Variable Star Discoveries

On this page are my suspected variable star discoveries. Following AAVSO preference, each star is listed by its GSC name, unless it doesn't have one, in which case a GSC2.3 name is shown. On the left are finder charts (courtesy of the Aladdin Sky Atlas), and on the right are phased plots and in some cases 3D models of what the system might look like. Below each plot is some information about each star, as well as a link to the AAVSO page concerning the star. The stars are listed in order of increasing right ascension. If you've got the equipment and the time, additional observations of any of these objects can be submitted to the AAVSO.

EW type eclipsing binary - AAVSO UID 000-BKK-749
Other names: 2MASS J08043368+2040077, UCAC3 222-092537

EW type eclipsing binary - AAVSO UID 000-BJK-626
Other names: UCAC3 217-099771

http://www.aavso.org/vsx/index.php?view=detail.top&oid=278121

J-K = 0.303

Top: Five night lightcurve, reduced in MPO Canopus.

Bottom: Synthetic lightcuve generated in Binary Maker (blue line) with red dots showing observed data points. Overlay is a 3D model. The fit is somewhat contrived since it was necessary to introduce a "starspot" in the more massive star to compensate for the O'Connell effect.
