Coldest Brown Dwarfs Astronomers have used ultrasharp images obtained with the Keck Telescope and Hubble Space Telescope to determine for the first time the masses of the coldest class of "failed stars," a.k.a. brown dwarfs. With masses as light as 3 percent the m...

WOH G64
(Preview)
Astronomers resolve torus around star in another galaxy Talk about a diet! By resolving, for the first time, features of an individual star in a neighbouring galaxy, ESO's VLT has allowed astronomers to determine that it weighs almost half of what was previously thought, thereby solving the myste...

BD+43 3654
(Preview)
Title: BD+43 3654 -- a blue straggler? Authors: V.V.Gvaramadze, D.J.Bomans The astrometric data on the runaway star BD+43 3654 are consistent with the origin of this O4If star in the centre of the Cyg OB2 association, while BD+43 3654 is younger than the association. To reconcile this discrepancy...

EV Lacertae
(Preview)
NASAs Swift satellite picked up the brightest flare ever seen from a normal star other than our Sun. The flare, an explosive release of energy from a star, packed the power of thousands of solar flares. It would have been visible to the naked eye if the star had been easily observable in the night sky at t...
