Optical and X-ray behaviour of the high mass X-ray transient A0535+26/HDE245770 in February-March 2014
F. Giovannelli, G. S. Bisnovatyi-Kogan, I. Bruni +3
The optical behaviour of the Be star in the high-mass X-ray transient A0535+26/HDE245770 shows that at periastron the luminosity is typically enhanced by 0.02 to a few tenths magni…

G. S. Bisnovatyi-Kogan, A. S. Klepnef, F. Giovannelli
The optical behaviour of the Be star in the high mass X-ray transient A0535+26/HDE245770 shows that at the periastron typically there is an enhancement in the luminosity of order 0…
