ECLIPSING BINARIES OBSERVING PLAN

 

128 stars in our program by December 17, 2011.   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 data points in the original databases. 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 choose 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:  *NSV 1703 has been added to the program. It is a probable EA in Camelopardalis with a range V= 8.84 - 9.00 (2011, Dec. 17).

                       *V389 And has been solved by Patrick Wils using SuperWASP. The elements were then refined combining those observations with NSVS and Hipparcos data. It is a long period eccentric binary (2011, Dec.11).

 

                       *NSV 15712 has been solved by Patrick Wils using SuperWASP. The elements were then refined combining those observations with NSVS and Hipparcos data. 0.1 mag. amplitude and reflection effect with total eclipses (2011, Dec.11).

                       *NSV 18690 was solved by Patrick Wils using SuperWASP data as an EA with a period of 1.14 d. I prefer a period of 2.28 d. with similar eclipses (2011, Dec.11).

                       *NSV 1853. An eclipse was detected by David Boyd. Combination with SuperWASP, SAVS, NSVS and TASS data allowed to determined it is a short period EA/RS binary (2011, Dec.11).

 
PAST ANNOUNCEMENTS: 

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