J/A+A/355/171       TZ Boo & Y Sex orbital periods           (Qian+, 2000)

Orbital period studies of the two contact binaries TZ Bootis and Y Sextantis. Qian S., Liu Q. <Astron. Astrophys. 355, 171 (2000)> =2000A&A...355..171Q
ADC_Keywords: Binaries, eclipsing ; Ephemerides Keywords: stars: binaries: close - stars: individual: TZ Boo - stars: late-type - stars: magnetic fields - stars: individual: Y Sex Description: TZ Boo and Y Sex are two A-type contact binaries. At the set, times of light minimum of the two stars were collected.
