Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishA coordinated campaign of simultaneous X-ray and ground-based photometric and spectroscopic observations of X Persei = 3U 0352 + 30 was organized from February 14 to March 2, 1977. The optical observations show little photometric activity, a less marked Balmer excess than in 1971-72, weaker emission than in 1970, and a nearly normal intrinsic color. The H-alpha emission is double with R about equal to V. No clear correlation with the X-ray emission was found, except for the lower intensity probably related to a lower 'activity' of the optical source. A best-fit heliocentric X-ray period of 835.05 + or - 0.15 is found.
