ECLIPSING BINARIES OBSERVING PLAN

 

141 stars in our program by June 23, 2009.   Join the campaign !!

The new list of unsolved eclipsing systems (most of them EA-type) is available as an Excel file for easier handling. The spreadsheet includes links to available charts and additional data for all the systems. Some of the eclipsing binaries are confirmed while others might be constant stars with erroneous datapoints in the original catalogues. Main data sources are ASAS-3, NSVS and Hipparcos although some other eclipsers may be included.
The stars are ordered by brightness so you can decide your targets according to your instruments.
You can then filter them as you want.

In the news section below we will inform as soon as more stars are added (and as some are solved and thus dropped off the list) and new charts are made.

ALL these stars have no period published. The goal is to observe them as often as possible in order to detect an eclipse and thus be able to determine the elements.

HOW TO OBSERVE THEM

 

NEWS:  *V4153 Sgr has been added to the program. It is a binocular target (V= 7.5) with unconfirmed eclipses (2009, June 23).

 
PAST ANNOUNCEMENTS: 

*  LQ Gem is another eccentric binary solved by me and dropped off the plan (2009, April 12).

*  GSC 4571-0027 is a long period unsolved EA in Ursa Minor added to the program and suitable for visual observers (V= 11.85; amplitude 0.33 mag.)  (2009, April 12)    .

*  GSC 3695-1845 in Perseus is an eccentric binary solved by Anton Paschke (2009, March 26).
