The planet HAT-P-32b is losing so much of its atmospheric helium that the trailing gas tails are among the largest structures yet known any planet outside our solar system. Three-dimensional (3D) ...

NEAR the normal positions of the diffuse series lines of both par- and ortho-helium, one finds very broad absorption lines in the spectrum of many B-type stars. The symmetry of each structure is ...
