We report on further photometric observations of the highly variable radio binary star LSI + 61°303 performed during 1987-1990. The data obtained in these observations, together with our previously published data, show a 26.5-d modulation in the stellar intensity as well as in the stellar colour. These findings are discussed in terms of the three models suggested for the radio outbursts of the system.
- Binaries: Close
- Radio continuum: Stars
- Stars: Emission-line, Be
- Stars: Individual: LSI + 61°303
- X-rays: Stars
