GALEX ultraviolet halos around bright stars
Listed in IVOA Registry (Virtual Observatory)
We have discovered ultraviolet (UV) halos extending as far as 5{deg} around four (of six) bright UV stars using data from the Galaxy Evolution Explorer satellite.
Description
These halos are due to scattering of the starlight from nearby thin, foreground dust clouds. We have placed limits of 0.58+/-0.12 and 0.72+/-0.06 on the phase function asymmetry factor (g) in the FUV (1521{AA}) and NUV (2320{AA}) bands, respectively.
We suggest that these halos are a common feature around bright stars and may be used to explore the scattering function of interstellar grains at small angles.
