It was noted earlier by several authors that the infrared excess Hα emission observed from Be stars are not compatible with the idea that both emissions occur from these same optically thin ionised region. We show here ...

During routine monitoring of the Be star HR 4123 during the year 1987-1988, a burst of H-alpha emission was observed on May 11, 1987. The increase was observed on May 9 and lasted until June 7, peaking to an equivalent ...

We have observed 18 Be stars in the radio continuum at 2cm wavelength with the VLA on 7th February 1987. We observed 12 of the stars the same night in the optical using an H alpha filter and the rest subsequently. No radio ...
