Infrared Excess in the Be Star δ Scorpii
Infrared Excess in the Be Star δ Scorpii
We present infrared photometric observations of the Be binary system δ Scorpii obtained in 2006. The J, H, and K magnitudes are the same within the errors compared to observations taken 10 months earlier. We derive the infrared excess from the observation and compare this to the color excess predicted …
