The Light Curve of V441 Herculis
No. 90 (Vol. 10, Part 4)
Budapest, 1987
Abstract
The light variations of the F-type supergiant V441 Her have been followed for
a period of five years in the B and V pass bands. A pulsation period of
63.9 days has been derived. The residuals show a harmonic distribution with
a period of about 1500 days. Arguments are presented in favour of a
circumstellar envelope around the F-type star and an infrared companion
to this star.
