Dear colleagues,
I report new variable stars discovery in the course of the MISAO
Project (MisV1405 - MisV1407).
Seiichi Yoshida, MISAO Project; Nobuo Ohkura and Youichirou Nakashima,
Okayama, Japan, discovered new variable stars MisV1405 - MisV1407.
They were picked up by Seiichi Yoshida from the candidates of new
variable stars detected by the PIXY system 2 from images taken by
Nobuo Ohkura and Youichirou Nakashima. Their variations were confirmed
by Seiichi Yoshida.
Patrick Wils investigated the NSVS data and revealed that MisV1405 is
an EW type eclipsing binary with a period of 0.8398 days.
Seiichi Yoshida investigated the NSVS data and confirmed the long term
variation of MisV1406. But the NSVS data do not cover the whole light
curve and the period is uncertain.
Patrick Wils investigated the NSVS data and revealed that MisV1407 is
an EW type eclipsing binary with a period of 0.3575 days.
