Title: Reliability of visual minima timing of eclipsing binaries.
Speaker: Prof. Zdenek Mikulasek
Affiliation: Masaryk University, Czech Republic
Time: November 28, 2012 (Wednesday) 9:30-10:20 a.m.
Venue: Meeting Room 401 (Main Building)
Abstract:
Plenty of mid-eclipse timings of short-periodic binaries derived from series of visual
observations appear to be an acceptable source of information for orbitalperiod analyses.
However, our thorough period analysis of nearly contact eclipsing binary BS Vul unveiled
hidden danger in usage of visual observations.
