Multicolor CCD campaign for AS 325 to support Spitzer observations
Active Dates: July 13, 2005 – Dec. 1, 2005
Abstract:
We request nightly BVRI CCD observations of the symbiotic eclipsing binary star AS 325 until December 1, 2005. The goal of the campaign is to determine the nature of this enigmatic system by looking for changes in color during the current eclipse and also to support upcoming observations with the Spitzer Space Telescope planned for September.
Justification:
AS 325 is an eclipsing binary star with a 513-day period, known for enigmatic emission lines. The campaign aims to study changes in color during eclipses and to support Spitzer Space Telescope observations.
