J/ApJ/612/481   Optical brightness of ε Eri dust ring  (Proffitt+, 2004)

Limits on the optical brightness of the ε Eridani dust ring. Proffitt C.R., Sahu K., Livio M., Krist J., Calzetti D., Gilliland R., Grady C., Lindler D., Woodgate B., Heap S., Clampin M., Gull T.R., Lisse C.M. <Astrophys. J., 612, 481-495 (2004)> =2004ApJ...612..481P
ADC_Keywords: Stars, dwarfs ; Stars, distances ; Stars, diameters Keywords: circumstellar matter - stars: individual (ε Eridani) Abstract: The STIS CCD camera on the Hubble Space Telescope (HST) was used to take deep optical images near the K2 V main-sequence star ε Eridani in an attempt to find an optical counterpart of the dust ring previously imaged by submillimeter observations. Upper limits for the optical brightness of the dust ring are determined and discussed in the context of the scattered starlight expected from plausible dust models. Description: The HST observations in this program were made on 2002 January 26, using six adjacent single-orbit visits. File Summary:
