Photometry of more symbiotic candidates requested
Abstract:
Further to AAVSO Alert Notices 632 and 650, Mx. Adrian Lucy and Dr. Jeno Sokoloski (Columbia University) are requesting more AAVSO photometry in support of a continuing search for new symbiotic stars. They are looking for flickering above 0.1 mag on timescales of minutes to hours in candidate symbiotic stars, a signature of mass transfer sometimes obscured by the large luminosity of the companion red giant.
Justification:
They are looking for flickering above 0.1 mag on timescales of minutes to hours in candidate symbiotic stars, a signature of mass transfer sometimes obscured by the large luminosity of the companion red giant.
