On the possible variability of the main sequence A stars θ Virginis and 109 Virginis.

ADELMAN S.J.

Abstract (from CDS):

Differential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are used to examine the possible variability of the spectrophotometric standards θ Vir and 109 Vir. No evidence is found for variability within a season of observation. Small year to year differences are most likely due to unaccounted for extinction changes.
