The infrared variability of the eruptive variable HM Sagittae.
Abstract
Recent near infrared observations have been obtained of the peculiar eruptive variable HM Sagittae which show a general decrease in the flux levels between 1 and 5 microns during 1977-1978. The existing data are yet too sparse to ascertain the nature of the variability; however, both the IR and visual observations confirm the close resemblance of HM Sge to V1016 Cyg. A model of a binary symbiotic system containing a late type variable may be consistent with the current data.
