Observation of a burst of high-velocity dust from α Herculis.
TATEBE K., HALE D.D.S., WISHNOW E.H. and TOWNES C.H.
Abstract (from CDS):
Interferometric observations of α Herculis at a wavelength of 11.15 µm over the period 1989-2004 show large visibility variations. These variations are interpreted as an ejection of approximately 10–6 M☉ of material in 1990 that has subsequently expanded and dissipated. The expansion rate is approximately 75 km/s, much larger than previous observations. No substantial material has been emitted during the subsequent 14 years.
